1-6 system manual c79000-g8576-c199-07 notes for machine manufacturers the simatic programmable controller is not a machine in the sense of the ec directive on machines. therefore, there is no declaration of conformity for simatic as regards the ec directive 89/392/eec on machines. the ec directive 89/392/eec on machines controls machine requirements. here, a machine is understood to be the entire sum of devices or parts involved (see also en 292-1, paragraph 3.1). simatic is part of the electrical equipment for a machine and must therefore be included in the procedure for checking conformity by the machine manufacturer. the en 60204-1 standard (machine safety, general requirements for the electrical equipment for machines) applies to the electrical equipment for machines. the following table should help you with the declaration of conformity and shows which criteria apply to en 60204-1 (as at june 1993) for simatic. en 60204-1 subject/criterion remarks para. 4 general requirements requirements are fulfilled if the machines are assembled/installed according to the installation guidelines. see also the explanations on the previous pages. para. 11.2 digital i/o interfaces requirements are fulfilled. para. 12.3 programmable equipment requirements are fulfilled if the machines are installed in lockable cabinets to protect them from memory modifications by unauthorized persons. para. 20.4 voltage tests requirements are fulfilled. introduction ec directive 89/392/eec on machines electrical equipment for machines to en 60204 notes on usin g this manual and on the ce s y mbol
1-7 system manual c79000-g8576-c199-07 safety notes risks involved in the use of so-called simatic-compatible modules of non-siemens manufacture athe manufacturer of a product (simatic in this case) is under the general obligation to give warning of possible risks attached to his product. this obligation has been extended in recent court rulings to include parts supplied by other vendors. accordingly, the manufacturer is obliged to observe and recognize such hazards as may arise when a product is combined with products of other manufacture. for this reason, we feel obliged to warn our customers who use simatic products not to install so-called simatic-compatible modules of other manufacture in the form of replacement or add-on modules in simatic systems. our products undergo a strict quality assurance procedure. we have no knowledge as to whether outside manufacturers of so-called simatic-compatible modules have any quality assurance at all or one that is nearly equivalent to ours. these so-called simatic-compatible modules are not marketed in agreement with siemens; we have never recommended the use of so-called simatic-compatible modules of other manufacture. the advertising of these other manufacturers for so-called simatic-compatible modules wrongly creates the impression that the subject advertised in periodicals, catalogs, or at exhibitions had been agreed with us. where so-called simatic-compatible modules of non-siemens manufacture are combined with our simatic automation systems, we have a case of our product being used contrary to recommendations. because of the variety of applications of our simatic automation systems and the large number of these products marketed worldwide, we cannot give a concrete description specifically analyzing the hazards created by these so-called simatic-compatible modules. it is beyond the manufacturer's capabilities to have all these so-called simatic-compatible modules checked for their effect on our simatic products. if the use of so-called simatic-compatible modules leads to defects in a simatic automation system, no warranty for such systems will be given by siemens. in the event of product liability damage due to the use of so-called simatic-compatible modules, siemens are not liable since we took timely action in warning users of the potential hazards involved in so-called simatic-compatible modules.o notes on usin g this manual and on the ce s y mbol

3-2 system manual c79000-g8576-c199-07 3.1 principles of installation of systems for emc electromagnetic compatibility (emc) is understood to mean the capability of electrical equipment to operate correctly in a defined electromagnetic environment, without being affected by the environment and without affecting the environment to an unacceptable degree. all simatic s5 products have been developed for applications in harsh industrial environments and meet high requirements for emc. before installing the control system, however, you should still carry out emc planning and involve possible interference sources in the assessment. the following chapter describes the various paths over which interference can be picked up in the plc, typical interference sources and their coupling mechanisms, basic rules for ensuring emc. 3.1.1 overview of possible types of interference electromagnetic interference can be picked up over different paths by the programmable controller: sinec bus system power supply protective conductor i/o signal lines fields programmable controller figure 3-1 electromagnetic interference with programmable controllers what does emc mean? installation guidelines
3-3 system manual c79000-g8576-c199-07 depending on the propagation medium (conducted or non-conducted interference) and distance from the source, interference can be picked up by the programmable controller via different coupling mechanisms. a distinction is made between the following: direct coupling capacitive coupling inductive coupling radiated interference installation guidelines

3-6 system manual c79000-g8576-c199-07 3.1.2 the most important basic rules for ensuring emc it is often sufficient to comply with a few elementary rules for ensuring emc. when installing the control system, therefore, observe the following five basic rules. when installing the programmable controllers, provide large-area good quality grounding of the inactive metal parts (see section 3.2). make a large-area low-impedance interconnection of all inactive metal parts. for screw connections on painted and anodized metal parts, either use special contact washers or remove the insulating protective layers. if possible, do not use aluminum parts. aluminum oxidizes easily and is therefore less suitable for grounding. make a central connection between the chassis ground and the ground/protective ground conductor system. ensure proper routing of lines when wiring (see sections 3.3.1 and 3.3.2). arrange the cabling in line groups. (ac power cable, power supply lines, signal lines, data lines) always install ac power cables and signal or data lines in separate ducts or bunches. route the signal and data lines as closely as possible to grounded surfaces such as cabinet elements, metal bars and cabinet panels. ensure that cable shields are properly secured (see section 3.3.3). data lines must be shielded. the shield should be connected at both ends. analog lines must be shielded. for the transfer of signals with low amplitudes, it may be advisable to connect the shield at only one end. provide the line shields with a large-area connection to a shield/protective conductor bar immediately after the cabinet inlet, and secure the shields with cable clamps. route the grounded shield as far as the module without interruption, but do not connect the shield there again. ensure that the shield/protective ground bar has a low-impedance connection to the cabinet. use metal or metallized connector cases for shielded data lines. installation guidelines
3-7 system manual c79000-g8576-c199-07 employ special emc measures for particular applications (see section 3.3.4). fit quenching elements to all inductances which are not controlled by simatic s5 modules. use incandescent bulbs for illuminating cabinets, and avoid fluorescent lamps. create a standard reference potential; ground all electrical apparatus if possible (see sections 3.4 and 3.5). use specific grounding measures. grounding of the control system is a protective and functional measure. system parts and cabinets with central controllers and expansion units should be connected to the ground/protective conductor system in star configuration. this serves to avoid the creation of ground loops. in the case of potential differences between system parts and cabinets, install equipotential bonding conductors of sufficient rating. installation guidelines
3-8 system manual c79000-g8576-c199-07 3.2 installation of programmable controllers for emc measures for suppressing interference voltages are often applied only when the control system is already operational and proper reception of a useful signal is impaired. the reason for such interference is usually inadequate reference potentials caused by mistakes in equipment assembly. the following sections describe: basic rules for grounding the inactive metal parts examples of cabinet assembly for emc example of rack and wall mounting for emc 3.2.1 basic rules for assembling and grounding the inactive metal parts ensure wide-area chassis grounding of the inactive metal parts when mounting the equipment. properly implemented grounding creates a uniform reference potential for the control system, and reduces the effects of picked-up interference. chassis grounding is understood to mean the electrical connection of all inactive parts. the entirety of all interconnected inactive parts is the chassis ground. inactive parts are conductive parts which are electrically isolated from active parts by basic insulation, and can only develop a voltage in the event of a fault. the chassis ground must not develop a dangerous touch voltage , even in the event of a fault. the ground must therefore be connected to the protective ground conductor. to prevent ground loops, locally separated ground elements such as cabinets, structural and machine parts, must always be connected to the protective ground system in star configuration. ensure the following when chassis grounding: connect the inactive metal parts with the same degree of care as the active parts. ensure low-impedance metal-to-metal connections, e.g. with large-area good quality contact. when you are incorporating painted or anodized metal parts in the grounding, these insulating protective layers must be penetrated. use special contact washers or remove the insulating layer. protect the connection points from corrosion, e.g. with grease. movable grounded parts such as cabinet doors must be connected via flexible grounding strips. the grounding strips should be short and have a large surface because the surface is decisive in providing a path to ground for high-frequency interference. installation guidelines
3-9 system manual c79000-g8576-c199-07 3.2.2 example of cabinet assembly for emc the example of cabinet assembly in the figure shows the various measures, the grounding of inactive metal parts and the connection of shielded cables. this example applies only to grounded operation. follow the points numbered in the figure during assembly. 2 1 7 6 5 4 8 3 figure 3-2 example of cabinet assembly for emc installation guidelines

