Conformance to EC Directives

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 Voltage Directive), the maximum switching
capacity while the CV500-PS211 is being operated is 24 VDC/2 A.
4. PCs complying with EC Directives also conform to the Common Emission
Standard (EN61000-6-4). 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 configuration of the system, and other conditions.
Countermeasures
Refer to EN61000-6-4 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
parallel with the load or contact as shown below.

load
CR method
Yes
Characteristic
Required element
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 µF per contact current of
1 A and resistance of the resistor must
be 0.5 to 1 Ω 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.

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.

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

The varistor method prevents the impo- --sition 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.

Control Systems
1-1
Control Systems
A Control System is the electronic equipment needed to control a particular
process. It may include everything from a process control computer, to the
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.

I/O devices
A Control System can involve very large applications where many different
models 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
controlled 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 connected to other PCs or to a host computer in order to integrate the control of a complex process.

Section 1-2
The Role of the PC
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: microswitches, 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
Proximity Sensor
Limit Switch
1-2-2
Output Devices
A PC can output to a myriad of devices for use in automated control. Almost
anything that you can think of could be controlled by a PC. Some of the most
common 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, stepping motors, and
valves, affect the controlled system directly. Others, such as the indicator
lights, buzzers, and alarms, provide outputs to notify personnel operating or
monitoring the system.

PC Operation

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-programmed internal logic to produce output signals. The PC continually executes the program in its memory to achieve this control.

Programming
Device
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
operations 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:
• How long does it take for the PC to execute all the instructions in its memory?
• How long does it take for the PC to produce a control output in response
to a given input signal?
4
Section 1-4
CV-series Manuals
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
Operation Manual: Ladder Diagrams for details on internal PC processing and
to the CVSS Operation Manuals for details on monitoring the cycle time.

Networks and Remote I/O Systems
Systems that can be used to create networks and enable remote I/O are introduced in this section. Refer to the operation manuals for the Systems for
details.
SYSMAC NET Link System
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.
Commands can be issued from the user program by the DELIVER COMMAND instruction (CMND(194)).
Data can also be transmitted and received using the NETWORK SEND and
NETWORK RECEIVE (SEND(192)/RECV(193)) instructions in the user program. 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 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 accomplished via datagrams, data transfers, or automatic data
links in ways similar to the SYSMAC NET Link System.
The main differences 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.
Commands can be issued from the user program by the DELIVER COMMAND instruction (CMND(194)).
Data can also be transmitted and received using the NETWORK SEND and
NETWORK RECEIVE (SEND(192)/RECV(193)) instructions in the user program. Up to 256 words of data can be transferred for each instruction.

I/O System
Remote I/O can be enabled by adding a SYSMAC BUS/2 Remote I/O System
to the PC. The SYSMAC BUS/2 Remote I/O System is available in two types:
optical and wired.
Two Remote I/O Master Units, optical or wired, can be mounted to the CV500
or CVM1-CPU01-EV2 CPU Rack or Expansion CPU Rack. Four Remote I/O
Master Units can be mounted to the CV1000, CV2000, or CVM1-CPU11/21EV2 CPU Rack or Expansion CPU Rack.
Up to eight Remote I/O Slave Racks can be connected per PC.
Slaves can be used to provide up to 1,024 remote I/O points for the CV500 or
CVM1-CPU01-EV2; up to 2,048 remote I/O points for the CV1000, CV2000,
or CVM1-CPU11/21-EV2. These limits are the totals for all Slaves control by
one PC.
A Programming Device (such as the CVSS) can be connected to up to two
Remote I/O Slave Units for each Remote I/O Master Unit as long as a total of
no more than four Programming Devices are connected per PC.

Improved Specifications
Upgraded Specifications
The following improvements are 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(111) (16-TO-4 ENCODER) 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.
Digit number: 3
2 1 0
0
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 digits)
8-to-256/256-to-8: 0 or 1 (1 or 2 digits)
Process
0: 4-to-16/16-to-4
1: 8-to-256/256-to-8
2. The following operating parameter has been added to the PC Setup.
JMP(004) 0000 Processing
Y: Enable multiple usage (default)
N: Disable multiple usage
14
Section 1-9
Improved Specifications
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.
01
X
2
1992
October (Y: November; Z: December)
1st
b) The DIP switch on the Remote I/O Slave Unit must be set to “54MH.”
c) The Special I/O Unit must be one of the following: AD101, CT012,
CT021, CT041, ASC04, IDS01-V1, IDS02, IDS21, IDS22, or LDP01V1. (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 Programmable Terminals (PTs) to create high-speed data links. To 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. Writing is possible in
PROGRAM mode only.
New Command
A new I/O REGISTER command (QQ) has been added so that words from different 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.

