!WARNING It is extremely important that a PLC and all PLC Units be used for the speci-

fied purpose and under the specified conditions, especially in applications that
can directly or indirectly affect human life. You must consult with your OMRON
representative before applying a PLC System to the above-mentioned appli­cations.

3 Safety Precautions

!WARNING The CPU Unit refreshes I/O even when the program is stopped (i.e., even in

PROGRAM mode). Confirm safety thoroughly in advance before changing the
status of any part of memory allocated to I/O Units, Special I/O Units, or CPU
Bus Units. Any changes to the data allocated to any Unit may result in unex­pected operation of the loads connected to the Unit. Any of the following oper­ation may result in changes to memory status.

• Transferring I/O memory data to the CPU Unit from a Programming
Device.

• Changing present values in memory from a Programming Device.

• Force-setting/-resetting bits from a Programming Device.

• Transferring I/O memory files from a Memory Card or EM file memory to
the CPU Unit.

• Transferring I/O memory from a host computer or from another PLC on a
network.

xxiv

!WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing

so may result in electric shock.

Safety Precautions 3

!WARNING Do not touch any of the terminals or terminal blocks while the power is being

supplied. Doing so may result in electric shock.

!WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do

so may result in malfunction, fire, or electric shock.

!WARNING Do not touch the Power Supply Unit while power is being supplied or immedi-

ately after power has been turned OFF. Doing so may result in electric shock.

!WARNING Provide safety measures in external circuits (i.e., not in the Programmable

Controller), including the following items, to ensure safety in the system if an
abnormality occurs due to malfunction of the PLC or another external factor
affecting the PLC operation. Not doing so may result in serious accidents.

With a CS1D System operating in Duplex Mode, operation will be stopped
and all outputs will be turned OFF in the following circumstances.

• When self-diagnosis simultaneously detects an error in both the active
and standby CPU Units.

• When a severe failure alarm (FALS) instruction is simultaneously exe­cuted in both the active and standby CPU Units.

• When self-diagnosis detects an error in Simplex Mode or when it detects
an error during duplex initialization for Duplex Mode.

• When a severe failure alarm (FALS) instruction is executed in Simplex
Mode or during duplex initialization for Duplex Mode.

Unexpected operation, however, may still occur for errors in the I/O control
section, errors in I/O memory, and other errors that cannot be detected by the
self-diagnosis function. As a countermeasure for all such errors, external
safety measures must be provided to ensure safety in the system.

!WARNING The PLC outputs may remain ON or OFF due to deposition or burning of the

output relays or destruction of the output transistors. As a countermeasure for
such problems, external safety measures must be provided to ensure safety in
the system.

!WARNING When the 24-V DC output (service power supply to the PLC) is overloaded or

short-circuited, the voltage may drop and result in the outputs being turned
OFF. As a countermeasure for such problems, external safety measures must
be provided to ensure safety in the system.

!Caution Confirm safety before transferring data files stored in the file memory (Mem-

ory Card or EM file memory) to the I/O area (CIO) of the CPU Unit using a
peripheral tool. Otherwise, the devices connected to the output unit may mal­function regardless of the operation mode of the CPU Unit.

!Caution Fail-safe measures must be taken by the customer to ensure safety in the

event of incorrect, missing, or abnormal signals caused by broken signal lines,
momentary power interruptions, or other causes. Serious accidents may
result from abnormal operation if proper measures are not provided.

Operating Environment Precautions 4

!Caution Execute online edit only after confirming that no adverse effects will be

caused by extending the cycle time. Otherwise, the input signals may not be
readable.

!Caution The CS1D CPU Units automatically back up the user program and parameter

data to flash memory when these are written to the CPU Unit. I/O memory
(including the DM, EM, and HR Areas), however, is not written to flash mem­ory. The DM, EM, and HR Areas can be held during power interruptions with a
battery. If there is a battery error, the contents of these areas may not be
accurate after a power interruption. If the contents of the DM, EM, and HR
Areas are used to control external outputs, prevent inappropriate outputs from
being made whenever the Battery Error Flag (A40204) is ON.

!Caution Confirm safety at the destination node before transferring a program to

another node or changing contents of the I/O memory area. Doing either of
these without confirming safety may result in injury.

!Caution Tighten the screws on the terminal block of the AC Power Supply Unit to the

torque specified in the operation manual. The loose screws may result in
burning or malfunction.

!Caution Caution is required when connecting peripheral devices, such as a personal

computer, to the PLC when Units with non-isolated power supplies, such as
the CS1W-CLK12/CLK52(-V1), that are connected to an external power sup­ply are mounted to the PLC. If the 24-V side is grounded on the external
power supply, a short will be created if the 0-V side of the peripheral device is
grounded. When connecting peripheral devices, either ground the 0-V side of
the external power supply or do not ground the external power supply at all.

4 Operating Environment Precautions

!Caution Do not operate the control system in the following locations:

• Locations subject to direct sunlight.

• Locations subject to temperatures or humidity outside the range specified
in the specifications.

• Locations subject to condensation as the result of severe changes in tem­perature.

• Locations subject to corrosive or flammable gases.

• Locations subject to dust (especially iron dust) or salts.

• Locations subject to exposure to water, oil, or chemicals.

• Locations subject to shock or vibration.

xxvi

!Caution Take appropriate and sufficient countermeasures when installing systems in

the following locations:

• Locations subject to static electricity or other forms of noise.