3-14 system manual c79000-g8576-c199-07 3.3.2 equipotential bonding between separate sections of an installation, potential differences can develop if programmable controllers and i/o devices are connected via a non-floating link, or cable shields are connected at both ends and are grounded at different parts of the system. different ac supplies, for example, can cause potential differences. these differences must be reduced by installing equipotential bonding conductors to ensure functioning of the electronic components. the following points must be observed for equipotential bonding: the lower the impedance of the equipotential bonding conductor, the greater is the effectiveness of equipotential bonding. where shielded signal lines are laid between the relevant sections of the system and connected at both ends to the ground/protective conductor, the impedance of the additional equipotential bonding conductor must not exceed 10 % of the shield impedance. the cross-section of the equipotential bonding conductor must be rated for the maximum circulating current. the following cross-sections of copper have proved to be satisfactory in practice: -16 mm of copper for equipotential bonding conductors of up to 200 m in length -25 mm of copper for equipotential bonding conductors of more than 200 m in length. use copper or zinc-plated steel for equipotential bonding conductors. they must be given a large-area connection to the ground/protective conductor and protect it from corrosion. the equipotential bonding conductor should be laid so that the smallest possible areas are enclosed between the equipotential bonding conductor and signal lines. equipotential bonding conductor signal line figure 3-4 routing of equipotential bonding conductor and signal line installation guidelines
3-15 system manual c79000-g8576-c199-07 3.3.3 shielding of cables and lines shielding is a method of attenuating magnetic, electrical or electro-magnetic interference fields. interference currents on cable shields are given a path to ground via the shield bar which is electrically connected to the housing. a low-impedance connection to the protective conductor is particularly important so that these interference currents themselves do not become an interference source. where possible, only use lines with a braided shield. the coverage density of the shield should be more than 80 %. avoid lines with a foil shield because the foil can be very easily damaged by tensile strain and compression during fitting; this results in reduced effectiveness of the shield. as a rule, line shields should always be connected at both ends. this is the only way to achieve a good degree of interference suppression in the higher frequency region. only in exceptional cases should the shield be connected at one end only, as this only achieves attenuation of the low frequencies. single-ended shield connection may be more advantageous when: an equipotential bonding conductor cannot be laid; analog signals (of a few mv or a) are to be transmitted; foil (static) shields are used. as a rule, line shields should always be connected at both ends. this is the only way to achieve a good degree of interference suppression in the higher frequency region. with data lines for serial communication, always use metal or metallized connectors. secure the shield of the data line to the connector case. do not connect the shield to pin 1 of the connector. for stationary operation, it is advisable to fully strip the insulation from the shielded cable and connect it to the shield/protective conductor bar. note in the event of potential differences between ground points, a circulating current may flow through the shield connected at both ends. in this case, install an additional equipotential bonding conductor (see section 3.3.2). shields at both ends data lines installation guidelines
3-16 system manual c79000-g8576-c199-07 please observe the following points when connecting the shield: use metal cable clamps for securing the braided shield. the clamps must enclose the shield over a large area and provide a good contact. 1) connect the shield to a shield bar immediately after the cable entry into the cabinet. route the shield as far as the module but do not connect it there again. ? ? ? ? ? ? ? ?? ?? ?? ? ? ? ?? ? ? ? ?? ? ? ? ? figure 3-5 example of securing shielded lines with cable clamps 1) it is advisable to check the contacts of the screening at regular intervals. installation guidelines

3-27 system manual c79000-g8576-c199-07 note for 24 v dc digital output modules with electronic short-circuit protection, you must ensure that the reference potential of the load power supply is connected to terminal l- of the module. if this connection is missing (e.g. open-circuit), a typical current of 15 ma can flow at the outputs. this output circuit is sufficient to prevent energized contactors or relays from being released and to energize high-resistance loads (e.g. miniature relays). with floating modules the control circuit and load circuit are metallically isolated. an arrangement with floating modules is required for all ac load circuits and for dc load circuits which cannot be coupled. the reasons are, for example, different reference potentials of the sensors or grounding of the positive terminal of a battery. shown in the following figure is a simplified installation with floating modules. the arrangement is independent of the grounding concept. the connections for grounding are therefore not drawn. 1l+ 1l pe 24 v dc control power supply 2l+ 2l 24 v dc load power supply ps cpu di dq data 0 v u int l1 n 230 v ac load power supply figure 3-12 simplified representation of an arrangement with floating modules installation with floating modules installation guidelines