Section 1-9
Improved Specifications
1-9-3
Version-2 CVM1 PCs
CVM1 CPUs were changed to version 2 and a new CPU was added from
December 1994. The new model numbers are as follows: CVM1-CPU01-EV2,
CVM1-CPU11-EV2, and CVM1-CPU21-EV2.
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 comparison 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 MSB could be used.
New Flags
Underflow and Overflow Flags have been added at A50009 and A50010,
respectively. 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 supported 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
Adding or deleting one instruction block at the
beginning of a 62K-word program
Deleting an instruction block containing JME from
the beginning of a 62K-word program
Time operation is stopped
Approx. 0.5 s
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
• RL/WL: Read and write commands for the CIO Area.
• RH/WH: Read and write commands for the CIO Area.
• CR: Read command for the DM Area.
• R#/R$/R%: SV read commands.
• W#/W$/W%: SV change commands.
• *: Initialization command.
Improved Commands
• 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.
• 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.
16
Section 1-9
Improved Specifications
Note Only the following Programming Devices support version-2 CPUs: SSS
(C500-ZL3AT1-E) and the CVM1-PRS21-EV1 Programming Console (CVM1MP201-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.
1-9-4
Changes in Specifications for December 1995
The following specifications have been changed for CV500/CV1000/CV2000CPU01-V1 and CVM1-CPU01/CPU11/CPU21-V2 CPU Units with lot numbers for which the rightmost digit is 6 or later.
Easy Backup
Function Added
The user program, PC Setup, system settings for Special I/O Units, and IOM/
DM data can be backed up in Memory Cards or restored to the CPU Unit from
Memory Cards without using a Programming Device. (This is intended only as
a simplified backup method and we recommend you use a Programming
Device to confirm the results.)
Application Method
Backing Up from the CPU
Unit to a Memory Card
1,2,3...
The following conditions must be met.
1. A Memory Card must be inserted, it must be write-enabled, and there must
be sufficient space available on it to create the required files.
2. File memory instructions or Programming Devices must not be accessing
data on the Memory Card.
3. Pin 5 (automatic file transfer at power ON) on the basic setting DIP switch
must be OFF.
Restoring from a Memory
Card to the CPU Unit
1,2,3...
The following conditions must be met.
1. A Memory Card must be inserted and it must contain all of the specified
files.
2. The checksums and file sizes for all files must be correct.
3. The CPU Unit must be in PROGRAM mode.
4. Programming Devices must not be accessing data on the Memory Card.
5. Pin 5 (automatic file transfer at power ON) on the basic setting DIP switch
must be ON.
Specifying the Files to
Transfer and File Names
Pins 1 and 2 on the basic setting DIP switch are used to specify the files to be
transferred. These pins are normally used to specify the baud rate of the
peripheral device. Always return them to their original settings after completing the backup operation.

Section 1-9
Improved Specifications
Note If files of the same names already exist on the Memory Card, they will be
overwritten when data is backed up.
Starting and Indication of
Results
The backup or restore operation is started by pressing the Memory Card ON/
OFF switch for at least 3 seconds. If the CPU Units starts normally, the Memory Card indicator will flash until the file transfer has been completed and then
go out. (The time required for transfer depends on the amount of data being
transferred.) If there is not sufficient space when backing up files or if the
specified files do not exist when restoring data, the Memory Card indicator will
flash 5 times and then go out.
Note When transferring all data except for EM data for a CV1000 PC with a 1 MB
Memory Card, approximately 17 s will be required for backup and approximately 2 s will be required for restoring.
Using New Memory
Cards
The following commercially available memory cards can be used, but the
same application methods as the previous Memory Cards must be used.
JEIDA 4.0-compliant RAM cards,
64 KB, 128 KB, 256 KB, 512 KB, 1 MB, or 2 MB (See note.)
Note The CV500-MCW01 Memory Card Writer does not support 2 MB cards.

System Configuration
This section provides illustrations of CV-series PC Systems, which can be
classified 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 CVM1CPU21-EV2. The I/O capacity will be less depending on the Racks and the
types of Units mounted.
Systems with only
CV-series Expansion I/O
Racks
The following figure shows an assembled CV-series CPU Rack and seven
Expansion I/O Racks. Up to seven Expansion I/O Racks may be connected in
one or two series from the CPU Rack.
Series 1: Right connector on I/O Control Unit
Series 2: Left connector on I/O Control Unit
The total length of I/O Connecting Cable must be 50 m or less for each series
and a Termination Resistance Unit must be connected to the last Rack or to
the unused I/O Control Unit connector.
Note There are restrictions for some Units. Refer to Mounting Locations on page 26
for details.

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, Controller Link Units, BASIC Units, and Personal Computer Units) are required in a System, the CPU Rack may be
extended by connecting an Expansion 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 Expansion 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 connected 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.

