    Safety Precautions Definition of Precautionary Information The following notation is used in this manual to provide precautions required to ensure safe usage of a CJ-series PLC. The safety precautions that are provided are extremely important to safety. Always read and heed the information provided in all safety precautions.

  • Page 24

    Symbols The triangle symbol indicates precautions (including warnings). The specific operation is shown in the triangle and explained in text. This example indicates a precaution for electric shock. The circle and slash symbol indicates operations that you must not do. The specific operation is shown in the circle and explained in text.

  • Page 25

    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.

  • Page 26

    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 Hold- ing Areas are used to control external outputs, prevent inappropriate outputs from being made whenever the Battery Error Flag (A402.04) is ON.

  • Page 27

    • Observe the following precautions when using a Power Supply Unit that supports the Replace- ment Notification Function. • Replace the Power Supply Unit within six months if the display on the front of the Power Sup- ply Unit alternates between 0.0 and A02, or if the alarm output automatically turns OFF.

  • Page 28

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

  • Page 29

    • 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.

  • Page 30

    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.

  • Page 31

    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.

  • Page 32

    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.

    EN 61000-6-4 (Radiated emission: 10-m regulations) 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). Conformance to EC Directives The CJ-series PLCs comply with EC Directives.

    General-purpose Networks for Support Software Interface Built-in USB and EtherNet/IP Ports A commercially available USB cable can be used to connect to the PLC directly from a USB port on a personal computer. In addition, with the CJ2H-CPU6@-EIP or CJ2M-CPU3@, a PLC on the Ether- Net/IP network can be accessed via USB.

  • Page 48

    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.

  • Page 49

    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.

  • Page 50

    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.

    1 Overview Use Pulse I/O and Interrupt Inputs (CJ2M CPU Units Only) With the CJ2M CPU Units, up to two Pulse I/O Modules can be mounted. This enables input functions, such as normal inputs, interrupt inputs, high-speed counter inputs, and quick-response inputs, and output functions, such as normal outputs, pulse outputs, and variable duty factor pulse outputs.

Precautions for Safe Use Always use the standard installation method. A nonstandard installation will decrease heat dissi- pation, and may delay the replacement notification signal (in particular for Power Supply Units with Replacement Notification (CJ1W-PA205C)), or degrade or damage the internal elements.

    0x055F *1 The indicator status is the same for CPU errors and fatal errors, but they can be distinguished because a Programming Device can be connected when a fatal error occurs, but not when a CPU error occurs. *2 For details on fatal errors and non-fatal errors, refer to A-3 Fatal and Non-fatal Error Details.

  • Page 203: Handling Errors

    Then, make a preliminary determination of the cause of the error, confirm the cause, cor- rect the error, and take measures to ensure that it will not occur again. For all other errors, refer to A-3 Fatal and Non-fatal Error Details.

    When a CJ-series PLC is turned ON, the CPU starts cyclic servicing and enters RUN mode only after all Special I/O Units and CPU Bus Units have been detected. If the startup mode is RUN or MONITOR mode, the CPU will remain on standby until all Units have been detected.

    The Battery maintains the CPU Unit internal clock and the I/O memory data held in RAM while the main power supply is OFF.

    • Turn ON the power after replacing the battery for a CPU Unit that has been unused for a long time. Leaving the CPU Unit unused again without turning ON the power even once after the battery is replaced may result in a shorter battery life.

  • Page 238: Operation When Battery Is Exhausted Or Not Installed

    Operation is possible when the Battery is exhausted or not installed if the following two conditions both apply. • There is no need to save data in I/O memory. • There is no need to use initial settings in the DM/EM Area, or the initial settings are made by the user program. Additional Information You can use the function for automatic transfer from the Memory Card at startup to store data in I/O memory and the DM/EM Area even when the Battery is exhausted or not installed.

    • Bank 0 will be the EM current bank at startup. • Files will not be held in the EM file memory (EM data converted to flash memory) and the file memory function cannot be used. Make the EM file memory setting again in the PLC Setup, and format the EM file memory.

    (Tj) of the output transistor reaches the thermal shutdown temperature (Tstd), the out- put will turn OFF to protect the transistor from being damaged, and the alarm output bit will turn ON to light the ERR indicator. When the junction temperature (Tj) of the transistor drops down to the reset temperature (Tr), the ERR indicator will be automatically reset and the output current will start flowing.

    The CJ-series PLCs conforms to the Common Emission Standards (EN61000-6-4) of the EMC Direc- tives. 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.