3-30 system manual c79000-g8576-c199-07 3.6 interference-free connection of monitors these sections cover the following topics: floating connection of cables at video inputs shielding and grounding concept information on selecting the components can be found in catalog st80. 3.6.1 interference-free connection of a monitor to the cp of the s5 controller operator control and process monitoring systems from the coros product family can be used with monitor connections. the physical arrangement of apparatus and the interference level of the environment are important for the interference-free connection of monitors to simatic s5 control systems. the choice of monitor and video cables is governed by the following: whether the monitor and plc are to be operated under low-interference conditions or under industrial conditions. where the monitor and plc are installed under low-interference environmental conditions and operated over short distances, the monitor and plc are at almost the same ground potentials. interference and ground loop disturbances are therefore not expected. in these cases, you can drive the monitor both via ttl signals and via analog signals. digital cables or single-shielded coaxial cables can be used to transmit the video signals. note that the braided shield of the coaxial cable serves as the return conductor and must not be connected to the shield bar. the monitor and communication processor (cp) are interconnected without additional shielding and grounding. where the monitor and plc are installed under harsh industrial conditions and operated over great distances, the devices may be at different ground potentials. these different ground potentials may cause interference and ground loop disturbances. operation of the monitor and plc under low-interference conditions operation of the monitor and plc under industrial conditions installation guidelines
3-31 system manual c79000-g8576-c199-07 in these cases, double-shielded coaxial cables (triaxial cables) must be used to transmit the video signals. the inner braided shield of the coaxial cable serves as the return conductor and must not be connected to the shield bar. the outer braided shield provides a path to ground for interference currents and must be incorporated in the shielding and grounding measures. to avoid ground loops, the electronics ground and housing ground of the monitor must be independent. this requirement is met when: the electronics and housing grounds of the monitor are metallically isolated, or the electronics and housing grounds are connected via a voltage-dependent resistor (vdr) fitted by the manufacturer of the monitor. 3.6.2 shielding and grounding if the monitor and plc are used under harsh industrial conditions, you must ensure the following at the plc end: cable shields should be connected to the shield bar in the cabinet, immediately after the cable inlet; - the video cables should be fully stripped; - the outer braided shield should be secured to the shield bar of the plc over as large an area as possible (e.g. with metal ties which enclose the shield or with cable clamps). shield bars should be connected to the frame or cabinet panel over a large area. shield bars should be connected to the ground point of the cabinet. you must ensure the following at the monitor end: separate the electronics ground and housing ground. - remove the jumper at the monitor to separate the two grounds. - fit touch protection at the video sockets because hazardous touch voltages of more than 40 v may be present at the sockets after separation of the grounds. connect the ground clamp of the monitor to the protective conductor. connect the cable shields to the ground clamp of the monitor; - fully strip the video cables; - secure the outer braided shield to the ground clamp of the monitor over a large area. installation guidelines

5-42 system manual c79000-g8576-c199-07 5.4 cpu 928b this section contains the hardware description and technical specifications of the cpu 928b. details on programming the cpu 928b can be found in the cpu 928b programming guide. 5.4.1 technical description you can use the cpu 928b in single and multiprocessor operation in the s5-135u/155u central controller (see chapter 6). up to four cpus can be used. the cpu 928b is universally applicable, ensuring both very fast bit processing and very fast word processing: cyclic time-controlled (9 different timebases) real-time controlled interrupt-driven (hardware interrupt) delayed (from version 6es5 928-3ub12) the programming language is step 5. the electronic circuitry of the cpu 928b is on two pcbs (basic and expansion boards) in the double eurocard format. both pcbs are screwed together, linked via connectors, and must not be separated. the basic board provides the connection to the s5 bus via two backplane connectors. the front plate width is 2 2/3 standard plug-in stations. application design cpus, memor y cards, memor y submodules, interface submodules
5-43 system manual c79000-g8576-c199-07 you require a user memory submodule (ram or eprom) for storage of your program. you can store up to 64 x 2 10 bytes of code and data blocks here. for data blocks, the cpu 928b additionally has an integrated db ram of 46 x 2 10 bytes. a description of the memory submodules can be found in sections 5.9 and 5.10; order numbers are given in the ordering information. there are two independent interfaces on the front of the cpu 928b. you can connect programmers and ops to the first interface. this pg interface si1 is permanently installed on the cpu. you can use pg interface si1 either via the front connector of the cpu 928b or via the front connector of the 923c coordinator module. note simultaneous operation of pg interface si1 via the front connector of the cpu 928b and of the coordinator is not possible. electrically, it is merely a pg interface which can be operated via two different terminals. switching the programmer online without a job request is already sufficient to operate the interface. if you wish to utilize a second pg interface for connection of a pg or op, the connection must be made via the second pg interface with the pg submodule. apart from pg interface si1, the second interface si2 can also be used as a pg interface in parallel with the first one. you can only use the second pg interface via the front connector of the pg submodule on the cpu 928b. a detailed description of operations with the two pg interfaces can be found in the cpu 928b programming guide. the connection to the pg can be established with the cpu in any operational state. user memory pg interface si1 cpus, memor y cards, memor y submodules, interface submodules
5-44 system manual c79000-g8576-c199-07 you can optionally use the second interface of the cpu 928b as: a pg interface (for pg and operator panels) interface for the rk 512 computer link interface for data transmission with procedures 3964/3964r interface for data transmission with the aopen drivero interface for data transmission via the sinec l1 bus (from version 6es5 928-3ub12). to utilize the second interface as the pg interface, you need the pg submodule. you need one of the following interface submodules for the rk 512 computer link, for data transmission with procedures 3964/3964r and for data transmission with the aopen drivero: v.24 submodule (rs 232c) tty submodule rs422 a/485 submodule (only in the rs422 a module). to utilize the second interface for data transmission via the sinec l1 bus, you need the sinec l1 submodule (from version 6es5 928-3ub12). the cpu 928b is delivered without an interface submodule. you can operate the cpu 928b without an integral interface submodule. the opening to accept a submodule in the front plate is closed by a cover. only remove the cover to fit an interface submodule. a description of interface submodules can be found in section 5.11, and the order numbers in the ordering information. a detailed description of the second interface can be found in the cpu 928b communication manual. there is an interrupt line in the plc for each cpu. it can be used when the reaction to an event must occur with higher priority than the reaction to other events. to process an interrupt, cyclic program processing is interrupted and the program stored in ob 2 (ob for interrupt processing) is inserted. (refer to the cpu 928b programming guide for further details.) this interrupt-driven program processing is only possible using an interrupt-capable digital input module or a suitable operating cp/ip module. no jumper setting on the cpu 928b is required. please note, however, that the usable interrupt line on the backplane bus depends on the cpu slot and must be set accordingly on the i/o module (see section 4.1). second interface si2 process interrupt processing cpus, memor y cards, memor y submodules, interface submodules