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 Backplanes available for the CPU Rack. Any CPU can be mounted to any Backplane. The only differences 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
expansion 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
provide 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 as illustrated on
page 23. The CPU Backplane cannot be used for an Expansion CPU or
Expansion I/O Rack.

Expansion CPU Racks
An Expansion CPU Rack can be provided to increase the mounting space for
CPU Bus Units. The Expansion CPU Rack is connected directly to the CPU
Rack. Two cables are required to connect the Expansion CPU Rack to the
CPU Rack, a CPU Bus Cable and an I/O Connecting Cable. If either of these
connections is broken, the system will be disabled
Only one Expansion CPU Rack can be connected to the CPU Rack. To further
increase the number of I/O Units, a series of Expansion I/O Racks may be
connected to the Expansion CPU Rack or to the I/O Control Unit on the CPU
Rack. If no Expansion I/O Rack is connected to the I/O Interface Unit, connect
a Termination Resistance Unit to the unused connector on the I/O Interface
Unit.

Expansion I/O Racks
Expansion I/O Racks, shown in the following diagram, can be used to expand
the CV-series PCs. There are five models of Expansion I/O Backplane that
can be used, as shown in the following table. These vary in the number of
slots that they provide for Units (other than the Power Supply Unit and I/O
Interface Unit) and in expansion capabilities. CV500 Expansion I/O Backplanes offer complete expansion capabilities, while CVM1 Expansion I/O
Backplanes do not support I/O Interface Units and thus must be connected
directly to the CPU Backplane (see Single Expansion I/O Rack in this subsection).

An Expansion I/O Rack can be connected either directly to the CPU Backplane (see Single Expansion I/O Rack in this subsection) or to an I/O Control
Unit. Up to seven Expansion I/O Racks can be connected to the I/O Control
Unit on the CPU Rack in two series unless an Expansion CPU Rack is connected, in which case only six Expansion I/O Racks may be connected. If an
Expansion CPU Rack is connected, one of the series of Expansion I/O Racks
is connected to the I/O Control Unit on the CPU Rack and the other one is
connected to the I/O Interface Unit on the Expansion CPU Rack.
Attach a Termination Resistance Unit to the unused terminal on the I/O Interface Unit of the last Expansion I/O Rack in each series. If two series of Expansion I/O Racks are used, connect a Termination Resistance Unit to the last
Rack in each.

The SYSMAC BUS/2 Slave Racks use the same Expansion I/O Backplane
and Power Supply Unit as the Expansion I/O Racks, but a Remote I/O Slave
Unit is mounted instead of the I/O Interface Unit and the Slave Rack is connected from the Remote I/O Slave Unit to a Remote I/O Master Unit on the
CPU or Expansion CPU Rack. Refer to the SYSMAC BUS/2 Remote I/O System Manual for details.

Function
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.
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.

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 removed from the CPU without first being connected to a backup battery. EEPROM 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 instructions 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.

Four RAM Memory Card models are available, varying in memory capacity
from 8K, 16K, 32K to 64K words. Two 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 expectancies are given below.

altered or erased 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 [email protected]@ 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.

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
Expansion Data Memory Unit is optional. There are three models of Memory
Units available with different 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.

When mounted to the CPU, the Expansion Data Memory Unit is backed up by
the battery mounted in the CPU. Provided the Unit has been mounted to the
CPU for a duration of at least 1 minute, a charged capacitor built-in to the
Memory Unit allows the Unit to be removed from the CPU for up to 10 minutes
without memory loss.

Mounting Units
To build a Rack PC, we start with a Backplane. The 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
necessary for connecting the Units.
The first device we will mount to the Backplane is a Power Supply Unit. The
Power Supply Unit fits into the rightmost slot on the Backplane and provides
electricity 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
position directly to the left of the Power Supply Unit.
CPU
46
Section 3-1
Assembly
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 Appendix 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.
47
Section 3-1
Assembly
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 collective called an Expansion I/O Rack or an Expansion CPU Rack.
The differences 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.
CPU Rack
Expansion I/O Rack
I/O Interface Unit
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 Expansion 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, although 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.

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 mounting 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
Mounting a Memory Card
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.

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. Your body can carry an electrostatic 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 affect 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.
51
Section 3-3
Mounting Racks
Cooling
There are two points to consider in order to ensure that the PC does not overheat. The first is the clearance between the Racks, and the second is installation of a cooling fan.
Clearance between Racks
The Racks need to have sufficient room between each other to allow for I/O
wiring, 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 factors 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 specified. 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.
Fan
PC

3-3
Mounting Racks
Each Rack must be mounted vertically, that is, with the printing on the front
panels 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.
52
Section 3-3
Mounting Racks
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.

Power Supply Units
Use a commercially available 100 to 120-VAC or 200 to 240-VAC power
source to supply power to the AC Power Supply Unit; a 24-VDC power, for the
DC Power Supply Unit. Expansion I/O Racks and Expansion CPU Racks must
also be connected 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 Expansion 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 before 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.

