WARNING
Do not attempt to take any Unit apart or touch the inside of any Unit while the power is being supplied. Doing so may result in electric shock.
Do not touch any of the terminals or terminal blocks while the power is being supplied. Doing so may result in electric shock.
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 Programmable Controller or another external factor affecting the operation of the Programmable Control­ler. “Programmable Controller” indicates the CPU Unit and all other Units and is abbreviated “PLC” in this manual. Not doing so may result in serious acci­dents.
• Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits.
• The PLC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. 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.
• 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.
• Provide measures in the computer system and programming to ensure safety in the overall system even if communications errors or malfunctions occur in data link communications or remote I/O communications.
Confirm safety before transferring data files stored in the file memory (Mem­ory 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.
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.

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.
Confirm safety at the destination node before transferring a program, PLC Setup, I/O tables, I/O memory contents, or parameters to another node or changing contents of the any of these items. Transferring or changing data can result in unexpected system operation.
The CJ2 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 Holding Areas), however, is not written to flash memory.
The DM, EM, and Holding 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 Hold­ing Areas are used to control external outputs, prevent inappropriate outputs from being made whenever the Battery Error Flag (A402.04) is ON.
Tighten the terminal screws on the AC Power Supply Unit to the torque spec­ified in the operation manual. The loose screws may result in burning or mal­function.
Do not touch the Power Supply Unit when power is being supplied or immedi­ately after the power supply is turned OFF. The Power Supply Unit will be hot and you may be burned.
When connecting a personal computer or other peripheral device to a PLC to which a non-insulated Power Supply Unit (CJ1W-PD022) is mounted, either ground the 0 V side of the external power supply or do not ground the exter­nal power supply at all ground. A short-circuit will occur in the external power supply if incorrect grounding methods are used. Never ground the 24 V side, as shown below.