• Locations subject to strong electromagnetic fields.

• Locations subject to possible exposure to radioactivity.

• Locations close to power supplies.

Application Precautions 5

!Caution The operating environment of the PLC System can have a large effect on the

longevity and reliability of the system. Improper operating environments can
lead to malfunction, failure, and other unforeseeable problems with the PLC
System. Be sure that the operating environment is within the specified condi­tions at installation and remains within the specified conditions during the life
of the system.

5 Application Precautions

Observe the following precautions when using the PLC System.

• Do not use the C200H/CS-series Power Supply Units (C200H-P@@@@)
in a CS1D PLC. System operation will not be dependable and may stop.

• Do not use a CS1D Power Supply Unit (CS1D-PA/PD@@@) for any PLC
other than a CS1D PLC. Operational errors and burning will result.

• If duplex Power Supply Units are to be used, calculate the current con­sumption so that the system will be able to operate with a single Power
Supply Unit in case an error occurs in the other Power Supply Unit. If two
different kinds of Power Supply Units are to be used, calculate the current
consumption using the output of the smaller-capacity Power Supply Unit.

• In a CS1D Duplex CPU System, always mount the CS1D-CPU@@H/P
CPU Units for Duplex CPU Systems to the CS1D-BC052/BC042D CPU
Backplane. Faulty operation will occur if any other CPU Unit is mounted.

• In a CS1D Single CPU System, always mount a CS1D-CPU@@S CPU
Unit for Single CPU Systems to the CS1D-BC82S CPU Backplane. Faulty
operation will occur if any other CPU Unit is mounted.

• Do not mount a CS1D-CPU@@H/P/S CPU Unit to a CS1W-BC@@ (non­CS1D) CPU Backplane. Otherwise, faulty operation will occur.

• The cycle time will be increased over the normal cycle time whenever
duplex operation is initialized, including when power is turned ON, when
the initialization button is pressed, when operation is started, and when
data is transferred. The increase will be a maximum of 190 ms for the
CS1D-CPU65H and 520 ms for the CS1D-CPU67H. Set the monitoring
time (10 to 40,000 ms, default: 1 s) for the cycle time high enough to allow
for this increase. Also, confirm that the system will operate correctly and
safely even for the maximum cycle time, including the increase for duplex
initialization.

• If operation switches from Duplex Mode to Simplex Mode, processing to
synchronize the active and standby CPU Units will no longer be per­formed, resulting in a shorter cycle time. The more instructions requiring
synchronization (such as IORF, DLNK, IORD, IOWR, PID, RXD, FREAD,
and FWRIT) are used, the greater the difference between Duplex Mode
and Simplex Mode operation will be (with Duplex Mode having the longer
cycle time). Confirm that the system will operate correctly and safely even
for the cycle time in both Simplex and Duplex Modes.

• If the active CPU Unit is switched when PTs or host computers are con­nected to the RS-232C port on both the active and standby CPU Units,
communications may be interrupted momentarily. Always enable retry
process in communications programs at the PTs or host computers.

• Before replacing a Unit online, always disable the operation of all con­nected external devices before starting the replacement procedure. Unex­pected outputs from the Unit being replaced may result in unexpected
operation of controlled devices or systems.

Application Precautions 5

• Always following the procedures provided in the operation manual when
performing online replacement.

• When replacing a Unit online, always replace it with a Unit that has the
same specifications.

• When replacing a Duplex Unit online in a Duplex CPU, Dual I/O Expan­sion System, always follow the procedure provided in this operation man­ual.

• When replacing a Connecting Cable or Expansion Unit online in a Duplex
CPU, Dual I/O Expansion System, always follow the procedure provided
in this operation manual.

• When using duplex Connecting Cables in a Duplex CPU, Dual I/O Expan­sion System, always use cables that are the same length.

• In a Duplex CPU, Dual I/O Expansion System, do not connect two Con­necting Cables to Expansion Backplanes that are in different operating
levels. Doing so may cause improper operation.

• Before removing a Unit during operation without a PLC Programming
Device (CX-Programmer or a Programming Console), always confirm that
the Removal of a Unit without a Programming Device or Removal/Addition
of Units without a Programming Device function is enabled in the PLC
Setup. If a Unit is removed while the PLC Setup is not set to enable Unit
removal without a Programming Device, an I/O bus error will occur and
the PLC (CPU Unit) will stop operating.

• When a Unit has been removed during operation without a PLC Program­ming Device (CX-Programmer or a Programming Console), data trans­ferred from the removed Unit to the CPU Unit may be invalid. If an invalid
data transfer will adversely affect the system, use a Programming Device
to replace the Unit online.

• When the Removal of a Unit without a Programming Device or Removal/
Addition of Units without a Programming Device function is enabled in the
PLC Setup and a Special I/O Unit has been removed, the Special I/O Unit
Area words allocated to that Unit for data transfer (to and from the CPU
Unit) will be cleared. If the loss of the Special I/O Unit Area data will
adversely affect the system, disable these functions in the PLC Setup and
use a Programming Device to replace the Unit online. (When a Program­ming Device is used to replace the Unit online, the data in the Special I/O
Unit Area is retained while the Unit is removed.)