2. The maximum switching capacity of the CV500-PS211 Power Supply Unit
is 2 A at 24 VDC when complying with EC Directives (low-voltage directives).
START Input
The START 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 MONITOR 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
emergency stop circuit in the next section.

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

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 interruption 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
resume 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
interruption time setting is not effective 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.

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.
Inductive Load Surge
Suppressor
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.

Input Leakage Current
When two-wire sensors, such as photoelectric sensors, proximity sensors or
limit switches with indicators are connected to the PC as input devices, the
input bit may be turned ON erroneously by leakage current. In order to prevent this, connect a bleeder resistor across the input to reduce the input
impedance.

Output Units
Output Short Protection
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
system. A fuse is recommended even if the Output Unit is provided with an
internal fuse (e.g., Transistor and Triac 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.

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.

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, damage may result. Check all I/O devices to make sure they meet
the specifications (refer to Appendix B Specifications). Be sure to allow for
leakage currents and load inductance.

Compliance with EC Directives
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 connected 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.
4. The maximum switching capacity of the CV500-PS211 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 standard (EN61000-6-4) of the EMC Directives as individual products. When
assembled 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 provided here as examples only.
Requirement
The following conditions can be used to determine if measures to reduce
noise are necessary. Refer to the EN61000-6-4 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.
72
Section 3-6
Compliance with EC Directives
Examples
Inductive Load Surge
Suppressor
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:
R:
0.5 to 1 µF for each amp of contact current
0.5 to 1 Ω 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 effect 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
C
R
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.
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 dielectric strength of the diode can be as low as 2 to 3 times the circuit
voltage.
Inductive load
Power supply
73
Section 3-7
Using the Noise-preventing Spacers
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
incandescent 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.

Using the Noise-preventing Spacers
When using a SYSMAC CVM1, CV500, CV1000, CV2000, or CVM1D PC
near a power device, a operating errors may result due to noise, so be sure to
use the Noise-preventing Spacers. By using Noise-preventing Spacers when
mounting a CPU Backplane, Expansion CPU Backplane, or Expansion I/O
Backplane, you can isolate the Unit from the control panel to prevent external
noise.
Noise-preventing Spacers are provided with CV-series Backplanes with the
production number 0180 or later (i.e., manufactured 01 August 2000 or later).
Reading the Production Number

Precautions for Use
• Make sure that the Spacers are mounted in the direction shown above.
Mounting in an incorrect direction may result in the device becoming
detached.
• When mounting a Backplane using Spacers, the vibration and shock
resistance given in the manual can no longer be assured. The mounting
height will also be raised by approximately 2 mm, so make sure that the
front panel of the Unit, the connector cables, etc., do not touch any other
device.
• In an environment where noise occurs, noise from the power supply cable
may also affect the device. Use a noise filter and isolation transformer or
similar device to screen the noise.

Wiring Dynamic Inputs
When a large number of bits must be controlled, an ID212 DC Input Unit can simplify wiring by inputting status
to up to 64 bits through only 16 points. Using digital switches or a specially wired keyboard, the different combinations of input points will determine which bits are ON. Two examples of connections using digital switches or
a keyboard are given.
123
Appendix B
Specifications
Connection Example 1 (Keyboard)
The wiring diagram and table below show how the ID212 DC Input Unit can be wired using a specially wired
keyboard. For example, if A on the keyboard is pressed, the combination of inputs on DATA 0 and STB 9 turn
ON bit 00 of word n. Similarly, the combination of inputs on DATA 7 and STB 7 turn ON bit 15 of word n+3. The
value of word n depends on where the Unit is mounted.

Note Because the DC Input Unit is operated on an extremely small current, make sure there is adequate distance between the DC Input Unit 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.
124
Appendix B
Specifications
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 different combinations of bits, the digital switches can control different 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 additional 32 bits.

Special Considerations for C500-OA225
The maximum current value allowed per output point depends on the ambient temperature and the number of
points per common that are ON simultaneously. The graph below shows the relationship between the allowable
current per point and the number of points ON per common. Be sure not to exceed the values shown in the
graph.

The graph below shows the value of the surge current and the time it takes the current to reach a steady state
(current-carrying time). The curved line in the graph represents the maximum value of surge current at which
the Unit can operate properly. It is suggested that when opening and closing a load with a large surge current,
to keep the value of the surge current to half the value shown the graph (within the shaded area).

Wiring Dynamic Outputs (3G2A5-OD211)
By using the OD211 DC Output Unit, a large number of outputs can be controlled through only 16 bits. Just like
the ID211 DC Input Unit, different combinations of bits can control different 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.

Note Because the DC Input Unit is operated on an extremely small current, make sure there is adequate distance between the DC Input Unit 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.