Application Precautions

Observe the following precautions when using a CJ-series PLC.
z Power Supply
• Always use the power supply voltages specified in the user’s manuals. An incorrect voltage may result in malfunction or burning.
• Exceeding the capacity of the Power Supply Unit may prevent the CPU Unit or other Units from starting.
• 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.
• 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, Option Boards, Pulse I/O Modules or any other Units.
• Assembling the Units.
• Setting DIP switches or rotary switches.
• Connecting cables or wiring the system.
• Connecting or disconnecting the connectors.
• When cross-wiring terminals, the total current for all the terminal will flow in the wire. Make sure that the current capacity of the wire is sufficient.
• Observe the following precautions when using a Power Supply Unit that supports the Replace­ment Notification Function.
• Replace the Power Supply Unit within six months if the display on the front of the Power Sup­ply Unit alternates between 0.0 and A02, or if the alarm output automatically turns OFF.
• Keep the alarm output cable separated from power line and high-voltage lines.
• Do not apply a voltage or connect a load exceeding the specifications to the alarm output.
• When storing the Power Supply Unit for more than three months, store it at −20 to 30°C and 25% to 70% humidity to preserve the Replacement Notification Function.
• If the Power Supply Unit is not installed properly, heat buildup may cause the replacement noti­fication signal to appear at the wrong time or may cause interior elements to deteriorate or become damaged. Use only the standard installation method.
• Do not touch the terminals on the Power Supply Unit immediately after turning OFF the power supply. Residual voltage may cause electrical shock.
• Observe the following precautions to prevent failure due to difference in electrical potential if the computer is connected to the PLC.
• Before connecting a laptop computer to the PLC, disconnect the power supply plug of the computer from the AC outlet. Residual current in the AC adaptor may cause difference in elec­trical potential to occur between the computer and the PLC. After you connect the computer and PLC, supply the power again from the AC adaptor.
• If the computer has an FG terminal, make the connections so that it has the same electrical potential as the FG (GR) terminal on the PLC.
• If the computer is grounded to a separate location, difference in electrical potential may occur depending on the grounding conditions.
z Installation
• Do not install the PLC near sources of strong high-frequency noise.
• 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.
CJ2 CPU Unit Hardware User’s Manual
21
• Be sure that the terminal blocks, connectors, Memory Cards, Option Boards, Pulse I/O Modules, expansion cables, and other items with locking devices are properly locked into place.
• The sliders on the tops and bottoms of the Power Supply Unit, CPU Unit, I/O Units, Special I/O Units, CPU Bus Units, and Pulse I/O Modules must be completely locked (until they click into place) after connecting to adjacent Units. The Unit may not operate properly if the sliders are not locked in place.
z Wiring
• Follow the instructions in this manual to correctly perform wiring.
• Double-check all wiring and switch settings before turning ON the power supply. Incorrect wiring may result in burning.
• Be sure that all terminal screws, and cable connector screws are tightened to the torque specified in the relevant manuals. Incorrect tightening torque may result in malfunction.
• Mount terminal blocks and connectors only after checking the mounting location carefully.
• 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.
• Do not apply voltages to the Input Units in excess of the rated input voltage. Excess voltages may result in burning.
• Always connect to a ground of 100 or less when installing the Units. Not connecting to a ground of 100 or less may result in electric shock. A ground of 100 or less must be installed when shorting the GR and LG terminals on the Power Supply Unit.
• 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.
• 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.
• 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 Link Adapter, CJ1W-CIF11 Converter, and Programmable Terminals (NV3W­M@20L). The external device or the CPU Unit may be damaged.
22
z Handling
• The Power Supply Unit may possibly be damaged if the entire voltage for a dielectric strength test is applied or shut OFF suddenly using a switch. Use a variable resistor to gradually increase and decrease the voltage.
• 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. Not doing so may result in burning.
• Make sure that the DIP switches and DM Area are set correctly before starting operation.
• After replacing the CPU Unit, a Special I/O Unit, or a CPU Bus Unit, make sure that the required data for the DM Area, Holding Area, and other memory areas has been transferred to the new Unit before restarting 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.
CJ2 CPU Unit Hardware User’s Manual
• Changing the present value of any word or any set value in memory.
• Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in mal­function, fire, or electric shock.
• Do not drop the PLC or subject abnormal vibration or shock to it.
• The life of the battery will be reduced if the PLC is left for a period of time without a battery installed and without power supply, and then a battery is installed without turning ON the power supply.
• Replace the battery as soon as a battery error occurs or as soon as the specified battery backup time expires. Be sure to install a replacement battery within two years of the production date shown on the battery's label.
• Before replacing the battery, turn ON power for at least 5 minutes before starting the replacement procedure and complete replacing the battery within 5 minutes of turning OFF the power supply. Memory contents may be corrupted if this precaution is not obeyed.
• If the Battery Error Flag is used in programming the application, confirm system safety even if the system detects a battery error before you replace the battery while the power is ON.
• 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 require that only an experienced engineer can replace the battery. Make sure that an experienced engineer is in charge of battery replacement. Follow the procedure for battery replacement given in this manual.
• Dispose of the product and batteries according to local ordinances as they apply.
• 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.)
• Unexpected operation may result if inappropriate data link tables or parameters are set. Even if appropriate data link tables and parameters have been set, confirm that the controlled system will not be adversely affected before starting or stopping data links.
• Write programs so that any data that is received for data link communications is used only if there are no errors in the CPU Units that are the sources of the data. Use the CPU Unit error informa­tion in the status flags to check for errors in the source CPU Units. If there are errors in source CPU Units, they may send incorrect data.
• All CPU Bus Units will be restarted when routing tables are transferred from a Programming Device to the CPU Unit. Restarting these Units is required to read and enable the new routing tables. Confirm that the system will not be adversely affected before transferring the routing tables.
• Tag data links will stop between related nodes while tag data link parameters are being trans­ferred during PLC operation. Confirm that the system will not be adversely affected before trans­ferring the tag data link parameters.
• If there is interference with network communications, output status will depend on the devices that are being used. When using devices with outputs, confirm the operation that will occur when there is interference with communications, and implement safety measures as required.
CJ2 CPU Unit Hardware User’s Manual