• An I/O bus error, which can be caused by a Unit malfunction, is normally a
fatal error that stops operation. When he Removal of a Unit without a Pro­gramming Device or Removal/Addition of Units without a Programming
Device function is enabled in the PLC Setup, the I/O bus error will be
treated as a non-fatal error and PLC (CPU Unit) will not stop operating. If
there are any Units that will adversely affect the system if an I/O bus error
occurs, do not enable these functions in the PLC Setup.

• Do not turn ON the Maintenance Start Bit (A80015) continuously from the
ladder program. As long as the Maintenance Start Bit is ON, errors will
not be generated even if there are Unit malfunctions, so the system may
be adversely affected.

Note The Maintenance Start Bit is provided to prevent non-fatal errors

from occurring during Unit removal without a Programming Device.

• Do not turn ON the Online Replacement Completed Bit (A80215) continu­ously from the ladder program. If the Unit is mounted while the Online
Replacement Completed Bit is ON, the PLC (CPU Unit) may stop operat­ing.

xxviii

Application Precautions 5

Note The Online Replacement Completed Bit is provided to restart the

data exchange between the replaced Unit and CPU Unit. After a
Unit has been replaced without a Programming Device, turn ON the
Online Replacement Completed Bit to restart the data exchange.

• Always turn OFF the reserved pin (RSV) of the Duplex Unit's Communica­tions Setting DIP Switch.

• Never connect pin 6 (5-V power supply) on the RS-232C port on the CPU
Unit to any device other than an NT-AL001, CJ1W-CIF11 Adapter, or
NV3W-M@20L Programmable Terminal. The external device or the CPU
Unit may be damaged.

• You must use the CX-Programmer (programming software that runs on
Windows) if you need to program more than one task. A Programming
Console can be used to program only one cyclic task. A Programming
Console can, however, be used to edit multitask programs originally cre­ated with the CX-Programmer.

!WARNING Always heed these precautions. Failure to abide by the following precautions

could lead to serious or possibly fatal injury.

• Always connect to a ground of 100 Ω or less when installing the Units. Not
connecting to a ground of 100 Ω or less may result in electric shock.

• A ground of 100 Ω or less must be installed when shorting the GR and LG
terminals on the Power Supply Unit.

• Always turn OFF the power supply to the PLC before attempting any of
the following. Not turning OFF the power supply may result in malfunction
or electric shock.

• Mounting or dismounting Power Supply Units, I/O Units, CPU Units, In­ner Boards, or any other Units.

• Assembling the Units.

• Setting DIP switches or rotary switches.

• Connecting cables or wiring the system.

• Connecting or disconnecting the connectors.

!Caution Failure to abide by the following precautions could lead to faulty operation of

the PLC or the system, or could damage the PLC or PLC Units. Always heed
these precautions.

• The user program and parameter area data in the CPU Units are backed
up in the built-in flash memory. The BKUP indicator will light on the front
of the CPU Unit when the backup operation is in progress. Do not turn
OFF the power supply to the CPU Unit when the BKUP indicator is lit. The
data will not be backed up if power is turned OFF.

• The PLC Setup is set to specify using the mode set on the Programming
Console and a Programming Console is not connected, the CPU Unit will
start in RUN mode. This is the default setting in the PLC Setup. (A CS1
CPU Unit will start in PROGRAM mode under the same conditions.)

• When creating an AUTOEXEC.IOM file from a Programming Device (a
Programming Console or the CX-Programmer) to automatically transfer
data at startup, set the first write address to D20000 and be sure that the
size of data written does not exceed the size of the DM Area. When the
data file is read from the Memory Card at startup, data will be written in

xxix

Application Precautions 5

the CPU Unit starting at D20000 even if another address was set when
the AUTOEXEC.IOM file was created. Also, if the DM Area is exceeded
(which is possible when the CX-Programmer is used), the remaining data
will be written to the EM Area. Refer to information on file operations in
the CS/CJ Series Programming Manual for details.

• Always turn ON power to the PLC before turning ON power to the control
system. If the PLC power supply is turned ON after the control power sup­ply, temporary errors may result in control system signals because the
output terminals on DC Output Units and other Units will momentarily turn
ON when power is turned ON to the PLC.

• Fail-safe measures must be taken by the customer to ensure safety in the
event that outputs from Output Units remain ON as a result of internal cir­cuit failures, which can occur in relays, transistors, and other elements.

• Fail-safe measures must be taken by the customer to ensure safety in the
event of incorrect, missing, or abnormal signals caused by broken signal
lines, momentary power interruptions, or other causes.

• Interlock circuits, limit circuits, and similar safety measures in external cir­cuits (i.e., not in the Programmable Controller) must be provided by the
customer.

• Do not turn OFF the power supply to the PLC when data is being trans­ferred. In particular, do not turn OFF the power supply when reading or
writing a Memory Card. Also, do not remove the Memory Card when the
BUSY indicator is lit. To remove a Memory Card, first press the memory
card power supply switch and then wait for the BUSY indicator to go out
before removing the Memory Card.

• If the I/O Hold Bit is turned ON, the outputs from the PLC will not be
turned OFF and will maintain their previous status when the PLC is
switched from RUN or MONITOR mode to PROGRAM mode. Make sure
that the external loads will not produce dangerous conditions when this
occurs. (When operation stops for a fatal error, including those produced
with the FALS(007) instruction, all outputs from Output Unit will be turned
OFF and only the internal output status will be maintained.)

