CJ2 CPU Unit Hardware User’s Manual
WARNING
Do not attempt to take any Unit apart 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 PLC or another external factor affecting the PLC operation. 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. As a countermeasure for 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.
• When the 24-VDC 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.
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.

CJ2 CPU Unit Hardware User’s Manual
WARNING
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 force-set 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.

CJ2 CPU Unit Hardware User’s Manual
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 to another node or changing contents of the I/O memory area. Doing either of these without confirming safety may result in injury.
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 screws on the terminal block of the AC Power Supply Unit to the torque specified in the user’s 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.
Be careful when connecting personal computers or other peripheral devices to a PLC to which is mounted a non-insulated Unit (CS1W-CLK1@/5@(-V1) or CS1W-ETN01) connected to an external power supply. A short-circuit will be created if the 24 V side of the external power supply is grounded and the 0 V side of the peripheral device is grounded. When connecting a peripheral device to this type of PLC, either ground the 0 V side of the external power supply or do not ground the external power supply at all.

CJ2 CPU Unit Hardware User’s Manual
Caution
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. For example, write the program so that pro­cessing is executed only when the indirect specification is within the memory area range by using a symbol comparison instructions or an IF statement.
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. For example, write the program so that processing is executed only when the indirect specification does not cause the final address to exceed the memory area by using an input comparison instruction or other instruction.
If a 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.

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, 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.
• Whe 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 a 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.
22
CJ2 CPU Unit Hardware User’s Manual
• Be sure that the connectors, terminal blocks, expansion cables, and other items with locking devices are properly locked into place. Improper locking may result in malfunction.
• The sliders on the tops and bottoms of the Power Supply Unit, CPU Unit, I/O Units, Special I/O Units, and CPU Bus Units 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. It may not be possible to achieve proper functionality if the sliders are not locked.
• Always attach the End Cover that comes with the CPU Unit to the right end of the CPU Rack. The PLC will not operate correctly if the End Cover is not attached.
z Wiring
• Wire all connections correctly.
• 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.
• Do not apply a force exceeding 100 N to the terminal block when tightening it.
• Mount Units only after checking terminal blocks and connectors completely.
• 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.
• 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.
• 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 or CJ1W-CIF11 Adapter. The external device or the CPU Unit may be dam­aged.
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.
23
CJ2 CPU Unit Hardware User’s Manual
• Make sure that the required data for the DM Area, Holding Area, and other memory areas has been transferred to a CPU Unit that has been replaced 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.
• 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.
• 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.
• When transporting or storing Units or Board, static electricity can destroy LSIs or ICs. Cover the PCBs with a conductive material and maintain the specified 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.
• The life of the battery will be reduced if a CPU Unit 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.
• 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.
• 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.
• 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 allowing the CPU Bus Units to be reset.
• 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.
• A battery is mounted to a CJ-series CPU Unit when the Unit is shipped from the factory. Also, the time is set on the internal clock. It is thus not necessary to clear memory and set the clock before using a CJ-series CPU Unit. This point differs from the CS-series CS1 CPU Units.
24
CJ2 CPU Unit Hardware User’s Manual
• 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.
• A CS1 or CJ1 CPU Unit program file (.OBJ) cannot be transferred directly to a CJ2 CPU Unit using a Memory Card. It must first be converted for use with a CJ2 CPU Unit using the CX-Pro­grammer.
z External Circuits
• Interlock circuits, limit circuits, and similar safety measures in external circuits (i.e., not in the Pro­grammable Controller) must be provided by the customer.
• 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.
• 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.)
• Install external breakers and take other safety measures against short-circuiting in external wiring. Insufficient safety measures against short-circuiting may result in burning.
• Dispose of the product and batteries according to local ordinances as they apply.
• 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.