5-86 system manual c79000-g8576-c199-07 in this standby state of the unit the battery-backed ram submodule is in the cpu; the plc is switched off (power off); the backup battery of the plc is providing backup of the ram submodule; the submodule battery is not supplying power. note it is only possible to insert and remove the ram submodule in this state without data corruption. if the backup battery in the plc fails in this state, the submodule battery provides backup of the ram submodule. this prevents loss of data. in this standby state of the submodule the ram submodule has been removed from the cpu; the submodule battery is providing backup of the ram submodule; the contents of the battery-backed ram are retained. the battery of the battery-backed ram submodule is monitored. when the ram submodule goes to normal operation (battery-backed ram is in the cpu, supply voltage of the plc is switched on), the battery monitor on the submodule detects the following faults: submodule battery is not present. submodule battery is faulty (voltage less than 2.6 v). the red battery fault led on the front of the submodule is continuously lit. note a temporary voltage drop of the submodule battery in the standby state, for example, caused by storage below 0 o c or a battery change, is not detected by the battery monitor if the voltage dip is corrected by plugging in the ram submodule and switching on the plc. however, the voltage dip may have led to a loss or corruption of ram submodule data. standby operation submodule standby battery monitoring and battery fault cpus, memor y cards, memor y submodules, interface submodules
5-87 system manual c79000-g8576-c199-07 before the ram submodule with battery backup is started for the first time, you must insert the battery provided. this is delivered separately to protect it from premature discharge. proceed according to the following steps: step action 1 open the upper side of the cover by releasing the snap-on catch. grasp the cover within the clearance from the pcb and pull it up. 2 insert the submodule battery and secure it with a screw on the left and on the right. ensure correct polarity (+/-). 3 close the cover again. battery m 2.5 screw grip battery fault led figure 5-10 mounting location for backup battery ! caution improper replacement of the battery can result in explosion hazard. it should only be replaced by the same type or an equivalent one recommended by the manufacturer. used batteries should be disposed of according to the manufacturer's instructions. inserting or replacing the backup battery cpus, memor y cards, memor y submodules, interface submodules

6-2 system manual c79000-g8576-c199-07 6.1 introduction the s5-135u/155u is a member of the simatic s5 family of programmable (logic) controllers. the plc can be used both in single and in multiprocessor operation with up to four cpus. you can arbitrarily combine the cpus in the central controller at the cpu slots. cpu slot requirement cpu 948/cpu 928b/cpu 928 2 slots cpu 922, 928-3ua21, 928-3ub21, 948-3ua13, 948-3ua23 1 slot in multiprocessor operation, each cpu processes its individual user program independently of the other cpus. the common s5 bus serves for data interchange with i/o modules, cps, ips and other cpus. in multiprocessor operation, access of the cpus to the s5 bus is controlled by a coordinator. the functioning of this module is described in sections 6.5 and 6.6. for an explanation of data interchange between cpus in multiprocessor operation and the arrangement of your step 5 program, please consult the programming guide for your cpu. a coordinator is required in multiprocessor operation. the following exist for the s5-135u/155u plc: 923a coordinator (cor a) (is no longer supplied) and 923c coordinator (cor c). the coordinator allocates to the cpus the time divisions in which they can access the s5 bus (bus enable time), and contains the global memory for data interchange between the cpus via communication flags. additionally, the cor c contains another memory with four pages for the amultiprocessor communicationo function as well as a serial pg interface with pg multiplexer function (pg mux). slots occupied coordinator multiprocessor operation/coordinators
6-3 system manual c79000-g8576-c199-07 6.2 starting the multiprocessor operation this section guides you through the installation and startup of multiprocessor operation; the following is assumed: you are familiar with the use and programming of individual modules in single-processor operation. if this is not the case, please consult the relevant chapters in this manual and in the appropriate programming guides. note as soon as a coordinator is inserted in the s5-135u/155u central controller, all cpus are automatically in multiprocessor operation irrespective of the number of inserted cpus. even if the coordinator is only operated with one cpu, the conditions for multiprocessor operation apply to this cpu (db 1 required, dx 0 possibly required, etc.). you can use up to four cpus in the s5-135u/155u programmable controller. the permissible slots are indicated in chapter 4. startup can be subdivided into the following steps: step action 1 set the number of cpus (inserted from the left) on the coordinator. 2 if you use communication flags on cps: mask out the communication flag areas on the coordinator. 3 insert the cpus and the coordinator in the slots provided in the central controller. the cc must be disconnected from system voltage. 4 switch on the system voltage and power switch on the power supply unit. 5 execute an overall reset on all cpus. 6 load your step 5 user programs in all cpus (including db 1, additionally dx 0 for the cpu 948). 7 execute a reset on all cpus. 8 set the mode switch of the coordinator from the stop to run or test setting. procedure, overview multiprocessor operation/coordinators

6-14 system manual c79000-g8576-c199-07 ! warning since, in the test mode, no cpu can emit a basp (output inhibit) in the event of a fault, the test mode must be switched to the inactive state without fail after completion of startup to avoid a critical or even hazardous system state. before you can go into the test mode with the test switch, you have to enable it on the module. this is achieved differently with the 923a and 923c coordinators. insert jumper 3 - 14 on coding socket ep 45 as shown in the following sketch. 14 16 8 9 13 ep 45 923a coordinator set dil switch s1.3 from off to on (the following table shows the dil switches as delivered; see also figure 6-2). dil s. on off effect s1.1 s1.2 s1.3 s1.4 s1.5 s1.6 x x x x x x test mode no. of occupied cpu slots = 2 no. of occupied cpu slots = 3 no. of occupied cpu slots = 4 when the coordinator mode switch is set from stop to test, the cpus can be started individually. there is therefore no synchronized transition to cyclic program processing. the output of signal basp is suppressed on all cpus, even if there is an error. if an error occurs with a cpu switched to run, only this one goes to the stop state in the test mode. the error is indicated by slow flashing of the cpu's stop led. the error at this cpu does not affect other cpus. if the test mode is not activated, a changeover from stop to test does not result in any reaction of the cpus. test mode enabling the test mode with the 923a enabling the test mode with the 923c reaction of the cpus multiprocessor operation/coordinators

8-3 system manual c79000-g8576-c199-07 a digital input module converts the process signals to the internal signal level in the module. interference is suppressed by the input circuitry, and the logic states at the inputs are indicated with leds on the front strip of the module. with most digital input modules (except the 420), the signals are isolated from the central ground point when received. inputs relating to the same group are isolated from inputs of another group, but not from each other. the control signals processed in the plc are output via digital output modules at a signal level suitable for the actuator, for example contactor, solenoid valve, etc. for the voltages and currents required in the process, modules with appropriate output circuitry are available. with most digital output modules (except the 441), the signals are isolated from the central ground point when relayed to the outputs. outputs relating to the same group are isolated from outputs of another group, but not from each other. if a digital output module receives a acommand output inhibito (basp, cf. programming guide and chapter 4) from the cpu, the outputs are set to zero. when the supply voltage of the central controller or expansion unit has been switched on or when the cpu is at stop, the outputs are set to zero. signal output h+ on digital output modules for direct voltage emits a signal when a short-circuit to ground (l-) or overcurrent has been detected at one or more outputs currently at logic 1. only short-circuits which are effective for more than 0.5 to 1 s are detected. short-circuits are only detected at connected outputs. the signal outputs are decoupled by diodes. up to 16 outputs can be connected in parallel. ensure that isolation is not defeated by the parallel connection of outputs. to ensure functioning of the signal output, you must connect terminal 1l+ to 24 v on the 441, 451 and 454 modules. on the 453 and 457 modules, the floating signal output must be powered separately. digital input modules digital output modules basp signal output, short-circuit detection di g ital input/output modules