• 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 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.
• The user program and parameter area data in the CJ2 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.
• Check the user program and Unit parameter settings for proper execution before actually running them on the Unit. Not checking the program and parameter settings may result in an unexpected operation.
• When setting a Special I/O Unit or CPU Bus Unit in the I/O tables, carefully check the safety of the devices at the connection target before restarting the Unit.
• Do not turn OFF the power supply to the PLC when reading or writing a Memory Card. Also, do not remove the Memory Card when the BUSY indicator is lit. Doing so may make the Memory Card unusable. 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.
• When restoring data, carefully check that the selected data is the correct data to be restored before executing the restore operation. Depending on the contents of the selected data, the con­trol system may operate unexpectedly after the data is restored.
• Some Special I/O Units and CPU Bus Units operate with parameters stored in the CPU Unit (e.g., words allocated in DM Area, data link tables, or Ethernet settings). Information on restrictions will be displayed in the Information Area in the PLC Backup Tool if there are any restrictions for the selected CPU Bus Unit or Special I/O Unit. Check the restrictions, and then be sure to select both the CPU Unit and the CPU Bus Unit or Special I/O Unit when backing up or restoring data. The control system may operate unexpectedly if the equipment is started with the data backed up or restored without selecting both Units.
• Information on restrictions will be displayed in the Information Area in the PLC Backup Tool if the data to be stored includes a Unit that has restrictions on backup. Check the information on restric­tions and take the required countermeasures. The control system may operate unexpectedly when the equipment is operated after the data is restored
• Before restoring data during PLC operation, be sure that there will be no problem if PLC operation stops. If the PLC stops at an unexpected time, the control system may operate unexpectedly.
• Be sure to turn the PLC power supply OFF and then back ON after restoring data. If the power is not reset, the system may not be updated with the restored data, and the control system may operate unexpectedly.
• Data on forced status can be backed up but it cannot be restored. Perform the procedure to force­set or force-reset bits from the CX-Programmer as required before starting operation after restor­ing data that includes forced status. Depending on the difference in the forced status, the control system may operate unexpectedly.
• If a symbol or memory address (only symbols are allowed for ST programming) is specified for the suffix of an array variable in ladder or ST programming, be sure that the specified element number does not exceed the maximum memory area range. Specifying an element number that exceeds the maximum range of the memory area specified for the symbol will result accessing data in a different memory area, and may result in unexpected operation.
• If a symbol or address is specified for an offset in a ladder diagram, program so that the memory area of the start address is not exceeded when the offset is specified indirectly using a word address or symbol. If an indirect specification causes the address to exceed the area of the start address, the system will access data in other area, and unexpected operation may occur.

CJ2 CPU Unit Hardware User’s Manual
z External Circuits
• 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.
• Install external breakers and take other safety measures against short-circuiting in external wiring. Insufficient safety measures against short-circuiting may result in burning.

Regulations and Standards

Conformance to EC Directives
Applicable Directives
• EMC Directives
• Low Voltage Directive
Concepts
z 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.
* Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): CS Series: EN 61131-2 and EN 61000-6-2 CJ Series: EN 61000-6-2
* EMI (Electromagnetic Interference):
EN 61000-6-4 (Radiated emission: 10-m regulations)
z Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75 to 1,500 VDC meet the required safety standards for the PLC (EN 61131-2).
z Conformance to EC Directives
The CJ-series PLCs comply with EC Directives. To ensure that the machine or device in which the CJ-series PLC is used complies with EC Directives, the PLC must be installed as follows:
• The CJ-series PLC must be installed within a control panel.
• You must use reinforced insulation or double insulation for the DC power supplies connected to DC Power Supply Units and I/O Units.
• CJ-series PLCs complying with EC Directives also conform to the Common Emission Standard (EN 61000-6-4). 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.

1-1 Overview of CJ2 CPU Units

1-1-1 Overview

The SYSMAC CJ2-series CPU Units are multi-functional CPU Units that provide the following features.
z Fast, with Large Memory Capacity
Basic performance is faster and memory capacity has been increased to provide ample capability for machine control.
z Built-in EtherNet/IP Port (CJ2H-CPU6@-EIP and CJ2M-CPU3@ Only)
The CJ2 CPU Units support the EtherNet/IP open network as a standard feature. Universal Ethernet communications, such as data links between PLCs, message communications between PLCs, and FTP transfers, are all possible from a peripheral device connection.
z General-purpose Networks for Support Software Interface
Support Software and devices can be easily connected using commercially available cable to gen­eral-purpose networks via USB and EtherNet/IP ports. (The EtherNet/IP port is provided only on the CJ2H-CPU6@-EIP and CJ2M-CPU3@.)
z Tag Access (CJ2H-CPU6@-EIP and CJ2M-CPU3@ Only)
CJ2 CPU Units have a tag name server to manage tag names and I/O addresses. This enables access from external devices using tag names, without needing to know the I/O addresses.
z Synchronous Unit Operation (CJ2H CPU Unit with Unit Version 1.1 or Later)
The timing of processing performed by CPU Bus Units and Special I/O Units can be synchronized. This minimizes fluctuations in timing from input and processing to outputs, making it easier to ensure
application performance.
z Easier Programming
CJ2 CPU Units offer a highly readable programming environment, including features such as addressing DM and EM Area bits, setting address offsets, and using array variables.
z Improved Debugging
Online editing and data tracing have been improved, greatly increasing the efficiency of debugging.
1-2
z Increased Pulse I/O Capacity (CJ2M CPU Unit with Unit Version 2.0 or Later)
With the CJ2M CPU Units, optional Pulse I/O Modules can be mounted to enable pulse I/O for up to four axes.
z More Serial Communications Ports (CJ2M-CPU3@ Only)
With the standard CJ2M CPU Unit (CJ2M-CPU3@) you can add an RS-232C or RS-422A/485 Option Board to the standard-feature EtherNet/IP port to increase the number of serial communica­tions ports.