z High-speed Processing
High-speed processing times of 0.016 µs for basic instructions, 0.048 µs for special instructions, and
0.99 µs for immediate refreshing, are now possible.
z Large Program Capacity
The CJ2 CPU Units provide a large program capacity of up to 400 Ksteps.
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.
The CJ2 CPU Units provide as standard equipment a built-in EtherNet/IP port that supports the same FINS Ethernet functions as an Ethernet Unit (including features such as a FINS server and time coordi­nation) as well as the EtherNet/IP open network.
z High-speed, High-capacity Data Links with User-set Refresh Cycles
The CJ2 CPU Units provide high-speed, high-capacity data links, and refresh cycles can be set indi­vidually for each data link area.

z Built-in USB and EtherNet/IP Ports
Commercially available USB cable can be used to connect directly from a USB port on a personal computer. In addition, a PLC on the EtherNet/IP network can be accessed via USB.
z Prevent Connecting to the Wrong PLC by Using PLC Names from Support
Software
A user-set PLC name can be recorded in a CJ2 CPU Unit. When using Support Software to connect online to a PLC, verification of the PLC name prevents incorrect connections from the Support Soft­ware.
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.
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.

Automatic tag allocation makes it unnecessary to know the addresses.
Automatic allocation of tags in the high-capacity EM Area, using automatic address allocation in CX­Programmer symbol tables, enables data link design and access from host devices without having to pay attention to addresses.
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[ ].
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.

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.
In addition, ladder diagrams and ST language can be freely used for function blocks (FBs) in ladder diagrams and ST programs, and for transition and action programs in SFC. This feature makes it possible to optimize structured programming.
z Reduced Effect on Cycle Time from Online Editing
The additional cycle time due to online editing has been reduced to approx. 1 ms, minimizing the effects on equipment operation during debugging.
z Fast, High-capacity Data Tracing
Up to 32 Kwords of data can be traced (8 time more than previously), with ample trigger conditions, and data can be traced continuously for long periods of time.

*2 Large Forward Open (CIP optional specification) must be supported in order for 505 to 1,444 bytes to be used as the data
size. Application is supported between CS/CJ-series PLCs. When connecting to devices from other manufacturers, make sure that the devices support the Large Forward Open specification.
*3 If the maximum number is exceeded, refreshing will require more than one CPU Unit cycle.
*4 When changing parameters, however, the EtherNet/IP port where the change is made will be restarted. In addition, a tim-
eout will temporarily occur at the other node that was communicating with that port, and it will then recover automatically.

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.
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.

Basic I/O Units Basic I/O Units are used for discrete inputs and
outputs.
Identified by the CPU Unit accord­ing to mounting position.
No limit
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).
Identified by the CPU Unit using unit numbers 0 to 95 set with the rotary switches on the front panel of the Unit.
Up to 96 Special I/O Units can be mounted.
(Depending on the model, 1 to 4 unit numbers are used for one Unit.)
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.
Identified by the CPU Unit using unit number 0 to F set with the rotary switch on the front panel of the Unit.
Up to 15 CPU Bus Units can be mounted.

CJ2 CPU Unit Hardware User’s Manual
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.
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.

CJ2 CPU Unit Hardware User’s Manual
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.
Use the following equation to calculate the average power consumption (W) of a CJ-series CPU Rack.
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 ???.
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
Note For the CJ Series, calculate the residual voltage at 0.1 V.

z Basic I/O Unit Power Consumption (W_IO_ONOFF)
W_IO_ONOFF = 24 V × 0.0041 A x 128 points + 0.1 × 0.3 A × 128 points = 16.43 W