8-5 system manual c79000-g8576-c199-07 8.1.2 function of the enable inputs the digital input/output modules have an enable circuit. you can use the enable inputs to implement electrical interlocks for certain modules or switch off individual modules, whilst the plc is in operation. this means that: the module can no longer be addressed by the user program. all outputs of digital output modules are set to zero. modules which are switched off can be removed or inserted during operation. if this is not necessary, operate the module with the enable input switched off. on digital input/output modules with dc voltage inputs or outputs, the enable circuit requires that enable inputs f+ and f- be wired in the front connector. enabling is achieved by applying an external voltage to inputs f+/f-. modules for ac voltage have a wire jumper in the front connector. when the front connector is swivelled away from the front strip of the module, the supply of power to the enable input is interrupted, i.e. the wire jumper in the front connector is removed; the module is switched off and can no longer be addressed by the user program. when the front connector is swivelled away, i.e. the voltage is removed from the enable inputs, a timeout (qvz) occurs at the cpu (see the programming guide for the particular cpu). apart from the 6es5 458-4uc11 digital output module, all digital input/output modules additionally offer the facility for changing the enable mode. the modules have a jumper accessible from above in the vicinity of the addressing switch (see figure 8-2). enable jumper figure 8-2 location of the enable jumper jumper inserted: enable input (f+/f-) active (factory setting) jumper open: enable input (f+/f-) switched off with an active enable input di g ital input/output modules
8-6 system manual c79000-g8576-c199-07 if removal and insertion of modules during operation is not required, you must remove the plug-in jumper for changeover of the enable mode. wiring of the enable inputs (f+/f-) can then be dispensed with. almost power-free shutdown of individual subprocesses, i.e. outputs of various modules can be operated from a common load supply and yet activated separately. the load voltage of each individual module can be monitored without additional circuitry. any reactions to failure of the load voltage can be programmed in the qvz (timeout) organization block. you must observe the following when configuring systems: switching on at the latest 100 ms after power-up of the plc, the voltage must be present at the enable inputs of the i/o modules. switching off when the plc has been switched off, the voltage at the enable inputs of the i/o modules must still be present as long as voltage is applied to the cc/eu. you should observe the following instructions for switching off plcs and equipment for supplying power to the enable inputs: 24 v supply for cc/eu and i/os f+ l+ i/o modules 24 v dc b) a) cc/eu l+ battery 24v power supply enable supply from: a) battery b) terminals for 24 v on the front plate of the power supply with enable input switched off examples of functioning of the enable inputs di g ital input/output modules
8-7 system manual c79000-g8576-c199-07 when there is a need to switch off the load power supply separately without affecting the enabling of modules, there are the following possibilities for producing the enable voltage. these exist even when the power supply is used without an additional capacitor and common shutdown. 230 v ac supply for cc/eu and load power supply f+ l+ i/o modules 230v ac cc/eu -951 a) c) b) battery l+ power supply load power supply 24v enable supply from: a) 6es5 951-4lb11 load power supply b) battery c) terminals for 24 v on the front plate of the power supply proper functioning is ensured if the 24 v load power supply has an output capacitance of at least 4700 f per 10 a of load current. other units (load power supply for 20 or 40 a) which do not meet this condition can be adapted to this requirement by connecting a 10000 f/40 v capacitor in parallel. 10000 m f/ 40v cc/eu f+ l+ 230v ac i/o modules load power supply 24v power supply separate or common shutdown of the cc/eu and load power supply common shutdown of the cc/eu and load power supply with a 230 v ac supply di g ital input/output modules
8-8 system manual c79000-g8576-c199-07 8.1.3 special features of the 432 digital input module the 432 digital input module accepts 32 process signals and emits a process alarm if the logic state at one of its inputs changes. you can operate the module in the following modes: without process alarm (anormalo digital input module) with initiation of a process alarm via interrupt with initiation of a process alarm via ib 0 (only in conjunction with cpu 948) to operate the module with process alarm via ib 0, you must address it in the normal (p) area from byte 128 because the automatic updating of the process image might acknowledge a process alarm without the system program having detected and interpreted this alarm; only modules addressed in the normal (p) area can initiate a process alarm via ib 0. the time for reaction of the module to a process alarm is mainly determined by the input circuitry. you can set the reaction time to one of the values 0.3 ms, 1 ms or 3 ms with switch s5. note that the filtering effect decreases with shorter reaction times, and interference may be received as useful signals (effect of the line length, see the technical specifications). to operate the module without process alarm, you can insert it at any slot for i/o modules and address it in the entire i/o area. if you address it in the area pb/py 0 to pb/py 124, it will be within the automatic updating of the process image. make the following settings on the module to operate it without process alarm: step action 1 open jumpers x3 and x4 2 set switch rows s1 and s2 to off s1 3 3 bit 3 ir-d 4 4 bit 4 ir-e 5 5 bit 5 ir-f 6 6 bit 6 ir-g 7 7 bit 7 int 0 0 bit 0 ir-a 1 1 bit 1 ir-b 2 2 bit 2 ir-c :off :on s2 figure 8-3 switch settings for operation without process alarm the setting for switch row s3 is arbitrary in this mode. modes reaction time operation without process alarm settings on the module di g ital input/output modules
8-9 system manual c79000-g8576-c199-07 to operate the 432 digital input module with process alarm via an interrupt, you must either operate it in the cc where only certain slots have interrupt lines (see chapter 4), or in an interrupt-capable eu connected to the cc with im 307 - im 317 interfacing (see also the im 307 - im 317 manual). in the cc, you may only operate the module in this mode at slots with an interrupt line (interrupt source). so that the module can initiate a process alarm for a change of logic state, the alarm must be processed by an alarm routine (alarm ob) in the user program, with automatic acknowledgement of the alarm. to avoid loss of an alarm, it must not be possible for the alarm ob to be interrupted by process alarms. the cpu must process the process alarms with level triggering (see programming guide of the cpu). example: program the following operations in the corresponding alarm ob: l pw132 (load i/o word) t fw10 (transfer flag word) l pw134 etc. t fw12 only the flag word may be accessed during the cyclic program. accessing the i/o bytes in the process image will result in alarm loss. addressing of the module must therefore be above address 127. double accessing of i/o bytes, even from different cpus, is not permissible (alarm loss). the four i/o bytes of a module must be scanned successively and in ascending order. the scanning of byte n inhibits all input circuits of the module, and the scanning of byte (n + 3) enables them again. make the following settings on the module to operate it with a process alarm via interrupt: step action 1 open jumper x4 and close jumper x3. 2 set the interrupt line at switch row s1: the switch relating to the desired interrupt line should be set to on. set all other switches to off. you can set the same interrupt line on several modules. 3 set switch row s2 to off. 4 set switch row s3 to choose whether the interrupt is to be initiated with a positive-going (leading) or negative-going (trailing) edge. the setting of a pair of switches applies to an entire byte. operation with process alarm via interrupt scanning the process inputs settings on the module di g ital input/output modules