• The contents of the DM, EM, and HR Areas in the CPU Unit are backed
up by a Battery. If the Battery voltage drops, this data may be lost. Provide
countermeasures in the program using the Battery Error Flag (A40204) to
re-initialize data or take other actions if the Battery voltage drops.

• When supplying power at 200 to 240 V AC, always remove the metal
jumper from the voltage selector terminals on the Power Supply Unit
(except for Power Supply Units with wide-range specifications). The prod­uct will be destroyed and must be replaced if 200 to 240 V AC is supplied
while the metal jumper is attached. Refer to 5-4 Wiring Methods for
details.

• Always use the power supply voltages 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-cir­cuiting in external wiring. Insufficient safety measures against short-cir­cuiting may result in burning.

• Install the Units as far away as possible from devices that generate
strong, high-frequency noise.

xxx

Application Precautions 5

• 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 voltage 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 Units properly as specified in the operation manuals. Improper
installation of the Units may result in malfunction.

• Be sure that all the Backplane mounting screws, terminal block screws,
and cable connector screws are tightened to the torque specified in the
relevant manuals. Incorrect tightening torque may result in malfunction.

• Leave the label attached to the Unit when wiring. Removing the label may
result in malfunction if foreign matter enters the Unit.

• Remove the label after the completion of wiring to ensure proper heat dis­sipation. Leaving the label attached 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.

• Wire all connections correctly.

• Double-check all wiring and switch settings before turning ON the power
supply. Incorrect wiring may result in burning.

• Mount Units only after checking terminal blocks and connectors com­pletely.

• 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 switch settings, the contents of the DM Area, and other prepara­tions before starting operation. Starting operation without the proper set­tings or data may result in an unexpected operation.

• Check the user program for proper execution before actually running it on
the Unit. Not checking the program may result in unexpected operation.

• Confirm that no adverse effect 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 PLC (including the setting of the
startup operating mode).

• 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 or other wiring lines. Doing so
may break the cables.

• Do not use commercially available RS-232C personal computer cables.
Always use the special cables listed in this manual or make cables
according to manual specifications. Using commercially available cables
may damage the external devices or CPU Unit.

xxxi

Application Precautions 5

• When replacing parts, be sure to confirm that the rating of a new part is
correct. Not doing so may result in malfunction or burning.

• Before touching a Unit, be sure to first touch a grounded metallic object in
order to discharge any static build-up. Not doing so may result in malfunc­tion or damage.

• When transporting or storing circuit boards, cover them in antistatic mate­rial to protect them from static electricity and maintain the proper storage
temperature.

• Do not touch circuit boards or the components mounted to them with your
bare hands. There are sharp leads and other parts on the boards that
may cause injury if handled improperly.

• Do not short the battery terminals or charge, disassemble, heat, or incin­erate the battery. Do not subject the battery to strong shocks. Doing any
of these may result in leakage, rupture, heat generation, or ignition of the
battery. Dispose of any battery that has been dropped on the floor or oth­erwise subjected to excessive shock. Batteries that have been subjected
to shock may leak if they are used.

• UL standards required that batteries be replaced only by experienced
technicians. Do not allow unqualified persons to replace batteries.

• Dispose of the product and batteries according to local ordi­nances as they apply. Have qualified specialists properly
dispose of used batteries as industrial waste.

• Separate the line ground terminal (LG) from the functional ground termi­nal (GR) on the Power Supply Unit before performing withstand voltage
tests or insulation resistance tests.

• Do not drop the product or subject it to excessive vibration or shock.

6-2 Concepts

EMC Directives

OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or the
overall machine. The actual products have been checked for conformity to
EMC standards (see the following note). Whether the products conform to the
standards in the system used by the customer, however, must be checked by
the customer.

EMC-related performance of the OMRON devices that comply with EC Direc­tives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel on which the OMRON devices are installed.
The customer must, therefore, perform the final check to confirm that devices
and the overall machine conform to EMC standards.

Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:

EMS (Electromagnetic Susceptibility): EN61131-2 or EN61000-6-2
EMI (Electromagnetic Interference): EN61000-6-4

Low Voltage Directive

Always ensure that devices operating at voltages of 50 to 1,000 V AC and 75
to 1,500 V DC meet the required safety standards for the PLC (EN61131-2).

6-3 Conformance to EC Directives

The CS1D Duplex PLCs comply with EC Directives. To ensure that the
machine or device in which the CS1D Duplex PLC is used complies with EC
Directives, the PLC must be installed as follows:

1,2,3... 1. The CS1D Duplex PLC must be installed within a control panel.

2. You must use reinforced insulation or double insulation for the DC power
supplies used for the communications power supply and I/O power sup­plies.

3. CS1D Duplex PLCs complying with EC Directives also conform to the
Common Emission Standard (EN61000-6-4). Radiated emission charac­teristics (10-m regulations) may vary depending on the configuration of the
control panel used, other devices connected to the control panel, wiring,
and other conditions. You must therefore confirm that the overall machine
or equipment complies with EC Directives.

(Radiated emission: 10-m regulations)

Conformance to EC Directives 6

6-4 Relay Output Noise Reduction Methods

The CS1D Duplex PLCs conforms to the Common Emission Standards
(EN61000-6-4) of the EMC Directives. However, noise generated by relay out­put switching may not satisfy these Standards. In such a case, a noise filter
must be connected to the load side or other appropriate countermeasures
must be provided external to the PLC.