• There is no priority to the order in which the errors are displayed. All of the errors are displayed repeatedly in sequence.
Left/Right Dot LEDs
If an error occurs at multiple devices for which the rightmost 8 bits in the IP addresses are the same, this is indicated by the dots on the right side in display on the target devices.
The following examples show the displays for multiple errors.
• d6 errors (failure to connect) have occurred in communications with IP address 10.0.1.8.
• d6 errors (failure to connect) have occurred in communications with IP address 10.0.2.8.
The unit number and node address for the CJ2 CPU Unit built-in EtherNet/IP port are set using the rotary switches. The unit number and node address are allocated in the same way as for a CPU Bus Unit. According to the unit number that is set, words are automatically allocated in the CIO Area and DM Area. For details, refer to the CJ2 CPU Unit Software User’s Manual (Cat. No. W473).
z Setting the Unit Number
Set a unique unit number for the CJ2 CPU Unit built-in EtherNet/IP port. The same unit number can­not be used by any other CPU Bus Unit connected to the CJ2 CPU Unit.
Use a small screwdriver to make the setting, and be sure not to damage the rotary switch. The unit number is factory-set to 0.
Precautions for Correct UsePrecautions for Correct Use
• Always turn OFF the PLC’s power supply before setting the unit number.
• When setting the unit number for the first time or when changing the setting, create the PLC’s I/O tables.
z Node Address Setting Switches
Set a FINS address for the built-in EtherNet/IP port. With the FINS communications service, multiple EtherNet/IP Units (including the CJ2 Unit built-in EtherNet/IP port) connected by Ethernet are identi­fied by their node addresses. Using the node address switches, set a unique node address in hexa­decimal. The same node address cannot be used by any other EtherNet/IP Unit or Ethernet Unit connected on the same Ethernet network.

As long as it does not duplicate any other address, the node address can be set from 01 to FE (1 to 254 in decimal).
Note The node address is factory-set to 01. With the default setting, the values set on these switches become the
last two digits of the built-in EtherNet/IP port’s IP address.
The default IP address is 192.168.250.node_address. With the factory-set node address of 01, the default IP address is 192.168.250.1.
The node address can be set to any number in the setting range (01 to FE), as long as the same address is not set on another node in the network.
Precautions for Correct UsePrecautions for Correct Use
• Always turn OFF the PLC’s power supply before setting the unit number.
• When setting the unit number for the first time or when changing the setting, create the PLC’s I/O tables.
Additional Information
• If the node address setting is changed during operation, the MS Indicator will flash red.
z Relationship with IP Address
When using the automatic generation method (dynamic/static) for IP address conversion, the right­most byte of the IP address that is set for the built-in EtherNet/IP port must be set to the same value as the node address. If it cannot be set to the same value as the node address, then the address conversion method must be set to the IP address table method or the IP address + automatic gener­ation method. For details, refer to the CS/CJ Series EtherNet/IP Units Operation Manual (Cat. No. W465).

*1 The AC and DC values above are given for a cold start, and the AC values are at room temperature. The AC inrush con-
trol circuit uses a thermistor element with a low-temperature current control characteristic. If the ambient temperature is high or the PLC is hot-started, the thermistor will not be sufficiently cool, and the inrush current given in the table may be exceeded by up to twice the given value. When selecting fuses or breakers for external circuits, allow sufficient margin in shut-off performance. The DC inrush control circuit uses a capacitor-charging delay circuit. If the power is OFF for only a short time for a hot-start, the capacitor will not sufficiently charge and the inrush current given in the table may be exceeded by up to twice the given value.
*2 Supported only when mounted to CPU Rack.
*3 Disconnect the 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.
*4 Change the applied voltage gradually using the adjuster on the Tester. If the full dielectric strength voltage is applied or
turned OFF using the switch on the Tester, the generated impulse voltage may damage the Power Supply Unit.
*5 Maintain an ambient storage temperature of -25 to 30°C and relative humidity of 25% to 70% when storing the Unit for
longer than 3 months to keep the replacement notification function in optimum working condition.
*6 CJ1W-PD022 is not insulated between the primary DC power and secondary DC power.
*7 Internal components in the Power Supply Unit will deteriorate or be damaged if the Power Supply Unit is used for an
extended period of time exceeding the power supply output capacity or if the outputs are shorted.