1-1-2 CJ2 CPU Unit Features

Fast, with Large Memory Capacity
z High-speed Processing
High-speed processing is possible for basic instructions (0.016 µs min. for CJ2H and 0.04 µs min. for CJ2M), special instructions (0.05 µs min. for CJ2H and 0.06 µs min. for CJ2M), and immediate refreshing (0.99 µs min. for CJ2H and 1.26 µs min. for CJ2M).
z Large Program Capacity
The CJ2 CPU Units provide a large program capacity of up to 400 Ksteps.
z Special Function Block Definition Area (CJ2M Only)
With a CJ2M CPU Unit, a special area called the FB Program Area is provided to store function block definitions. (The FB Program Area holds 20K steps.) This allows you to use function blocks to make program components and structures from previous programs while reducing the usage of the User Program Area. And any function block definitions that would exceed the FB Program Area are stored in the User Program Area.
z Large Data Memory Capacity
The CJ2 CPU Units provide a large EM Area capacity of up to 800 Kwords (25 banks).
z Up to 128 Cyclic Tasks
The user program can be divided into up to 128 tasks. Using smaller task programs makes it easier to structure programs and contributes to shorter cycle times.
z Enhanced Performance for Executing Interrupt Tasks (CJ2H CPU Units with
Unit Version 1.1 or Later)
With CJ2H CPU Units with unit version 1.1, overhead time for interrupt tasks is approximately 20% less than for unit version 1.0 even for normal usage. Also, by using High-speed interrupt function, it is possible to improve execution performance as shown below with certain restrictions.
• Greatly reduce overhead time for interrupt tasks (interrupt task startup time + return time to cyclic tasks).
Example: For I/O interrupt tasks, the time for normal operation is 37 µs but the time is 25 µs if
High-speed interrupt function is used.
• Minimum interval setting of 0.1 ms for one of Scheduled Interrupt Tasks (For unit version 1.0, the minimum interval is 0.2 ms.)

1 Overview
Tag Access (CJ2H-CPU6@-EIP and CJ2M-CPU3@ Only)
z Network Symbols (Tags) for Flexible Support of Program Changes
The CJ2 CPU Units support network symbols (tags). They have an internal tag name server that enables them to store tag names and addresses in advance in symbol tables in the CPU Units. Tags enable the following features.
Data links can be set using tags.
With data links on an EtherNet/IP network, send and receive areas can be specified using symbols rather than addresses. This enables flexible support for design changes by allowing the data link areas set by tags to remain unchanged, while simply changing the symbol tables that contain the tag names and addresses.
Data links enabled by names
Examples:
Inputs from a to b Inputs from c to d
EtherNet/IP

Access from host devices is enabled using tags.
Tags can be used for access from host devices, such as touch panel NS-series Programmable Ter­minals. This makes the creation of host screens and programs at devices such as PTs much more convenient.

1 Overview
Synchronous Unit Operation (CJ2H CPU Units with Unit Version 1.1 or Later)
z A CJ2 CPU Unit can synchronize the start of the processing performed by
CPU Bus Units and Special I/O Units to a specified cycle.
Synchronous data refreshing can be used between the CJ2H CPU Unit and Synchronous Units,* and the refreshed data can be used in operations in a synchronous interrupt task. This enables mul­tiaxis control with minimal fluctuations in the timing from inputs and processing to outputs. This pro-
vides support for motion applications that require precise timing, such as electronic cam control.
* Synchronous Units are CPU Bus Units and Special I/O Units that support the synchronous unit operation func-
tion. The following Synchronous Units are available as of July 2010: CJ1W-NC214/234/414/434 Position Control Units.

z Address offsets can be specified.
When an address is specified for an instruction operand, an offset can be specified in brackets after the address to offset it. For example, by setting a word address in brackets to specify the offset, the address can be dynamically specified according to the contents of that word.
Example W0.00[D0]: W0.00 is the starting address and the contents of D0 is the offset. If D0 is &3, then W0.03 is specified.
z Symbols can be specified for array variable subscripts.
By specifying symbols for array variable subscripts, elements can be dynamically specified accord­ing to the values of the symbols.
Example a[b]: The value of symbol b specifies the element for array variable a[ ].

