similar safety measures in external circuits (i.e., not in the programmable controller) must be provided by the customer . ? always use the power supply voltage specified in the operation manuals. an incorrect voltage may result in malfunction or burning. ? take appropriate measures to ensure that the specified power with the rated voltage and frequency is supplied. be particularly careful in places where the power supply is unstable. an incorrect power supply may result in malfunction. ? install external breakers and take other safety measures against short-circuit - ing in external wiring. insuf ficient safety measures against short-circuiting may result in burning. ? do not apply voltages to the input units in excess of the rated input voltage. excess voltages may result in burning. ? do not apply voltages or connect loads to the output units in excess of the maximum switching capacity . excess voltages or loads may result in burning. ? disconnect the functional ground terminal when performing withstand voltage tests. not disconnecting the functional ground terminal may result in burning. ? install the unit properly as specified in the operation manual. improper installa - tion of the unit may result in malfunction. ? be sure that all the mounting screws, terminal screws, and cable connector screws are tightened to the torque specified in the relevant manuals. incorrect tightening torque may result in malfunction. ? use crimp terminals for wiring. do not connect bare stranded wires directly to terminals. connection of bare stranded wires may result in burning. ? double-check all the wiring before turning on the power supply . incorrect wir - ing may result in burning. ? be sure that the terminal blocks, memory units, expansion cables, and other items with locking devices are properly locked into place. improper locking may result in malfunction. ? check the user program for proper execution before actually running it on the unit. not checking the program may result in an unexpected operation. ? confirm that no adverse ef fect will occur in the system before attempting any of the following. not doing so may result in an unexpected operation. ? changing the operating mode of the pc. ? force-setting/force-resetting any bit in memory. ? changing the present value of any word or any set value in memory. ? resume operation only after transferring to the new cpu unit the contents of the dm area, hr area, and other data required for resuming operation. not doing so may result in an unexpected operation. ? do not pull on the cables or bend the cables beyond their natural limit. doing either of these may break the cables. ? do not place objects on top of the cables. doing so may break the cables. 6 conformance to ec directives the cv -series pcs that comply with ec directives must be installed as follows: 1, 2, 3... 1. the cv -series pcs are designed for installation inside control panels. the pc must be installed within a control panel. 2. use reinforced insulation or double insulation for the dc power supplies to be connected to the dc i/o units for cv500-ps211. use separate power supplies as the external power supplies for the relay output units and the power supplies for the dc i/o units. 3. to meet the ec directives (low v oltage directive), the maximum switching capacity while the cv500-ps211 is being operated is 24 vdc/2 a. 6 conformance to ec directives xv 4. pcs complying with ec directives also conform to the common emission standard (en50081-2). when a pc is built into a machine, however , noise can be generated by switching devices using relay outputs and cause the overall machine to fail to meet the standards. if this occurs, surge killers must be connected or other measures taken external to the pc. the following methods represent typical methods for reducing noise, and may not be sufficient in all cases. required countermeasures will vary depending on the devices connected to the control panel, wiring, the config - uration of the system, and other conditions. countermeasures refer to en50081-2 for more details. countermeasures are not required if the frequency of load switching for the whole system including the pc is less than 5 times per minute. countermeasures are required if the frequency of load switching for the whole system including the pc is 5 or more times per minute. countermeasure examples when switching an inductive load, connect a surge protector , diodes, etc., in par - allel with the load or contact as shown below. circuit current characteristic required element ac dc cr method power supply inductive load yes yes if the load is a relay or solenoid, there is a time lag between the moment the circuit is opened and the moment the load is reset. if the supply voltage is 24 or 48 v, insert the surge protector in parallel with the load. if the supply voltage is 100 to 200 v, insert the surge protector between the contacts. the capacitance of the capacitor must be 1 to 0.5 m f per contact current of 1 a and resistance of the resistor must be 0.5 to 1 w per contact voltage of 1 v. these values, however, vary with the load and the characteristics of the relay. decide these values from testing, and take into consideration that the capacitance suppresses spark discharge when the contacts are separated and the resistance limits the current that flows into the load when the circuit is closed again. the dielectric strength of the capacitor must be 200 to 300 v. if the circuit is an ac circuit, use a capacitor with no polarity. diode method power supply inductive load no yes the diode connected in parallel with the load changes energy accumulated by the coil into a current, which then flows into the coil so that the current will be converted into joule heat by the resistance of the inductive load. this time lag, between the moment the circuit is opened and the moment the load is reset, caused by this method is longer than that caused by the cr method. the reversed dielectric strength value of the diode must be at least 10 times as large as the circuit voltage value. the forward current of the diode must be the same as or larger than the load current. the reversed dielectric strength value of the diode may be two to three times larger than the supply voltage if the surge protector is applied to electronic circuits with low circuit voltages. varistor method power supply inductive load yes yes the varistor method prevents the imposition of high voltage between the contacts by using the constant voltage characteristic of the varistor. there is time lag between the moment the circuit is opened and the moment the load is reset. if the supply voltage is 24 or 48 v, insert the varistor in parallel with the load. if the supply voltage is 100 to 200 v, insert the varistor between the contacts. --- 6 conformance to ec directives xvi when switching a load with a high inrush current such as an incandescent lamp, suppress the inrush current as shown below. out com r out com r countermeasure 1 providing a dark current of approx. one-third of the rated value through an