8-12 system manual c79000-g8576-c199-07 you can use up to eight 432 digital input modules with process alarm via ib 0 in one plc. the modules must all be inserted in the cc or in the same eu for error-free acknowledgement of address 0. each module reserves one bit in ib 0. you must set one module to bit 0 on switch row s2; on the other modules you must remove jumper x3 and set one of the other bits 2 to 8. the module you have set to bit 0 is known as the master, and the other modules are slaves. on the master module, you must additionally set the number of slave modules on switch row s2. refer to the labeling on the module cover. you can also use the 432 digital input module with process alarm together with other alarm-generating modules. to operate the module with process alarm via interrupt, you must observe the following: if a process alarm is generated via an interrupt, the i/o words of all 432 digital input modules involved in this process alarm must be read in the alarm-processing ob; with ips, the process alarms must be acknowledged (refer to the manuals of the ips). the modules must be inserted at interrupt-capable slots (see chapter 4). to operate the module with process alarm via ib 0, you must observe the following: you may use up to eight alarm-generating modules. the modules must all be inserted in the cc or all in the same eu. you must operate the 432 module as the master. if you use two or more 432 digital input modules with other alarm-generating modules, you must operate one 432 as the master and all others as slaves. 8.1.4 special features of the di/dq 482 the di/dq 482 digital input/output module (6es5482-4ua11) is a process signal i/o module which allows the processing of process signals in conjunction with the ip 257, with the s5-135u/155u plc and the eu 185u (see the ip 257 manual). the di/dq 482 (6es5482-4ua20) has an identical functionality, but not an interface which allows a connection to the ip257. the following section describes the operation of the di/dq 482 without ip 257 . the di/dq 482 has 32 channels which are jointly isolated, i.e. there is no subdivision into groups in the module. channels 0.0 to 0.7 are digital outputs, channels 2.0 to 3.7 are digital inputs; channels 1.0 to 1.7 can be optionally and individually operated as inputs or outputs. using two or more 432 digital input modules with process alarm via ib 0 using the 432 digital input module with other alarm- generating modules di g ital input/output modules
8-13 system manual c79000-g8576-c199-07 the operation of channels 1.0 to 1.7 as inputs or outputs merely depends on the user program. you define the byte as an input with a read access to the di/dq; you define the byte as an output with a write access. the double-function of the byte also allows the output byte to be read out. unused channels should not be wired nor addressed by program. when these channels are used as inputs, it should be noted that the corresponding bits in the output register remain at logic 0. this resetting of output registers is executed automatically after power-up of the plc or eu. note when at least one of channels 1.0 to 1.7 is operated as an input, the connected sensors and the 1l+ terminal must have the same power supply. if this is not the case, the input voltage acts on the 1l+ terminal. the resultant supply to the output amplifiers of channels 0.0 to 1.7 causes currents to be drawn via the wired input terminal; these currents may assume different values, depending on the control states of the outputs. with the di/dq 482 (6es5482-4ua11) you must set slide switch s2 to setting 1 for operation without the ip 257. local bus interface slide switch s2 figure 8-6 slide switch s2 on the di/dq 482 changeover of the i/o byte di g ital input/output modules

8-26 system manual c79000-g8576-c199-07 external quenching circuitry is needed when the switching frequency of an output is greater than that specified in the technical specifications (thermal stress of the integrated circuit for quenching inductive loads); disconnection of output lines can be expected; disconnection of the supply line can be expected. when selecting or designing the quenching circuitry, the technical specifications for the digital output should be taken into account. these are: the permissible overvoltage for the supply voltage (see section 8.3 acommon technical specificationso) inductive breaking voltage of the output (see section 8.4 adescription of individual moduleso) an external quenching circuit only provides thermal relief if its quenching voltage is lower than the breaking voltage specified for the module, allowing for unfavorable supply voltage conditions. example: 453 digital output inductive breaking voltage l+ - 47 v (tech. specifications) max. supply voltage l+ = 30 v quenching voltage referred to l- (0 v ground) is - 17 v the quenching device must be rated at approximately 15 v and the switched load current, for example, 1 a. a quenching device rated for the induced breaking current must be provided at the load (see figure 8-14). the quenching voltage at the load is independent of the module. the quenching devices must also ensure that the overvoltages at the switch and in the wiring do not exceed the disturbance voltage and voltage hazard limits permissible to vde/iec. the following applies to digital outputs for dc voltage: in general, load power supplies should be switched on the primary side to utilize the low-resistance secondary winding and smoothing capacitors of the power supply for energy compensation in the dropping of inductive loads. the load power supply switch should only be considered as a circuit breaker. with switched-through digital outputs and disconnection of the supply line l+, the output current is maintained during the quenching time by capacitors and the reverse voltage protection diode on the module. this severe electrical stress of the module should be avoided during operations, because it can result in a fault in the long term. external quenching circuitry switching frequency of the output is higher than the permissible value disconnecting the load circuit disconnecting the supply line l+ and l switched-through outputs di g ital input/output modules
8-27 system manual c79000-g8576-c199-07 with two-wire switches and ac voltage outputs: disconnection of the supply voltage during operation is not permissible without additional protective circuitry. quenching of the inductive load is achieved here via the load power supply unit or system. since, as two-wire switches, the outputs have no l-/n (0 v ground) terminal, the inductive load cannot be quenched on the module when the supply line is disconnected. with the 453 and 457 modules using two-wire switches, the overvoltages can result in destruction of the module. if the load voltage must be switched for safety reasons, you must provide external quenching circuitry at each inductive load (see figure 8-15). instead, with the 453 and 457 modules using two-wire switches, you can insert a quenching device (diode) with adequate ratings after contact k from the l+ line to l-. digital output dc voltage digital output ac voltage l+ l n l- contact, switch contactor, solenoid valve, etc. quenching device (diode, zener diode, r/c network or varistor) common diode only on 453/457 elr elr elr figure 8-15 quenching of inductive loads when switching the supply line l+ and l two-wire switches di g ital input/output modules

9-5 system manual c79000-g8576-c199-07 the enable circuit requires an external 24 v voltage at enable inputs f+/f- in the front connector. if there is no voltage at f+/f-, the modules will not acknowledge. when the front connector is swivelled away from the front strip of the module, the supply of power to the enable input is interrupted, i.e. the module is switched off and can no longer be addressed by the user program: a timeout (qvz) occurs in the cc. the 460 module additionally offers the facility for changing the enable mode. the module has a jumper accessible from above in the vicinity of the addressing switch. when the enable jumper is inserted, you can define the behaviour of the 460 analog input module as follows: when the enable voltage and load voltage are obtained from the same load supply, a shutdown of the 24 v load voltage will result in a timeout. when the enable voltage and load voltage are obtained from different load supplies, a shutdown of the 24 v load voltage will not result in a timeout. (with the 460-4ua11/12 modules, a shutdown of the load voltage will result in a timeout.) enable jumper figure 9-2 enable input and enable jumper jumper inserted: enable input (f+/f-) active (factory setting) jumper open: enable input (f+/f-) switched off examples of functioning of the enable inputs: to switch off individual subprocesses, i.e. outputs of various modules can be operated from a common load supply and yet activated separately. the load voltage of individual modules can be monitored without additional circuitry. any reactions to failure of the load voltage can be programmed in the qvz (timeout) organization block. enable input switching off the enable input analo g input/output modules