Countermeasures taken to satisfy the standards vary depending on the
devices on the load side, wiring, configuration of machines, etc. Following are
examples of countermeasures for reducing the generated noise.

Countermeasures

(Refer to EN61000-6-4 for more details.)
Countermeasures are not required if the frequency of load switching for the

whole system with the PLC included is less than 5 times per minute.
Countermeasures are required if the frequency of load switching for the whole

system with the PLC included is more than 5 times per minute.

Countermeasure Examples

When switching an inductive load, connect an surge protector, diodes, etc., in
parallel with the load or contact as shown below.

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 experi­ments, 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

1-1-1 CS1D Duplex System Overview

The CS1D Duplex System is a highly reliable Programmable Controller (PLC)
System. By providing duplex CPU Units, Power Supply Units, and Communi­cations Units, the CS1D can continue control operations and be restored with
no need to shut down the entire system in the event of an error or malfunction.

Select from either of two Duplex Systems: A Duplex CPU System or a Single
CPU System. A Duplex CPU System includes two CPU Units. Even if an error
occurs in the active CPU Unit, the standby CPU Unit continues operation,
thus preventing a system shutdown. The Single CPU System uses a single
CPU Unit. In either System, duplex Power Supply Units or Communications
Units can be used to provide high reliability in the event of an error in the
power supply system or the active Communications Unit.

It is now possible to select a Duplex CPU with duplex Connecting Cables
(Dual I/O Expansion System), as well as the previously available Duplex CPU
with a single Connecting Cable (Single I/O Expansion System).

1-1-2 CS1D Duplex System Features

Duplex CPU Systems

Two CPU Units and one Duplex Unit are mounted.
The two CPU Units always run the same user's program. One of them exe-

cutes the system I/O while the other remains on standby. If an error (see note)
occurs in the controlling CPU Unit (called the active CPU Unit), control is
switched to the other CPU Unit (called the standby CPU Unit), and operation
continues. (The system will stop, however, if the same error occurs in the
standby CPU Unit, or if another operation switching error or a fatal error
occurs.)

Note Operation will be taken over by the standby CPU Unit for any of the following

operation switching errors: CPU error, memory error, cycle time overrun error,
program error, FALS error, or fatal Inner Board error. (A fatal Inner Board error
applies only to Process-control CPU Units.)

Using the Hot Standby Method

With the hot standby method, the standby CPU Unit operates with the same
status as the active CPU Unit. Using this method provides the following bene­fits.

3

CS1D Duplex System Overview and Features Section 1-1

1,2,3... 1. There is no need to incorporate special programming for duplex opera-

tions, such as programming to switch when an error occurs, and thus there
is no need for the duplex setup to be considered in individual parameter
settings.

2. The time required for switching when an error occurs is shortened, en­abling operation to be continued without any interruption.

Standby CPU Unit:
Remains on standby while
executing the program.

Automatic Recovery to Duplex Mode

With existing Duplex CPU Systems (such as the CVM1D), it is necessary to
manually return the system to Duplex Mode after a CPU Unit error occurs dur­ing operation in Duplex Mode and operation is switched to Simplex Mode.

With the CS1D Duplex System, operation is automatically returned to the orig­inal Duplex Mode when the error that caused the switch to Simplex Mode is
cleared.

Unmanned duplex operation can be continued even when incidental errors
occur temporarily due to causes such as noise.

No special programming
is required, because
duplex CPU Units are
operating.

Single CPU Systems

Although only a single CPU Unit is mounted, duplex Power Supply Units,
duplex Communications Units, and online Unit replacement are possible.

Duplex Power Supply Units

Power is always supplied in parallel from two Power Supply Units. Even if one
of the Power Supply Units breaks down, the other one continues providing
power automatically. Power Supply Unit models for AC power and DC power
are both available, and a combination of both types can be used. A Power
Supply Unit that malfunctions or for which a broken line occurs can be con­firmed by means of flags in the AR Area. If a Power Supply Unit malfunctions,
it can be replaced online without turning OFF the power supply or stopping
operation.

Duplex Communications Units

Duplex Controller Link
Units Using Active/
Standby Units

Two Communications Units (see note) are connected by fiber-optic cable. If
one of the Units stops communicating, the other one continues communica­tions.

Note The following Communications Units support duplex operation: The CS1W-

CLK12-V1 (H-PCF Cable) and the CS1W-CLK52-V1 (GI Cable) Controller
Link Units.

As shown in the following diagram, two Controller Link Units are mounted in a
single network with identical unit numbers and node addresses. One of the
Controller Link Units is in standby mode.

When an error is detected at the active Controller Link Unit, the standby Con­troller Link Unit switches to active operating status. This allows communica­tions to continue without the node being disconnected.

Using duplex Ethernet Units and redundant communications lines increases
the reliability of the network. The communications lines use a primary line and
a secondary line, to which Ethernet Units are connected. Normally the pri­mary communications line is used, but operation will switch to the secondary
communications line automatically if an error occurs in the primary communi­cations line or the primary Ethernet Unit, thereby allowing continuous commu­nications.

• Duplex Ethernet Units do not require duplex programming considerations.
The CPU Unit select the Unit to use as the send destination.

• Ethernet Units use 100Base-TX and support high-speed communica­tions.

CPU Unit Ver. 1.1 or later and CX-Programmer Ver. 4.0 or higher. Duplex
operation of Ethernet Units for a Single CPU System is possible for any CS1D
CPU Unit for Single CPU Systems, but CX-Programmer Ver. 4.0 or higher is
required.