factory computer, down through the pcs, and then on down through the network to the i/o devices: control components like the switches, stepping motors, solenoids, and sensors which monitor and control mechanical operations. pc pc pc pcs process control computer factory computer i/o devices a control system can involve very large applications where many dif ferent mod - els of pc are networked together or it could be an application as small as a single pc controlling a number of output devices. 1-2 the role of the pc the pc is the part of the control system that directly controls the manufacturing process. according to the program stored in its memory, the pc accepts data from the input devices connected to it and uses this data to monitor the con- trolled system. when the program calls for some action to take place, the pc sends data to the output devices connected to it to cause that action to take place. the pc may be used to control a simple, repetitive task, or it may be con - nected to other pcs or to a host computer in order to integrate the control of a complex process. the role of the pc section 1-2 3 1-2-1 input devices pcs can receive inputs from either automated or manual devices. the pc could receive data from the user via a pushbutton switch, keyboard, or similar device. automated inputs could come from a variety of devices: micro-switches, timers, encoders, photoelectric sensors, and so on. some devices, like the limit switch shown below , turn on or off when the equipment actually makes contact with them. other devices, like the photoelectric sensor and proximity sensor shown below, use other means, such as light or inductance, in order to get information about the equipment being monitored. photoelectric sensor limit switch proximity sensor 1-2-2 output devices a pc can output to a myriad of devices for use in automated control. almost any - thing that you can think of could be controlled by a pc. some of the most com - mon devices are motors, solenoids, servomotors, stepping motors, valves, switches, indicator lights, buzzers, and alarms. some of these output devices, such as the motors, solenoids, servomotors,

solenoid servomotor stepping motor the role of the pc section 1-2 4 1-3 pc operation pcs operate by monitoring input signals and providing output signals. when changes are detected in input signals, the pc reacts through the user-pro- grammed internal logic to produce output signals. the pc continually executes the program in its memory to achieve this control. block diagram of pc power supply input output cpu memory programming device signals from switches, sensors, etc. signals to solenoids, motors, etc. a program for your applications must be designed and stored in the pc. this program is then executed as part of the cycle of internal operations of the pc. execution cycle when a pc operates, i.e., when it executes its program to control an external system, a series of operations are performed inside the pc. these internal oper - ations can be broadly classified into the following four categories. refer to the cv-series pcs operation manual: ladder diagrams for details. 1, 2, 3... 1. common (or overseeing) processes, such as watchdog timer operation and testing the program memory. 2. data input and output. 3. program execution. 4. peripheral device servicing. cycle time the total time required for a pc to perform all these internal operations is called the cycle time. timing is one of the most important factors in designing a control system. for accurate operations, it is necessary to have answers to such questions as these: w how long does it take for the pc to execute all the instructions in its memory? w how long does it take for the pc to produce a control output in response to a given input signal? pc operation section 1-3 5 the cycle time of the pc can be automatically calculated and monitored, but it is necessary to have an understanding of the timing relationships within the pc for effective system design and programming. refer to the cv -series pcs opera - tion manual: ladder diagrams for details on internal pc processing and to the cvss operation manuals for details on monitoring the cycle time. 1-4 cv-series manuals the following manuals are available for the various cv -series products. other manuals are also available for

used to create networks and enable remote i/o are intro - duced in this section. refer to the operation manuals for the systems for details. the sysmac net link system is a lan (local area network) for use in factory automation systems. the sysmac net link system can consist of up to 128 nodes among which communications may be accomplished via datagrams, data transfers, or automatic data links. datagrams transmit and receive data using a command/response format. com - mands can be issued from the user program by the deliver command in- struction (cmnd(194)). data can also be transmitted and received using the network send and network receive (send(192)/recv(193)) instructions in the user pro- gram. up to 256 words of data can be transferred for each instruction. automatic data links allow pcs and computers to create common data areas. sysmac net link unit cv500-snt31 up to 4 units can be mounted. cv-series cpu rack/expansion cpu rack line server center power feeder c200h c500 c1000h c2000h personal computer note up to four sysmac net link units (cv500-snt31) can be mounted to the cpu rack and/or expansion cpu rack of each cv-series pc. sysmac net link system networks and remote i/o systems section 1-6 8 sysmac link system networks can also be created using sysmac link systems. a sysmac link system can consist of up to 62 pcs, including the cv500, cv1000, cv2000, cvm1, c200h, c1000h, and c2000h. communications between the pcs is ac - complished via datagrams, data transfers, or automatic data links in ways simi - lar to the sysmac net link system. the main dif ferences between sysmac net link and sysmac link systems is in the structure of automatic data links and in the system configuration, e.g., only pcs can be linked in sysmac link systems, whereas other devices can form nodes in sysmac net link systems. datagrams transmit and receive data using a command/response format. com - mands can be issued from the user program by the deliver command in- struction (cmnd(194)). data can also be transmitted and received using the network send and network receive (send(192)/recv(193)) instructions in the user pro- gram. up to 256 words of data can be

applicable to all cv500-cpu01-e and cv1000-cpu01-e cpus with lot numbers in which the rightmost digit is 3 ( 3) or higher. 1, 2, 3... 1. the mlpx(110) (4-to-16 decoder) instruction has been improved to also function as a 8-to-256 decoder and the dmpx(1 1 1) (16-t o-4 encod - er) instruction has been improved to also function as a 256-to-8 encoder . to enable this improvement, the digit designator (di) has been changed as shown below. specifies the first digit to be converted 4-to-16/16-to-4: 0 to 3 8-to-256/256-to-8: 0 or 1 number of digits to be converted 4-to-16/16-to-4: 0 to 3 (1 to 4