9-8 system manual c79000-g8576-c199-07 9.3.3 special features of the 460 analog input module the 460 analog input module executes integrating processing of the digital input signals; periodic system interference is thus suppressed. you can adapt the process signals, according to the application, to the input level of the analog-to-digital converter of the module with plug-in range cards (resistor dividers or shunt resistors). to monitor the sensors connected to the inputs, you can use the 6es5 498-1aa11 range card (through-connection card) to implement the abroken wire detectiono mode. you can activate broken wire detection for 4 or 8 inputs. each time the input value is about to be encoded, a constant current is briefly (1.6 ms) switched to the input terminals and the resultant current is checked for a limit value. if a digital voltmeter is used to measure the signal at the input, these current pulses may appear to indicate fluctuation of the signal. the encoded value, however, is not affected. if these apparent fluctuations of the signal are disturbing, for example, during startup, you can switch the tripping current to the inactive state on the 460 analog input module: apply + 24 v to pin 24 of the front connector, and 0 v to l-. you must additionally set the mode switch to awithout broken wire detection.o in the event of open-circuit of the sensor or its line, the voltage exceeds the limit and a broken wire is indicated (bit 1 in data byte 1). the analog-to-digital converter encodes the value 0. a broken wire signal is only useful when the 6es5 498-1aa11 through-connection card is used. with all other measurement cards, a broken wire signal will result in incorrect reactions. further details relating to the broken wire signal can be found in section 9.3.12. if the measuring range is exceeded, the overflow bit (bit 2 0 of the low byte) is set. you have a choice of the cyclic sampling and selective sampling modes. in the cyclic sampling mode, the module continuously encodes all measured values. the digitized measured values are stored under the channel-related address on the module (the high byte under this address, and the low byte under the next higher address). the measured values can then be read by the module at any time without waiting. when you operate the module in this mode, you can set a module address from 0 to 255. broken wire signal switching the tripping current to the inactive state measuring range exceeded cyclic sampling analo g input/output modules
9-9 system manual c79000-g8576-c199-07 in the selective sampling mode, a measured value is encoded on the central initiative of the cpu. at the start of conversion, the module must be addressed once with a write operation (t pw) by the user program. an active bit (t = 1) is set during encoding. with the transition to t = 0, the measured value becomes valid. with non-constant cycle times, there may be non-periodic measured value aquisition. if you operate the module in this mode, you must set a module address from 128 to 255. you can also use the address range from 0 to 127 for selective sampling after appropriate programming in db 1 of the user program. another method is that of time-controlled program processing. with this method, certain program segments (e.g. fb 13) are automatically inserted into program processing at the 100 ms rate by a time-controlled block (ob 13). a constant timebase is thus achieved. fb 13 sprm-b len=22 abs sheet 1 segment 1 name: selsampl example of selective sampling 0005 : 0006 : 0007 :l pw128 read analog value 0008 :t mw128 in to aux: flag fw 128 0009 :a m 129.2 scan activity =1? 000a :jc = end if = 1, jump to end 000b :t fw10 if = 0, measured value in fw 10 000c :t pb128 initiate sampling 000d end : (1st value invalid after start) 000e 000f : 0010 :be you can read analog values of analog input modules with a function block from the abasic functionso package. the basp signal is not interpreted by the 460 analog input module. selective sampling time-controlled program processing function block basp (output inhibit) analo g input/output modules

9-12 system manual c79000-g8576-c199-07 however, analog input modules and analog output modules may be given the same address with cyclic sampling because they are distinguished by the user program. this is not possible with selective sampling. for cyclic sampling, you can address the module in the address range from 0 to 255, and for selective sampling from 128 to 255. for selective sampling, you can also use the address range from 0 to 127 after appropriate programming in db 1 of the user program. example: on an analog input module with start address 160 (ib 160 = input byte 160), input channel 3 is to be scanned by the program. step action 1 affix the self-adhesive label with address 160 on the free field under the addressing switch on the module. adb 5 and adb 7 are marked on the label. 2 press the appropriate rockers of the addressing switch down on the side marked by a dot on the module cover. set the other rockers to the opposite setting. this way sets the start address of the module. adb 5 and adb 7 results in 2 5 + 2 7 = 32 + 128 = 160 3 enter the address 160 + 3 x 2 = 166 in the program for input channel 3. addressing for cyclic/selective sampling analo g input/output modules

9-54 system manual c79000-g8576-c199-07 9.5.3 special features of the 465 analog input module the 465 analog input module executes integrating processing of the digital input signals; periodic system interference is thus suppressed. you can adapt the process signals, according to the application, to the input level of the analog-to-digital converter of the module with plug-in range cards (resistor dividers or shunt resistors). to monitor the sensors connected to the inputs, you can use the 6es5 498-1aa11 range card (through-connection card) to implement the abroken wire detectiono mode. you can activate broken wire detection for 8 or 16 inputs in 16-channel operation, and for 4 or 8 inputs in 8-channel operation. each time the input value is about to be encoded, a constant current is briefly (1.6 ms) switched to the input terminals and the resultant current is checked for a limit value. if a digital voltmeter is used to measure the signal at the input, these current pulses may appear to indicate fluctuation of the signal. the encoded value, however, is not affected. if these apparent fluctuations of the signal are disturbing, for example, during startup, you can switch the tripping current to the inactive state on the 465 analog input modules: apply + 24 v to pin 24 of the front connector, and 0 v to l-. you must additionally set the mode switch to awithout broken wire detection.o in the event of open-circuit of the sensor or its line, the voltage exceeds the limit and a broken wire is indicated (bit 1 in data byte 1). the analog-to-digital converter encodes the value 0. a broken wire signal is only useful when the 6es5 498-1aa11 through-connection card is used. with all other measurement cards, a broken wire signal will result in incorrect reactions. further details relating to the broken wire signal can be found in section 9.5.10. if the measuring range is exceeded, the overflow bit (bit 2 0 of the low byte) is set. you have a choice of the cyclic sampling and selective sampling modes. in the cyclic sampling mode, the module continuously encodes all measured values. the digitized measured values are stored under the channel-related address on the module (the high byte under this address, and the low byte under the next higher address). the measured values can then be read by the module at any time without waiting. when you operate the module in this mode, you can set a module address from 0 to 255. broken wire signal switching the tripping current to the inactive state measuring range exceeded cyclic sampling/ selective sampling analo g input/output modules
9-55 system manual c79000-g8576-c199-07 in the selective sampling mode, a measured value is encoded on the central initiative of the cpu. at the start of conversion, the module must be addressed once with a write operation (t pw) by the user program. an active bit (t = 1) is set during encoding. with the transition to t = 0, the measured value becomes valid. with non-constant cycle times, there may be non-periodic measured value aquisition. if you operate the module in this mode, you must set a module address from 128 to 255. you can also use the address range from 0 to 127 for selective sampling after appropriate programming in db 1 of the user program. another method is that of time-controlled program processing. with this method, certain program segments (e.g. fb 13) are automatically inserted into program processing at the 100 ms rate by a time-controlled block (ob 13). a constant timebase is thus achieved. fb 13 sprm-b len=22 abs sheet 1 segment 1 name: selsampl example of selective sampling 0005 : 0006 : 0007 :l pw128 read analog value 0008 :t fw128 in to aux: flag 128 0009 :s f 129.2 scan activity=1? 000a :jc = end if = 1, jump to end 000b :t fw10 if = 0, measured value in fw 10 000c :t pb128 initiate sampling 000d end : (1st value invalid after start) 000e 000f : 0010 :be you can read analog values of analog input modules with a function block from the abasic functionso package. the basp signal is not interpreted by the 460 analog input module. time-controlled program processing function block basp (output inhibit) analo g input/output modules