Duplex CPU, Dual I/O Expansion System (Duplex CPU System Only)

A more reliable system can be configured by expanding the Duplex CPU Sys­tem.

CS1D Duplex System Overview and Features Section 1-1

Note A Duplex CPU, Dual I/O Expansion System requires compatible Duplex Units,

CPU Backplane, Expansion Backplanes, I/O Control Units, I/O Interface Units,
and Duplex CPU Units with unit version 1.3 or later.

Duplex Connecting Cables When the Connecting Cable between the CPU Rack and Expansion Racks is

duplexed, the system can continue operating through the second Cable if one
Cable is damaged or disconnected.

Online Replacement of
Duplex Units

Replacement of Basic and
Special I/O Units without a
Programming Device

Online Addition of Units
and Expansion
Backplanes

If a Duplex Unit fails, the faulty Unit can now be replaced online. (The PLC
operates in simplex mode while the Duplex Unit is being replaced.)

If the Removal/Addition of Units without a Programming Device function is
enabled in advance, Units can be removed and mounted without any CX-Pro­grammer or Programming Console operations.

A CX-Programmer operation can be used to add a Basic I/O Unit, Special I/O
Unit, or Expansion Backplane to an existing Rack. An operating Rack can be
expanded without stopping the Rack.

CS Series Compatibility

The CS1D CPU Units (CS1D-CPU@@H and CS1D-CPU@@S) are based on
the architecture of CS1-H CPU Units and can use the same programs and
Units as the CS1 and CS1-H CPU Units.

For a comparison of functions between the CS1D and CS1-H Units, refer to
Appendix E Precautions in Replacing CS1-H PLCs with CS1D PLCs.

Online Replacement of CPU Units

CPU Units can be replaced online without stopping system operation.

Online Replacement of Basic I/O Units, Special I/O Units, and CPU Bus Units

Basic I/O Units, Special I/O Units, and CPU Bus Units can be replaced online
by using Programming Console or CX-Programmer operations (see note). In
particular, with Duplex Communications Units (e.g., Ethernet Units and Con­troller Link Units, optical ring type, token ring mode). Communications Units
can be replaced without disconnecting the node or interrupting communica­tions.

Note 1. Online Unit replacement is possible with CX-Programmer Ver. 3.1 or high-

er.

2. When CS1D CPU Units with unit version 1.3 or later are being used and
the Removal/Addition of Units without a Programming Device function has
been enabled in advance, Units can be replaced without any CX-Program­mer or Programming Console operations.

System Configuration Section 1-2

The Two Modes in a CS1D Duplex CPU System

A CS1D Duplex CPU System can be operated in either Duplex Mode or Sim­plex Mode.

• Duplex Mode
In Duplex Mode, the CPU Units are placed in duplex system status. If a
fatal error occurs in the active CPU Unit, control is switched to the standby
CPU Unit and operation continues.

• Simplex Mode
In Simplex Mode, a single CPU Unit controls operation.

lowing two modes:
Duplex Mode (DPL)

The system operates with CS1D CPU Units and CS1D
Power Supply Units in duplex status.

Simplex Mode (SPL)
The system operates with just a single CS1D CPU Unit.

Hot standby method: One of the two CS1D CPU Units
actually controls operations, and the other is on standby
as a backup. The two CS1D CPU Units have the same I/O
memory, and parameters (PLC Setup, I/O tables, etc.),
and both run the same user’s program.

Their operation differ in the following points:
The active CPU Unit executes I/O refreshing and all event

servicing.
The standby CPU Unit handles file accessing (read only)

and FINS command execution event servicing (read only).
Power interruptions

(CPU operation set­ting switch: NO
USE), CPU errors,
memory errors, pro­gram errors, cycle
time overrun errors,
FALS executions,

errors

After operation has been switched from Duplex Mode to
Simplex Mode as a result of any of the operation switching
errors listed above, operation is automatically returned to
Duplex Mode when it is determined that the cause of the
error has been cleared. Automatic recovery to duplex
operation must first be enabled in the PLC Setup. (The
recovery can be repeated up to ten times.)

Identical models must be used for the two CS1D CPU
Units.

The same user program areas must be used.
The same parameter areas (PLC Setup, etc.) must be

used.
The same Inner Board data must be used (Process-con-

trol CPU Units only).
Only the functions that can be executed by both CPU

Units can be used (when the unit versions of the CPU
Units are not the same).

The CS1D CPU Unit where the error occurred can be
replaced online by turning OFF the power to only that Unit
(i.e., setting the CPU operation switch to NO USE).

If any of the errors listed on the left
occur in the active CPU Unit, stop­ping operation, the standby CPU
Unit automatically switches to active
status and takes over control. At the
same time, the mode is switched to
Simplex Mode. The CPU Unit where
the error occurred can be replaced
without stopping system operation.

Note A fatal Inner Board error

applies only to Process-con­trol CPU Units.

If either of the errors listed on the
left occurs in Duplex Mode, the
active CPU Unit remains the same
and operation is switched to Sim­plex Mode.