0000 processing y: enable multiple usage (default) n: disable multiple usage improved specifications section 1-9 13 3. the operation of completion flags for timers has been changed so that the completion flag for a timer turns on only when the timer instruction is executed with a pv of 0000 and not when the timer ' s pv is refreshed to a pv value of 0000, as was previously done. only the timing of the activation of the completion flag has been changed, and the timer ' s pv is still refreshed at the same times (i.e., when the timer instruction is executed, at the end of user program execution, and every 80 ms if the cycle time exceeds 80 ms). 4. the read(190) (i/o read) and writ(191) (i/o write) instructions have been improved so that they can be used for special i/o units on slave racks under the following conditions. a) the lot number of the remote i/o master unit and remote i/o slave unit must be the same as or latter than the following. 1992 october (y : november; z: december) 1st 01 x 2 b) the dip switch on the remote i/o slave unit must be set to a54mh.o c) the special i/o unit must be one of the following: ad101, ct012, ct021, ct041, asc04, ids01-v1, ids02, ids21, ids22, or ldp01-v1. (the nc221-e, nc222, cp131, and fz001 cannot be mounted to slave racks.) 1-9-2 version-1 cpus cv-series cpus were changed to version 1 from december 1993. the new model numbers are as follows: cvm1-cpu01-ev1, cvm1-cpu11-ev1, cv500-cpu-ev1, cv1000-cpu-ev1, and cv2000-cpu-ev1. (of these, all cvm1 cpus were changed to version 2 from december 1994; refer to the next sections for details.) the following additions and improvements were made to create the version-1 cpus. pt link function the host link interface on the cpu can be used to connect directly to program - mable t erminals (pt s) to create high-speed data links. t o use the pt links, turn on pin 3 of the dip switch on the cpu. pin 3 must be turned off for host link connections. eeprom writes with the new cpus, you can write to eeprom memory cards mounted to the cpu by using the file write operation from a peripheral device. a memory card writer is no longer required for this write operation. w riting is possible in pro - gram mode only. new command a new i/o register command (qq) has been added so that words from dif fer- ent data areas can be read at the same time. faster host links the communications response time for the built-in host link interface on the cpu has been improved by a factor of approximately 1.2. faster searches the search speed from peripheral devices for instructions and operands has been nearly doubled. 1-9-3 version-2 cvm1 pcs cvm1 cpus were changed to version 2 and a new cpu was added from de- cember 1994. the new model numbers are as follows: cvm1-cpu01-ev2, cvm1-cpu11-ev2, and cvm1-cpu21-ev2. improved specifications section 1-9 14 the following additions and improvements were made to create the version-2 cpus. cmp/cmpl new versions of the cmp(020) and cmpl(021) have been added that are not intermediate instructions. the new instructions are cmp(028) and cmpl(029) and are programs as right-hand (final) instructions. a total of 24 other new com - parison instructions have also been added with symbol mnemonics (e.g., >, +, and <). xfer(040) this instruction has been upgraded so that source and destination areas can overlap. dmpx(111) this instruction has been upgraded so that either the msb or the lsb can be specified for use as the end code. previously only the the msb could be used. new flags underflow and overflow flags have been added at a50009 and a50010, re- spectively. these flags can be turned on or off when executing adb, adbl, sbb, and sbbl and can be saved or loaded using ccl and ccs. new instructions a total of 125 new instructions have been added. these instructions are sup- ported by version-2 cpus only. faster online editing the time that operation is stopped for online editing has been reduced and is no longer added to the cycle time. the following are just a couple of examples. edit time operation is stopped adding or deleting one instruction block at the beginning of a 62k-word program approx. 0.5 s deleting an instruction block containing jme from the beginning of a 62k-word program approx. 2.0 s the above speed increase also applies to all v1 cpus with lot numbers in which the rightmost digit is 5 ( 5) or higher. new host link commands new c-mode commands for the cpu host interface have been added and the functionality of existing commands has been improved as follows: new commands w rl/wl: read and write commands for the cio area. w rh/wh: read and write commands for the cio area. w cr: read command for the dm area. w r#/r$/r%: sv read commands. w w#/w$/w%: sv change commands. w *: initialization command. improved commands w the link area (cio 1000 to cio 1063) and holding area (cio 1200 to cio 1299) can now be specified for the ks, kr, kc, and qq commands. w cvm1-cpu21-ev2 can now be read for the mm command. the above new and improved commands can also be used with all v1 cpus with lot numbers in which the rightmost digit is 5 ( 5) or higher. note only the following programming devices support version-2 cpus: sss (c500-zl3at1-e) and the cvm1-prs21-ev1 programming console (cvm1-mp201-v1). of these, the sss does not support sfc and thus cannot be used for the cv500, cv1000, and cv2000. use the cvss for these pcs. improved specifications section 1-9 15 section 2 system configuration and components this section provides information about the types of system configuration in which the cv -series pcs can be used and the individual units that make up these configuration. refer to appendix a standar d models for a list of c- and cv -series prod -

sified into five different types of configuration. ? systems with only a cpu rack ? systems with only cv-series expansion i/o racks. ? systems with an expansion cpu rack. ? systems with a single cv-series expansion i/o rack. ? systems with c500 expansion i/o racks. if only a cpu rack is used, an i/o control unit is not required, but the cpu rack is otherwise the same as those in the following examples. the specific units used in the configuration are described in more detail later. the maximum i/o capacity with any configuration is 512 points (32 words) for the cv500 or cvm1-cpu01-ev2; 1,024 points (64 words) for the cv1000 or cvm1-cpu11-ev2; and 2,048 points (128 words) for the cv2000 or cvm1-cpu21-ev2. the i/o capacity will be less depending on the racks and the types of units mounted. the following figure shows an assembled cv -series cpu rack and seven ex - pansion i/o racks. up to seven expansion i/o racks may be connected in one or two series from the cpu rack. the total length of i/o connecting cable must be 50 m or less for each series and a t ermination resistance unit must be be connected to the last rack or to the unused i/o control unit connector. units can be mounted to any slot on the racks shown for them below. i/o control unit: cv500-ic201/ic101 cpu: cv500-cpu01-ev1, cv1000-cpu01-ev1, cv2000-cpu01-ev1, cvm1-cpu01-ev2, cvm1-cpu11-ev2, or cvm1-cpu21-ev2 cpu backplane: cv500-bc031/051/101 power supply unit: cv500-ps221/ps21 1 or cvm1-p a208 i/o interface unit cv500-ii201 i/o backplane cv500-bi042/062/112 power supply unit cv500-ps221/ps211 or cvm1-p a208 3, 5, or 10 slots sysmac net link units sysmac link units sysmac bus/2 masters personal computer units basic units c500 i/o units c500 special i/o units sysmac bus masters i/o connecting cable cv500-cn 2 (50 m max. total length for 1 series) 4/6/11 slots c500 i/o units c500 special i/o units sysmac bus masters t ermination resistance unit: cv500-ter01 (t wo included with cv500-ic101/201 i/o control unit.) systems with only cv-series expansion i/o racks system configuration section 2-1 17 when nine or more cpu bus units (temperature controller data link units, sysmac net link units, sysmac link units, sysmac bus/2 remote i/o master units, ethernet units, basic units, and personal computer units) are required in a system, the cpu rack may be extended by connecting an expan - sion cpu rack to enable mounting up to 16 cpu bus units. only one expansion cpu rack may be connected to a cpu rack. a system that includes an expansion cpu rack can be extended by connecting up to six ex - pansion i/o racks. the expansion i/o racks may be connected in one or two series from the cpu rack. the total length of i/o connecting cable must be 50 m or less for each series and a termination resistance unit must be con- nected to the last rack or to the unused i/o control unit connector. using an expansion cpu rack does not increase the maximum i/o capacity of the pc; it only increases the number of cpu bus units that can be used. units can be mounted to any slot on the racks shown for them below. cpu backplane: cv500-bc031/051/101 power supply unit: cv500-ps221/ps21 1 or cvm1-pa208 cpu connecting cable cv500-cn 1 expansion cpu back- plane cv500-bi1 11 power supply unit: cv500-ps221/ps21 1 or cvm1-p a208 i/o connecting cable cv500-cn 2 (50 m max. total length for 1 series) t ermination resistance unit cv500-ter01 (t wo included with cv500-ic101/201 i/o control unit.) i/o backplane cv500-bi042/062/112 4/6/11 slots c500 i/o units c500 special i/o units sysmac bus masters i/o interface unit cv500-ii101 i/o interface unit (cv500-ii201) i/o control unit: cv500-ic101 cpu: cv500-cpu01-ev1, cv1000-cpu01-ev1, cv2000-cpu01-ev1, cvm1-cpu01-ev2, cvm1-cpu1 1-ev2, or cvm1-cpu21-ev2 3, 5, or 10 slots sysmac net link units sysmac link units sysmac bus/2 masters personal computer units basic units c500 i/o units c500 special i/o units sysmac bus masters 11 slots sysmac net link units sysmac link units sysmac bus/2 masters personal computer units basic units c500 i/o units c500 special i/o units sysmac bus masters power supply unit: cv500-ps221/ps21 1 or cvm1-p a208 systems with an expansion cpu rack system configuration section 2-1 18 when only one expansion i/o rack is required, a simplified system configura -