9-58 system manual c79000-g8576-c199-07 however, analog input modules and analog output modules may be given the same address with cyclic sampling because they are distinguished by the user program. this is not possible with selective sampling. for cyclic sampling, you can address the module in the address range from 0 to 255, and for selective sampling from 128 to 255. for selective sampling, you can also use the address range from 0 to 127 after appropriate programming in db 1 of the user program. example: on an analog input module with start address 160 (ib 160 = input byte 160), input channel 3 is to be scanned by the program. step action 1 affix the self-adhesive label with address 160 on the free field under the addressing switch on the module. adb 5 and adb 7 are marked on the label. 2 press the appropriate rockers of the addressing switch down on the side marked by a dot on the module cover. set the other rockers to the opposite setting. this way the start address of the module is set. adb 5 and adb 7 results in 2 5 + 2 7 = 32 + 128 = 160 3 enter the address 160 + 3 x 2 = 166 in the program for input channel 3. addressing for cyclic/selective sampling analo g input/output modules

9-107 system manual c79000-g8576-c199-07 the enable circuit requires an external 24 v voltage at enable inputs f+/f- in the front connector. if there is no voltage at f+/f-, the modules will not acknowledge. when the front connector is swivelled away from the front strip of the module, the supply of power to the enable input is interrupted, i.e. the module is switched off and can no longer be addressed by the user program: a timeout (qvz) occurs in the cc. the -4ux12/13-type modules additionally offer the facility for changing the enable mode. the modules have a jumper accessible from above in the vicinity of the addressing switch. enable jumper figure 9-38 enable input and enable jumper jumper inserted: enable input (f+/f-) active (factory setting) jumper open: enable input (f+/f-) switched off examples of functioning of the enable inputs: to switch off individual subprocesses, i.e. outputs of various modules can be operated from a common load supply and yet activated separately. the load voltage of individual modules can be monitored without additional circuitry. any reactions to failure of the load voltage can be programmed in the qvz (timeout) organization block. enable input switching off the enable input analo g input/output modules
9-108 system manual c79000-g8576-c199-07 you must observe the following when configuring systems: switching on at the latest 100 ms after power-up of the plc, the voltage must be present at the enable inputs of the i/o modules. switching off when the plc has been switched off, the voltage at the enable inputs of the i/o modules must still be present as long as the internal 5 v voltage is present. however, you must ensure that the 24 v load supply for analog output modules is switched off together with the plc. if the supply voltage is still present at the modules and the plc is switched off, the output values can drift. (the analog holding elements for the outputs will no lon- ger be refreshed with the current value, because there is no 5 v supply to the modules from the bus.) you should observe the following instructions for switching off ccs and equipment for supplying power to the enable inputs. when there is a need to switch off the load power supply separately without affecting the enabling of modules, there are the following possibilities for producing the enable voltage. these exist even when the load power supply is used without an additional capacitor and common shutdown. 230 v ac supply for cc/eu and load power supply f+ l+ i/o modules 230 v ac cc/eu -951 a) c) b) battery l+ power supply load power supply 24v supply for the enable inputs from: a) 6es5 951-4lb11 load power supply b) battery c) terminals for 24 v on the front plate of the power supply configuring switching off the cc separate or common shutdown of the cc/eu and load power supply analo g input/output modules

9-112 system manual c79000-g8576-c199-07 however, analog input modules and analog output modules may be given the same address with cyclic sampling because they are distinguished by the user program. this is not possible with selective sampling. for cyclic sampling, you can address the module in the address range from 0 to 255, and for selective sampling from 128 to 255. for selective sampling, you can also use the address range from 0 to 127 after appropriate programming in db 1 of the user program. example: on an analog output module with 8 outputs with start address 144 (ib 144 = output byte 144), output channel 7 is to be scanned by the program. step action 1 affix the self-adhesive label with address 160 on the free field under the addressing switch on the module. adb 4 and adb 7 are marked on the label. 2 press the appropriate rockers of the addressing switch down on the side marked by a dot on the module cover. set the other rockers to the opposite setting. this sets the start address of the module. adb 4 and adb 7 results in 2 4 + 2 7 = 16 + 128 = 144 3 enter the address 144 + 7 x 2 = 158 in the program for input channel 7. addressing for cyclic/selective sampling analo g input/output modules

b-2 system manual c79000-g8576-c199-07 b.1 what is esd? all electronic modules are equipped with large-scale integrated ics or components. due to their design, these electronic elements are very sensitive to overvoltages and thus to any electrostatic discharge. these e lectrostatically- s ensitive d evices are commonly referred to by the abbreviation esd . electrostatically-sensitive devices are labeled with the following symbol: ! caution electrostatically-sensitive devices are subject to voltages that are far below the voltage values that can still be perceived by human beings. these voltages are present if you touch a component or the electrical connections of a module without previously being electrostatically discharged. in most cases, the damage caused by an overvoltage is not immediately noticeable and results in total damage only after a prolonged period of operation. definition guidelines for handlin g electrostaticall y -sensitive devices ( esd )

b-4 system manual c79000-g8576-c199-07 b.3 general protective measures against electrostatic discharge damage make sure that the personnel, working surfaces, and packaging are sufficiently grounded when handling electrostatically-sensitive devices. you thus avoid electrostatic charging. you should touch electrostatically-sensitive devices only if it is unavoidable (for example, during maintenance work). hold modules without touching the pins of components or printed conductors. in this way, the discharged energy cannot affect the sensitive devices. if you have to carry out measurements on a module, you must discharge your body before you start the measurement by touching grounded metallic parts. use grounded measuring devices only. ensure sufficient grounding avoid direct contact guidelines for handlin g electrostaticall y -sensitive devices ( esd )