When two Optical-ring Controller Link Units for duplex communications (H-PCF
cable: CS1W-CLK12-V1; GI cable: CS1W-CLK52-V1) are mounted using the
same node address and unit number, and a special cable is used to connect
them, one of the Units will continue communications even if the other one breaks
down (active-standby Units)

Duplex Ethernet Units
Two CS1D-ETN21D Ethernet Units are mounted. One is connected to the sec-

ondary communications line and the other to the primary communications line,
thereby increasing reliability of the network (primary/secondary communications
lines).

Two Connecting Cables are installed between the CPU Rack and Expansion
Racks. If one Connecting Cable is removed or damaged, operation continues
using the other cable.

Using the Programming Console, it is possible to mount or remove CS-series
Basic I/O Units, CS-series Special I/O Units, and CS-series CPU Bus Units while
the power is ON and the CPU Unit is operating in any mode (PROGRAM, MON­ITOR, or RUN).

When Unit removal without a Programming Device is enabled in the PLC Setup,
a Unit can be removed without using the CX-Programmer or a Programming
Console.

Note Unit removal without Programming Device is possible only in a CS1D

Duplex System (Unit Ver. 1.2 or later). After the replacement Unit is
mounted, the Online Replacement Completed Bit must be turned ON.

If the Removal/Addition of Units without a Programming Device function is
enabled in advance, Units can be removed and mounted without CX-Program­mer or Programming Console operations.

Note This function is possible only in a Duplex CPU, Dual I/O Expansion Sys-

tem.

If there is a Duplex Unit error, the Duplex Unit can be replaced during operation.
The Duplex Unit in which the error occurred can be replaced after turning OFF
power to the Unit by setting the DPL USE/NO USE Switch to NO USE.

Note This function is possible only in a Duplex CPU, Dual I/O Expansion Sys-

tem. The PLC operates in simplex mode while the Duplex Unit is being
replaced.

A new Basic I/O Unit, Special I/O Unit, or Expansion Backplane can be added
during operation. to an existing Rack. An operating Rack can be expanded with­out stopping the Rack.

Note This function is possible only in a Duplex CPU, Dual I/O Expansion Sys-

tem or Duplex CPU, Single I/O Expansion System with CPU Units that
have unit version 1.2 or later. Backplanes can be replaced only in a
Duplex CPU, Dual I/O Expansion System.

Secure cables help prevent Expansion Rack Cables from being disconnected
accidentally.

Power is supplied to the Backplane simultaneously by two
CS1D Power Supply Units. (The load for each CS1D
Power Supply Unit is approximately one half.)

If one CS1D Power Supply Unit breaks down (i.e., if the
power supply voltage drops), operation is continued using
only the other one.

When a constant monitoring system, such as a PT or personal computer appli­cation, is connected to the CPU Unit’s RS-232C port, an RS-232C/RS-422
Adapter can be used to connect to both the active and standby CS1D CPU
Units.

Set the standby CPU Unit’s RS-232C port setting in the PLC Setup so that it
cannot be used independently.

When writing to a Memory Card, the same data is written to not only the Memory
Card mounted in the active CPU Unit, but also to the one mounted in the
standby CPU Unit.

Note In the PLC Setup, duplex operation must be enabled for Memory Cards.
Note No processing is executed during duplex initialization to match the data

on the Memory Cards mounted in the active and standby CPU Units even
if the data is not the same. Therefore, before enabling duplex operation
for Memory Cards, make sure that the contents are the same for both of
the Memory Cards.

Note When EM File Memory is set for duplex operation, processing is exe-

cuted to match the contents of EM File Memory in both CPU Units. It is
not necessary to enable duplex operation for Memory Cards in the PLC
Setup.

CX-Programmer Ver. 3.@ or lower: The Duplex CPU Sys­tem uses the CS1D-CPU@@H, so select “CS1H-H” as the
device type. This version does not support Single CPU
Systems.

CX-Programmer Ver. 4.0 or higher: The Duplex CPU Sys­tem uses the CS1D-CPU@@H, so select “CS1D-H” or
“CS1H-H” as the device type. The Single CPU System
uses the CS1D-CPU
device type.

Cable connection: Connect to the peripheral port or RS­232C port of the active CPU Unit.

Note If a CX-Programmer is connected to the standby

CPU Unit in a Duplex CPU System, write process­ing from the CX-Programmer cannot be executed.

The timer PV is not refreshed when the timer instruction is jumped for JMP,

CJMP, or CJPN-JME. The PV will be refreshed for the entire period it was
jumped the next time it is executed (i.e., the next time it is not jumped). (With
CS1-H CPU Units, the PV for these timers were refreshed even when jumped.)

TIMW(813), TIMWX(816), TMHW(815), TMHWX(817):
When the input condition for BPRG is OFF, or when the block program is tempo-

rarily stopped by BPPS, the timer PV is not refreshed. (With the CS1-H CPU

Note 1. The above inrush current value is for a cold start at normal temperatures.

The inrush current circuit for this power supply includes a thermistor ele­ment (for current suppression at low temperatures). If the ambient temper­ature is too high, the thermistor element will not be cool enough, so the
above inrush current value may be exceeded (by as much as double the
value shown). Provide a sufficient margin by taking this into consideration
along with breaking or detection characteristics when selecting fuses and
breakers for external circuits.

2. Disconnect the CS1D Power Supply Unit’s LG terminal from the GR termi­nal when testing insulation and dielectric strength. Testing the insulation
and dielectric strength with the LG terminal and the GR terminals connect­ed will damage internal circuits in the CPU Unit.