configuration section 2-1 23 2-2 racks this section describes the racks used to construct a pc system. the individual components used to construct the racks are described in the next section. 2-2-1 cpu racks the following figure shows the parts of the cpu rack. there are five back- planes available for the cpu rack. any cpu can be mounted to any backplane. the only dif ferences in the backplanes is the number of slots that they provide for units, their expansion capability , and the number of slots for cpu bus units. the cv500-bc031, cv500-bc051, and cv500-bc101 provide complete ex- pansion capability and provide 3, 5, and 10 slots, respectively, for units other than the cpu, power supply unit, and i/o control unit. the cvm1-bc053 and cvm1-bc103 do not support i/o control units and pro - vide 5 and 10 slots, respectively , for units other than the cpu and power supply unit. because i/o control units are not supported, these backplanes can be connected only to a single expansion i/o

rack components section 2-3 27 cpu indicators the following table describes the indicators on the front panel of the cpu. indicator operation power (green) lights when power is supplied to the cpu. run (green) lights when the pc is operating normally. error (red) lights when an error in the cpu causes operation to stop. when the error indicator lights, the run indicator will go out and all outputs from output units will be turned off. wdt (red) lights when a cpu error (watchdog timer error) has been detected. when the wdt indicator lights, the run indicator will go out and all outputs from output units will be turned off. alarm (red) lights when non-fatal error is detected. outinh (orange) lights when the output off bit (a00015) is turned on to turn off pc outputs. comm (orange) lit from when data is received from the host computer until the response is completed. dip switch settings the dip switch is used to set certain basic operational parameters for the cpu. to gain access to the dip switches, open the cover of the memory card com- partment as shown in the following figure. t urn of f power to the pc before setting the dip switch. off on 123456 on pin function 6 specifies whether the termination resistance is connected for the host link system. turn this pin on to connect the terminal resistance. when rs-422 is used set this pin to on at the last pc connected in the host link system. when rs-232c is used, this pin does not affect host link system operation and may be set to either on or off. 5 to transfer the user program file (autoexec.obj) and the pc setup (autoexec.std) from the memory card to the cpu on power application, set this pin to on. if this pin is set to off, the pc setup can be changed from the cvss so that only the user program (autoexec.obj) is transferred when power is turned on. if program transfer is designated both with this pin setting and in the pc setup, then both the program file and the pc setup will be transferred. the user program will not be transferred when the system protect keyswitch on the front panel of the cpu is set to the system protect position, or memory is write-protected from the cvss. 4 set this pin to the on position to establish the following communications settings for the host link interface. these are the most common setting for an ibm pc/at interface. baud rate: 9,600 bps unit number: 0 parity: even data length: 7 bits stop bits: 2 when this pin is off, the communications settings for the host link interface are set in the pc setup. refer to the cvss operation manuals for details on the pc setup. note: the above settings apply to cpus manufactured from july 1995 (lot number **75 for july 1995). for cpus manufactured before july 1995 (lot number **65 for june 1995), only 1 stop bit will be set and the baud rate will be 2,400 bps. rack components section 2-3 28 pin function 3 set this pin to on when using the host link interface with a pt using nt link

computer running cvss. memory cards memory cards can be used to store data or programs as files to expand the memory storing capacity of the pc. memory cards fit into the slot located on the lower left side of the cpu. memory cards are not provided with the pc and must be ordered separately and installed in the cpu. there are three types of memory cards that can be used for the cv-series pcs: ram, eeprom, or eprom. memory type model capacity remarks ram hmc-es641 64k bytes --- hmc-es151 128k bytes hmc-es251 256k bytes hmc-es551 512k bytes eeprom hmc-ee641 64k bytes cv500-mcw memory card