1 Overview
z Create and Use Data Structures
With CX-Programmer version 9.0 or higher, data structures can be created and used. This enables easily using I/O memory in the CPU Unit as a database or for library data.
z Bit addresses can be used in the DM Area and EM Area.
Previously the DM Area and the EM Area could be addressed only by words, and bit addresses could not be specified. The work area for bits can now be expanded by enabling bit addresses in the DM and EM Areas.
For example, D10.00 specifies bit 00 of D10.
z The format for timer/counter PV refreshing can be selected individually for
each instruction.
Either BCD or binary can be selected individually for each instruction as the format for timer/counter PV refreshing. For example, the TIM (BCD) and TIMX (binary) instructions can be used together.

The optimum languages can be combined for structured programming.
Ladder diagrams, ST, and SFC languages can be freely combined in the user program. Being able to use the optimum languages for a particular process helps reduce the time involved in program­ming.

2-1-4 Configuration Units

Maximum Number of Units
A maximum of 10 Units can be connected to the CPU Rack for a CJ2 CPU Unit or to an Expansion Rack. There are no restrictions in the number of each model of Unit based on location.
Note A fatal error will occur and the CPU Unit will not operate if more than the allowable number of Units is con-
nected to a CJ2 CPU Rack or to an Expansion Rack.
Models of Configuration Units
The Configuration Units with which the CJ2 CPU Unit can exchange data are classified into three groups. The number of Units that can be mounted depends on the type of Unit.
Units Description
Basic I/O Units Basic I/O Units are used for discrete inputs and
outputs.
Special I/O Units Special I/O Units are more advanced than Basic
I/O Units. They support functions other than dis­crete inputs and outputs.
Examples: Analog I/O Units and High-speed Counter Units
Special I/O Units have a smaller area for exchanging data with the CPU Unit than CPU Bus Units (including Network Communications Units).
CPU Bus Unit CPU Units are advanced units that exchange
data with the CPU Unit via the CPU bus. Examples:
Network Communications Units and Serial Com­munications Units
CPU Bus Units have a larger area for exchang­ing data with the CPU Unit than Special I/O Units.
Unit identifica-
tion method
Identified by the CPU Unit accord­ing to mounting position.
Identified by the CPU Unit using unit numbers 0 to 95 set with the rotary switches on the front panel of the Unit.
Identified by the CPU Unit using unit number 0 to F set with the rotary switch on the front panel of the Unit.
Number of
mountable Units
Up to 40 Basic I/O Units can be mounted.
Up to 40 Special I/O Units can be mounted. (Depending on the model, more than one unit number is used for one Unit.)
Up to 16 CPU Bus Units can be mounted.

2-1-5 Calculating Unit Current Consumption

The amount of current/power that can be supplied to the Units mounted in a Rack is limited by the capacity of the Rack’s Power Supply Unit. Refer to the following tables when designing your system so that the total current consumption of the mounted Units does not exceed the maximum current for each voltage group and the total power consumption does not exceed the maximum for the Power Supply Unit.
For details on calculating the current consumption of Units, refer to 2-1-2 CPU Rack, 2-1-3 Expansion Racks, and 2-1-4 Configuration Units.
Maximum Current and Power Supplied by Power Supply Units
The following table shows the maximum currents and power that can be supplied by Power Supply Units in CPU Racks and Expansion Racks.
Note 1 When calculating current/power consumption in a CPU Rack, be sure to include the power required by the
CPU Unit itself, as well as the I/O Control Unit if one or more Expansion Racks is connected.
2 Be sure to include the power required by the I/O Interface Unit when calculating current/power consump-
tion in an Expansion Rack.

2-1-6 Calculating Power Consumption
The ambient operating temperature at the control panel for mounting a CJ-series PLC must be no higher than 55°C. This section describes how to calculate the power consumption of a CPU Rack for use in the thermal design of the control panel.
Calculating Power Consumption
Use the following equation to calculate the average power consumption (W) of a CJ-series CPU Rack.
2-1 Basic System Configuration
W = W_PLC
+ W_IO_ONOFF
Basic I/O Unit power consumption Basic PLC power consumption
z Basic PLC Power Consumption (W_PLC)
The basic PLC power consumption is calculated based on the overall power consumption of the PLC and the power conversion rate of the Power Supply Unit.
W_PLC = W_unit ÷ η
• W_unit: Total power consumption of Units mounted to the CPU Rack. For details on the current consump­tion and voltage of individual Units, refer to 2-1-4 Configuration Units.
η:
Power Supply Unit power conversion rate.
The rate is 70% for the CJ Series, so use “0.7” in the calculation.
z Basic I/O Unit Power Consumption (W_IO_ONOFF)
The Basic I/O Unit power consumption is the total consumption for the Input Units and the Output Units.
• Input Units
Rated input voltage × Input current × Number of input points
• Output Units
Residual voltage × Maximum load current × Number of output points