3. Supported when mounted to a Backplane.

2-2-2 Expansion Racks

It is possible to connect Expansion Racks in order to mount Units outside of
the CS1D CPU Rack.

There are two types of Expansion Racks that can be connected: CS1D
Expansion Racks and CS1D Long-distance Expansion Racks. Both Racks
can be connected to Duplex CPU Systems and Simple-CPU Systems, but the
appropriate CS1D Backplane must be used for either type of Rack.

Note Neither CS-series Expansion Racks nor C200H Expansion I/O Racks can be

connected to a CS1D CPU Rack.

!Caution Always touch a grounded metal object to discharge static electricity from your

body before changing the settings on the DIP switch during operation.

Note 1. When pin 1 is set to ON, writing is prohibited for the user program and all

parameter data (PLC Setup, I/O table registration, etc.). Moreover, it is not
possible to clear the user program or parameters even by executing a
memory clear operation from a Programming Device.

2. In a Duplex CPU System, automatic transfer at startup can be executed
only from the active CPU Unit. Duplex initialization is performed between
the two CPU Units after the automatic transfer, and the user program, pa­rameters, and I/O memory are matched. If pin 2 it set to ON, I/O memory
(AUTOEXEC.IOM, ATEXEC@@.IOM) will also be transferred automatical­ly. (Refer to the Programming Manual.) The program (AUTOEXEC.OBJ)
and Parameter Area (AUTOEXEC.STD) must both be on the Memory
Card, but the I/O memory (AUTOEXEC.IOM, ATEXEC@@.IOM) does not
need to be.

3. Simple Backup Operations
In Duplex Mode, the simple backup function can be executed only from the
active CPU Unit. Duplex initialization is not executed between the two CPU

CPU Units Section 2-4

Units after simple backup is performed. Therefore, after the data has been
read to the CPU Unit, turn the power OFF and back ON and then press the

2-4-3 CPU Unit Memory Map

The memory of CS1D CPU Units is configured in the following blocks.

• I/O Memory: The data areas accessible from the user program

• User Memory: The user program and Parameter Area (See note 1.)

The above memory is backed up using a CS1W-BAT01 Battery. If the battery
voltage is low, the data in these areas will not be stable.

The CPU Unit has a built-in flash memory, however, to which the user pro­gram and Parameter Area data is backed up whenever the user memory is
written to, including data transfers and online editing from a Programming
Device (CX-Programmer or Programming Console, data transfers from a
Memory Card, etc.). The user program and the Parameter Area data will thus
not be lost even if battery voltage drops.

For CS1D CPU Units, the Memory Card and a specified part of the EM Area
can be used to store files. All user programs, the I/O Memory Area, and the
Parameter Area can be stored as files.

Note 1. A Memory Card can be written up to approximately 100,000 times. (Each

write operation to the Memory Card must be counted regardless of the size
of the write.) Be particularly careful not to exceed the service life of the
Memory Card when writing to it from the ladder program.

2. The HMC-AP001 Memory Card Adapter is shown below.

3. For precautions regarding the use of Memory Cards, refer to 5-1 File Mem-

ory in the SYSMAC CS/CJ/NSJ Series Programmable Controllers Pro­gramming Manual (W394).

2-5-1 File Memory Functions in Duplex CPU Systems

Only the Memory Card in the active CPU Unit is accessed, whereas EM file
memory is accessed for both the active and standby CPU Units.

Using Memory Cards

Operation in a Duplex CPU
System

Memory Card functions can be executed in duplex only when the doing so is
enabled in the PLC Setup. In Duplex Mode, the same data that is written to
the Memory Card mounted in the active CPU Unit will also be written to the
Memory Card in the standby CPU Unit. No processing, however, is executed
during duplex initialization to match the data on the Memory Cards mounted
in the active and standby CPU Units. Therefore, before enabling duplex oper­ation for Memory Cards, make sure that the contents are the same for both of
the Memory Cards.

Data read from the Memory Card mounted in the active CPU Unit is used by
both the active and standby CPU Units, so this ensures that the data for the
two CPU Units will match.

functions.

Data is written to the Mem­ory Cards mounted in both

Data read from the Memory
Card in the active CPU Unit
is used by both CPU Units.

After the automatic transfer
at startup, duplex initializa­tion is executed between the
two CPU Units, and the user
program, parameters, and
I/O memory are matched.

Simultaneously with pro­gram replacement during
operation, duplex operation

Units after reading to the
CPU Units.

When referencing file memory-related
status, use the status for the active CPU
Unit (word A343).

There is no need to mount a Memory
Card or to set the DIP switch at the
standby CPU Unit.

After data is read from the Memory Card
by the simple backup operation, the CPU
Unit will be in PROGRAM mode. (CS­series specifications)

To begin the operation:

1. Turn OFF the power and set DIP
switch pins 7 and 8 on the CPU Units.
Then turn the power back ON.

2. Press the Initial Switch on the Duplex
Unit.

Note If pin 7 on the active CPU Unit is

turned ON, a duplex verification
error will be generated.

Using EM File Memory

Operation in a Duplex CPU
System

When a file is written to the EM file memory in the active CPU Unit in a Duplex
System, the same file is simultaneously written to the EM file memory in the
standby CPU Unit.

Note If EM file memory is specified for the active CPU Unit’s EM Area with the PLC

Setup, the same banks will be specified for the standby CPU Unit’s EM Area
by means of duplex initialization.