for the con - ventional memory cards. ? a 64k-byte, 128k-byte, 256k-byte, 512k-byte, 1m-byte, or 2m-byte ram that conforms to jeida4.0. the 2m-byte ram is not applicable to the cv500-mcw01 memory card writer. rack components section 2-3 29 ram and eeprom cards data can be randomly written to and read from ram or eeprom cards, making it possible to easily stored programs. the memory of a ram cards is erased, however, when power is not supplied to the cpu or when the ram card is re - moved from the cpu without first being connected to a backup battery. ee- prom cards cannot be written while mounted in the cpu. data can be written to ram cards while they are mounted in the cpu by using the cvss or by in - structions in the user program. both the ram and eeprom memory cards are equipped with write-protect switches. setting the write-protect switch to on prevents data from being written to or erased from the card. setting the write-protect switch to off allows data to be written to or erased from the card. on off four ram memory card models are available, varying in memory capacity from 8k, 16k, 32k to 64k words. t wo eeprom memory card models are available, one containing 8k words of memory and the other 16k words of memory. ram card backup battery insert a battery into a ram memory card before mounting the card into the cpu. leave the battery in its holder . battery life

during the cpu' s operation. the eprom chip is mounted to the memory card and the entire pack is installed in the cpu. once data is written to the chip, the data will not be lost when the power to the pc is off. rom cards are shipped unprogrammed. the rom card can be programmed using a cv500-mcw memory card writer. the procedure for erasing eprom memory card data is as follows: 1, 2, 3... 1. open the memory card cover by pressing at an angle on the catch at the bottom edge of the card using a pointed object, such as a pen. 2. erase the data from the eprom chips by exposing the window of the eprom chips to ultraviolet light. any of a number of commercially available eprom erasers may be used. to ensure complete erasure, the memory card should be subject to a minimum exposure as specified by the eraser manufacturer. 3. close the cover and slide the catch back into place. rack components section 2-3 30 expansion data memory an expansion data memory unit may be used only in a cv1000-cpu01-ev1, cv2000-cpu01-ev1, or cvm1-cpu21-ev2 cpu. the expansion data memory unit fits into the slot located on the upper left side of the cpu. the ex - pansion data memory unit is optional. there are three models of memory units available with dif ferent memory capacities. the addition of an expansion data memory unit increases the data memory capacity of the cv1000, cv2000, or cvm1-cpu21 from 24k words (d00000 to d24575) to up to 256k words. refer to the cv-series pc operation manual: ladder diagrams for details on pc memory and addressing conventions. model memory capacity

backplane for a cv -series pc is illustrated below. the backplane has two functions: it provides physical support for the units that are mounted to it and it provides the connectors and electrical pathways neces - sary for connecting the units. the first device we will mount to the backplane is a power supply unit. the pow - er supply unit fits into the rightmost slot on the backplane and provides electric - ity at the voltage required by the other units in the pc. it can also be used to power devices other than the pc if necessary and it enough current is available. power supply unit the cpu is mounted next to the power supply unit. the cpu fits into the posi - tion directly to the left of the power supply unit. cpu assembly section 3-1 41 the cv -series cpus have no i/o points built in. in order to complete the pc we need to mount one or more units providing i/o points to the backplane. mount the units to the backplane by pressing them firmly into position, making sure the connectors are properly mated. secure the unit by tightening the mounting screws located on the top and bottom of the unit. mounting screws provided at the top and bottom of the unit. connector make sure the connectors are properly mated. the following figure shows one i/o unit mounted directly to the left of the cpu. units other than the power supply unit, the cpu, and the i/o control unit (see below) can be mounted to any of the other slots on the cpu rack. i/o unit as you can see from the figure, there is still some space available to the left of the i/o unit. this space is for any additional units that may be required. the figure above shows a total of ten i/o units mounted to the backplane. these i/o units could be replaced by other units, such as special i/o units, cpu bus units, etc. i/o units come in five shapes; a-, b-, c-, d- and e-shape (refer to ap- pendix b specifications ) each of which can be mounted to any of the ten slots. the backplane, power supply unit, cpu, and other units are collectively called a cpu rack. assembly section 3-1 42 if we want to include more than ten units in our configuration, we can add an additional rack by mounting an i/o control unit to the leftmost slot of the cpu rack. i/o control unit now we can use a cable to connect the cpu rack to another rack. this rack has a power supply unit and i/o units mounted to it, but it has no cpu of its own. the additional rack must also have an i/o interface unit mounted to its leftmost slot to allow communications between the additional rack and the cpu rack. the backplane, power supply unit, i/o interface unit, and other units are col - lective called an expansion i/o rack or an expansion cpu rack. the differ- ences between the various types of rack and the types of systems they can be used in are described in earlier sections of this manual. a cpu rack connected to a single expansion i/o rack is shown below. i/o interface unit cpu rack expansion i/o rack the cpu rack and expansion i/o rack shown above are connected by a cable via the i/o control unit and i/o interface unit. it is possible to keep adding ex - pansion i/o racks in this way until the maximum number of i/o points for the system is reached. each expansion i/o rack requires an i/o interface unit, al - though a single expansion i/o rack can be connected by directly connecting the cpu and expansion i/o backplanes, as described in an earlier section. assembly section 3-1 43 3-1-2 memory card and expansion data memory unit extra memory is available in two forms, via the use of memory cards or by using an expansion data memory unit. this section outlines the procedure for mount - ing and removing these optional memory devices. memory cards the memory card can be used to store data and programs as files. memory cards are optional and are not supplied with the cpu. they must be ordered separately and installed by the user mount a memory card to the cpu using the following procedure. 1, 2, 3... 1. open the cover of the memory card compartment. 2. if the memory card is ram or eeprom, set the write-protect switch to off so that data can be written to the card. 3. insert the memory card into its compartment. in doing so, a slight resistance will be felt as the connector on the memory card mates with the connector on the cpu. continue pushing until the memory card is inserted completely into the cpu. if the memory card on/off switch is on, the memory card indicator will light. 4. close the cover. memory card indicator memory card on/off switch memory card eject button memory card cover removing a memory card 1, 2, 3... 1. open the cover of the memory card compartment. 2. press the memory card on/off switch once if the memory card indicator is lit. the memory card indicator will turn off. 3. press the memory card eject button. the memory card will be released al - lowing it to be removed. 4. pull out the memory card. 5. close the cover. note 1. do not expose the memory card to high temperature, humidity, or direct sunlight. 2. do not bend the card or subject it to shock. 3. do not apply excess force to the card when inserting or removing it. 4. do not remove the card while the memory card indicator is lit; doing so may result in data errors in the memory. mounting a memory card assembly section 3-1 ! 44 expansion data memory unit mount the expansion data memory unit to the cv1000 cpu using the following procedure. 1, 2, 3... 1. turn off the power to the pc. caution do not attempt to mount or remove the memory unit while the power to the pc is on. during mounting or removal, exercise care that you do not directly touch the memory elements or connector pins of the unit. hold the unit by the lever. 2. remove the expansion data memory unit cover on the front panel of the cpu by pushing the lever on the cover upwards, as indicated by the arrow on the cover. bracket screw bracket 3. loosen the bracket screw and remove the bracket. expansion data memory unit pcb guides pullout lever 4. hold the expansion data memory unit with the component side to the right, and insert the unit into the pcb guides. in doing so, a slight resistance will be felt as the connector on the memory unit mates with the connector on the cpu. continue pushing until the memory unit is inserted completely into the cpu. mounting the expansion data memory unit assembly section 3-1 ! 45 5. re-attach the bracket insert the bottom part of the bracket into the groove of the case and then press the bracket into place and tighten the bracket screw. bracket 6. attach the cover to the compartment. when the expansion data memory unit is mounted to the cpu, the expansion data memory unit is backed up by the battery in the cpu. when the unit has been removed from the cpu, the memory contents will be retained for about 10 minutes by a backup capacitor built-in to the unit, provided that cpu power was on and that the unit was mounted in the cpu for at least 1 minute. when removing the expansion data memory unit, be sure to turn on the power to the pc for more than 1 minute and then turn it off . at that time the capacitor will be fully charged allowing it to be backed up for 10 minutes. the retention period will be shorter if memory unit has been mounted (to the cpu) for less than 1 minute. 3-2 installation environment this section details the necessary environmental conditions for installing the pc. caution static electricity can damage pc components. y our body can carry an electro - static charge, especially when the humidity is low. before touching the pc, be sure to first touch a grounded metallic object, such as a metal water pipe, in order to discharge any static build-up. ambient conditions do not install the pc in any of the following locations. doing so will af fect pc life and may affect operating performance. ? locations subject to ambient temperatures lower than 0 c or higher than 55 c. ? locations subject to drastic temperature changes or condensation. ? locations subject to ambient humidity lower than 10% or higher than 90%. ? locations subject to corrosive or flammable gases. ? locations subject to excessive dust (especially iron dust) or chloride. ? locations that would subject the cpu to direct shock or vibration. ? locations that would subject the pc to water, oil, or chemical reagents. ? locations exposed to direct sunlight. cooling there are two points to consider in order to ensure that the pc does not over - heat. the first is the clearance between the racks, and the second is installation of a cooling fan. installation environment section 3-2 46 clearance between racks the racks need to have suf ficient room between each other to allow for i/o wir - ing, and additional room to ensure that the i/o wiring does not hamper cooling. the racks must also be mounted so that the total length of the connecting cable between all racks in a given series does not exceed 50 m. as a general rule, about 70 to 120 mm should be left between any two racks. consider fac - tors such as the width of the wiring duct, wiring length, ventilation, and ease of access to units, when determining the spacing between racks. greater space is required between racks when using certain cpu bus and special i/o units. refer to the operation manuals for the units you are using for details. cooling fan a cooling fan is not always necessary , but may be needed in some installations. try to avoid mounting the pc in a warm area or over a source of heat. a cooling fan is needed if the ambient temperature may become higher than that speci- fied. if the pc is mounted in an enclosure, install a cooling fan, as shown in the following diagram, to maintain the ambient temperature within specifications. pc fan louver 3-3 mounting racks each rack must be mounted vertically , that is, with the printing on the front pan - els oriented as it would normally read. racks may be directly mounted to any sturdy support meeting the environmental specifications. whenever possible, use wiring conduit to hold the i/o wiring. standard wiring conduit should be used, and it should be long enough to completely contain the i/o wiring and keep it separated from other cables. mounting racks section 3-3 47 the duct work shown in the following diagram is not used for mounting the racks. although optional, this duct work can be used to house the wires from the i/o units that run along the sides of the racks, keeping the wires from becoming entangled. this figures illustrate the correct way to mount the racks. input duct cpu rack expansion i/o rack fuses, relays, timers (do not install heat-gen - erating equipment or power equipment.) terminal blocks for pc t erminal blocks for power equipment power

racks must also be con - nected to a power source via a power supply unit. if possible, use independent power sources for the racks, input devices, and output devices. supply power to the cpu rack and expansion cpu rack from the same power source. if supplied by separate sources or if power is not supplied to the expan - sion cpu rack, the cpu will not operate. it is also recommended that power to the expansion i/o racks be supplied from the same power source as the cpu and expansion cpu racks. in order to supply power to the expansion i/o racks from separate power sources, turn on the power to the expansion i/o racks be - fore turning on power to the cpu rack. supply power to the various parts of the system (power equipment, controls, pc system, and dc i/o, etc.) via separate power supplies. power supply units section 3-4 ! ! 51 3-4-1 wiring the power source the following diagrams show the proper way to connect the power source to the power supply unit. the terminals marked anco

line ground terminal to the ground (gr: ) terminal to improve noise resistance. to avoid electrical shock, attach a grounded a wg 14 wire (cross-sectional area of 2 mm 2 ) to the ground terminal. the ground resistance must be 100 or less and must be checked periodically to be sure that environmental conditions have not deteriorated ground capacity. do not use a wire longer than 20 m. power supply units section 3-4 ! ! 54 pc operation may be adversely af fected if the ground wire is shared with other equipment or if the ground wire is attached to the metal structure of a building. when using expansion i/o racks, the racks must also be grounded to the ground terminal. the same ground can be used for all racks. screw (3.5 mm head with self-raising pressure plate) for grounding use 2 mm 2

(low-voltage directives). start input the st ar t input terminals are short-circuited at the factory with a short bar . the short bar can be removed and the terminals wired to a 10-ma, 24-vdc external input to control pc operation. when these terminals are open, pc operation will stop. run output the run output terminals will be on (closed) when the pc is operating in run or monit or mode. these terminals can thus be wired to provide an external signal indicating the operating status of the pc, such as is used in the emergen - cy stop circuit in the next section. power supply units section

recheck all wiring before supplying power to the system. note the run output on slave racks will go off when a remote i/o error occurs. power supply units section 3-4 57 3-4-4 emergency stop you can use an external relay (cr in the following figure) to form an emergency stop circuit that shuts down the system when pc operation stops. this can be achieved by wiring the run output from the power supply unit on the cpu rack as shown below. mcb1 mcb2 cr1 power supply control section dc voltage regulator transformer or noise filter twisted-pair wires pc run output + dc input/output cr1 surge suppressor pc 3-4-5 power interruptions a sequence circuit is built into the pc to handle power interruptions. this circuit prevents malfunctions due to momentary power loss or voltage drops. a timing diagram for the operation of this circuit is shown below. power supply power interrup - tion detection signal program execution momentary power interruption flag (a40202) cpu reset signal run output * 0.3 to 1 ms for dc power . 85% power interruption power interruption detection time: 10 to 25 ms* shutdown processing momentary power inter - ruption time (default: 0 ms) initialization normal normal stops standby power retention time: 10 ms (fixed) power off interrupt program power-on interrupt program power supply units section 3-4 ! 58 the pc ignores all momentary power interruptions if the interruption lasts no longer than 10 ms. if the interruption lasts between 10 and 25 ms, the interrup - tion may or may not be detected. if the supply voltage drops below 85% of the rated voltage for longer than 25 ms (less for the dc power supply unit), a power interruption detection signal is output and program execution is halted. if power is not restored within 10 ms (the power retention time) after the power interruption detection signal is output, the pc stops operating and all outputs are turned off. if after power interruption detection, power is restored within a period defined as the momentary power interruption time (default value: 0 ms), the cpu will re- sume operation. if the momentary power interruption time elapses and power has not been restored, the cpu will begin execution of the power off interrupt program if one has been programmed. the cpu stops operating after the lapse of the power retention time (10 ms). note the momentary power interruption time can be set to between 0 and 10 ms. for details, refer to the cvss operation manuals . caution if a c500 expansion i/o rack is connected to the pc, the momentary power in - terruption time setting is not ef fective and a power interruption of any length will trigger shut down processing. automatic recovery operation is resumed automatically when the voltage is restored to more than 85% of the rated value. 3-4-6 current consumption the power supply units are limited in the total current they can supply to units on the racks. the following table shows the maximum current available on a rack for either model of power supply unit. the available current shown in the table is in addition to the current consumed by the backplane, power supply unit, cpu, i/o control unit, i/o interface unit, and peripheral devices. rack cv500-ps221/211 cvm1-pa208 cpu rack cv500 or cvm1-cpu01-ev2 9.8 a max. 5.8 a max. cv1000, cv2000, cvm1-cpu11-ev2, or cvm1-cpu21-ev2 9.4 a max. 5.4 a max. expansion cpu rack 11 a max. 7 a

cpu, i/o control unit, i/o interface unit, remote i/o slave units, and peripher - al devices (the power requirements for these units have already been allowed for). the total must not exceed the limit given above for the rack. the current consumption for the expansion i/o rack does not include the cur - rent consumed by peripheral devices. the current consumed by peripheral devices attached to the expansion i/o rack must be included when calculating the total current consumption. power supply units section 3-4 59 input units units model consumption (a) dc input 3g2a5-id112 0.01 3g2a5-id114 0.34

3-5 62 3-5-1 terminal blocks the terminal block of an i/o unit can be removed by loosening the mounting screws. y ou do not have to remove the lead wires from the terminal block in or - der to remove the block from an i/o unit. terminal block mounting screws loosen the terminal block mounting screws to remove the terminal block from the i/o unit. make sure the mounting screws on the terminal block are tightened af - ter wiring is complete and the terminal block is re- mounted to the i/o unit. 3-5-2 wiring precautions general electrical noise take appropriate measures when any electrical device likely to produce noise is connected to the pc as a load. devices generating noise of more than 1,200 v (such as electromagnetic relays and valves) require noise suppression. for noise sources running on dc power , connect a diode in parallel with the coil of each device. when mounting a cpu rack and an expansion i/o rack together on a mounting plate, provide a ground to the mounting plate. the mounting plate must be plated with a highly conductive surface in order to ensure noise immunity. wiring i/o units section 3-5 63 when an inductive load is connected to an i/o unit, connect a surge suppressor or diode in parallel with the load, as shown in the following diagram. the diode will adsorb the back electromagnetic field generated by the load. l in com diode dc input out com relay

output devices and output units can be damaged if the load connected to an output terminal is shorted. attach a fuse to the output circuit to protect your sys - tem. a fuse is recommended even if the output unit is provided with an internal fuse (e.g., t ransistor and t riac output units), to increase easy of maintenance and provide extra protection. interlock circuits when the pc controls an operation such as the clockwise and counterclockwise operation of a motor , provide an external interlock such as the one shown below to prevent both the forward and reverse outputs from turning on at the same time. pc mc2 mc1 00501 00502 mc1 mc2 motor clockwise motor counterclockwise interlock circuit this circuit prevents outputs mc1 and mc2 from both being on at the same time. even if the pc is programmed improperly or malfunctions, the motor is pro - tected. output leakage current if a transistor or triac output unit is used to drive a low voltage load, the leakage current may prevent the output device from turning off. to prevent this, con- nect a bleeder resistor in parallel with the load as shown in the following table. pc load power supply out com bleeder resistor l r select the

when connecting a t ransistor or t riac output unit to an output device having a high surge current (such as an incandescent lamp), care must be taken to avoid damage to the output unit. the t ransistor and t riac output units are capable of withstanding a surge current of ten times the rated current. if the surge current for a particular device exceeds this amount, use one of the following circuit con - figurations to protect the output unit. out com l r + the above circuit protects the output unit by letting the load draw a small current (about one third the rated current) while the output is off , significantly reducing the surge current. the following circuit reduces the surge current by employing a current-limiting resistor. l out com + r a transistor output unit's output cannot be directly connected to a ttl input because of the transistor's residual voltage. when connecting ttl circuits to transistor output units, connect a pull-up resistor and a cmos ic between the two. 3-5-3 wiring examples the following examples illustrate how to connect i/o devices to i/o units. during wiring, work slowly and carefully. if an input device is connected to an output unit,

the following precautions must be abided by when installing cv -series pcs to meet ec directives. 1, 2, 3... 1. cv-series pcs are classified as open-structure devices and must be installed inside a control panel. 2. use reinforced insulation or double insulation on the dc power supply con - nected to cv500-ps211 power supply unit and dc i/o units. 3. use separate power supplies for relay output units and dc i/o units. compliance with ec directives section 3-6 67 4. the maximum switching capacity of the cv500-ps21 1 power supply unit is 2 a at 24 vdc when complying with ec directives (low-voltage directives). 5. cv-series pcs that meet ec directives meet the common emission stan- dard (en50081-2) of the emc directives as individual products. when as - sembled into machinery, however, the noise generated by switching relay outputs can fail to meet the standard. when noise is excessive, surge killers must be installed or other measures must be taken outside of the pc. the measures required to meet the standard will vary with the load being driven, wiring, the configuration of the machinery, etc. the following examples show means of reducing noise. these means will only reduce the amount of noise and will not eliminate noise. they are pro - vided here as examples only. requirement the following conditions can be used to determine if measures to reduce noise are necessary. refer to the en50081-2 standard for details. ? if the loads of the devices into which the pc is built are switched less than 5 times a minute, then no measures need to be taken. ? if the loads of the devices into which the pc is built are switched 5 times or more a minute, then measures need to be taken. examples connect a surge suppressor or diode in parallel with the load, as shown in the following diagrams, when switching inductive loads. cr method (ac or dc) the reset time will be increased if the load is a relay , solenoid, or similar device. connect the cr between the load connections for 24-v and 48-v power supply voltages and between the contact connections for 100 to 200-v power supply voltages. the capacitor and resistors can be based on the following guidelines. c: 0.5 to 1 m f for each amp of contact current r: 0.5 to 1 w for each volt of contact voltage. you will need to adjust the above values depending on the characteristics of the load, relay , etc., based on the discharge suppression of the capacitor when the contacts are open and the current control ef fect of the resistor the next time the circuit is closed. the dielectric strength of the capacitor generally needs to be between 200 and 300 v . use an ac capacitor (without polarity) in an ac circuit. inductive load cr power supply diode method (dc only) the energy stored in the coil is impressed on the coil as a current by the action of the parallel diode and converted to joule heat by the resistance of the inductive load. here, the reset time will be increased even more than for the cr method. inductive load surge suppressor compliance with ec directives section 3-6 68 the reverse dielectric strength of the diode must be 10 times the circuit voltage and the forward current must be at least as high as that of the load. if the circuit voltage is low enough, as it is for most electronic circuits, then the reverse dielec - tric strength of the diode can be as low as 2 to 3 times the circuit voltage. inductive load power supply varistor (ac or dc) the method uses the fixed voltage characteristics of a varistor to prevent high voltages from being applied to the contacts. here, as well, the reset time will be increase somewhat. connect the varistor between the load connections for 24-v and 48-v power supply voltages and between the contact connections for 100 to 200-v power supply voltages. inductive load power supply output surge current when connecting an output device having a high surge current (such as an in - candescent lamp), use one of the following circuit configurations to protect the output unit. the following circuit lets the load draw a small current (about one third the rated current) while the output is off, significantly reducing the surge current. out com l r + the following circuit reduces the surge current by employing a current-limiting resistor. l out com + r compliance with ec directives section 3-6 69 section 4 inspection and maintenance this section describes the procedures necessary for periodic inspection and maintenance. always keep spare items on hand so that they can be used as immediate replacements. 4-1 cpu battery

simplify wiring by inputting status to up to 64 bits through only 16 points. using digital switches or a specially wired keyboard, the dif ferent combinations of input points will determine which bits are on. t wo examples of connections using digital switches or a keyboard are given. appendix b specifications 116 connection example 1 (keyboard) the wiring diagram and table below show how the id212 dc input unit can be wired using a specially wired key - board. for example, if a on the keyboard is pressed, the combination of inputs on da t a 0 and stb 9 turn on bit 00 of word n. similarly , the combination of inputs on da t a 7 and stb 7 turn on bit 15 of word n+3. the value of word n depends on where the unit is mounted. + 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 24 vdc a b c d e

wires and high-tension equipment or power lines. if this cannot be avoided, use shielded cables when wiring the dc input unit. be sure to keep the total length of the wires less than 10 m. appendix b specifications 117 connection example 2 (digital switches) this example shows how the id212 dc input unit can be wired using digital switches. just as the keys on the keyboard can turn on dif ferent combinations of bits, the digital switches can control dif ferent combinations of bits. for example, the combination of inputs on switch no. 1 and input point 00 turn on bit 00 of word n. (for the sake of simplicity, the figure below shows the digital switches wired to control 32 bits instead of 64 bits as was shown in example 1.) wire stb 4, stb 5, stb 6, and stb 7 to access an

133 wiring dynamic outputs (3g2a5-od211) by using the od21 1 dc output unit, a large number of outputs can be controlled through only 16 bits. just like the id211 dc input unit, dif ferent combinations of bits can control dif ferent outputs. using this type of unit can simplify wiring when many outputs must be controlled. up to 64 outputs can be accessed. because the output data is positive logic, a terminal output goes high when the output bit is on (1). a strobe output is negative logic, so when the output bit is on (1), the corresponding terminal goes low . use positive logic output devices for the load of this unit. the strobe output is cyclic and automatically output. 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 24 vdc 6543 1 11 7 display no. 87654321 24 k 1 w 24 k
