[Design Precautions]

WARNING Configure safety circuits external to the programmable controller to ensure that the entire system

operates safely even when a fault occurs in the external power supply or the programmable controller. Failure to do so may result in an accident due to an incorrect output or malfunction. (1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting

operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured external to the programmable controller.

(2) When the programmable controller detects an abnormal condition, it stops the operation and all outputs are: Turned off if the overcurrent or overvoltage protection of the power supply module is activated. Held or turned off according to the parameter setting if the self-diagnostic function of the CPU

module detects an error such as a watchdog timer error. (3) All outputs may be turned on if an error occurs in a part, such as an I/O control part, where the

CPU module cannot detect any error. To ensure safety operation in such a case, provide a safety mechanism or a fail-safe circuit external to the programmable controller. For a fail-safe circuit example, refer to "General Safety Requirements" in the MELSEC iQ-R Module Configuration Manual.

(4) Outputs may remain on or off due to a failure of a component such as a relay and transistor in an output circuit. Configure an external circuit for monitoring output signals that could cause a serious accident.

In an output circuit, when a load current exceeding the rated current or an overcurrent caused by a load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an external safety circuit, such as a fuse.

Configure a circuit so that the programmable controller is turned on first and then the external power supply. If the external power supply is turned on first, an accident may occur due to an incorrect output or malfunction.

Configure a circuit so that the external power supply is turned off first and then the programmable controller. If the programmable controller is turned off first, an accident may occur due to an incorrect output or malfunction.

For the operating status of each station after a communication failure, refer to manuals for the network used. For the manuals, please consult your local Mitsubishi representative. Incorrect output or malfunction due to a communication failure may result in an accident.

When connecting an external device with a CPU module or intelligent function module to modify data of a running programmable controller, configure an interlock circuit in the program to ensure that the entire system will always operate safely. For other forms of control (such as program modification, parameter change, forced output, or operating status change) of a running programmable controller, read the relevant manuals carefully and ensure that the operation is safe before proceeding. Improper operation may damage machines or cause accidents.

[Design Precautions]

WARNING Especially, when a remote programmable controller is controlled by an external device, immediate

action cannot be taken if a problem occurs in the programmable controller due to a communication failure. To prevent this, configure an interlock circuit in the program, and determine corrective actions to be taken between the external device and CPU module in case of a communication failure.

Do not write any data to the "system area" and "write-protect area" of the buffer memory in the module. Also, do not use any "use prohibited" signals as an output signal from the CPU module to each module. Doing so may cause malfunction of the programmable controller system. For the "system area", "write-protect area", and the "use prohibited" signals, refer to the user's manual for the module used. For areas used for safety communications, they are protected from being written by users, and thus safety communications failure caused by data writing does not occur.

If a communication cable is disconnected, the network may be unstable, resulting in a communication failure of multiple stations. Configure an interlock circuit in the program to ensure that the entire system will always operate safely even if communications fail. Failure to do so may result in an accident due to an incorrect output or malfunction. When safety communications are used, an interlock by the safety station interlock function protects the system from an incorrect output or malfunction.

[Precautions for using Process CPUs] If the redundant system fails, control of the entire system may not be maintained depending on the

failure mode. The control may not be maintained in the following case either: An error in an extension base unit or in a module on an extension base unit is detected and causes a stop error of the control system, system switching occurs, and a similar error is detected and causes a stop error of the standby system (new control system). To ensure that the entire system operates safely even in these cases, configure safety circuits external to the programmable controller.

[Design Precautions]

WARNING [Precautions for using SIL2 Process CPUs] When the programmable controller compliant with SIL2 (IEC 61508) detects a fault in the external

power supply or itself, it turns off all outputs in the safety system. Configure an external circuit to ensure that the power source of a hazard is shut off by turning off the outputs. Failure to do so may result in an accident.

Configure short current protection circuits for safety relays and protection circuits, such as a fuse and breaker, external to the programmable controller.

When a load current exceeding the rated current or an overcurrent caused by a load short-circuit flows, modules operating in SIL2 mode detect an error and turn off all outputs. Note that if the overcurrent state continues for a long time, it may cause smoke and fire. To prevent this, configure an external safety circuit, such as a fuse.

When changing data and operating status, and modifying program of the running programmable controller from an external device such as a personal computer connected to the SIL2 Process CPU, configure an interlock circuit in the program or external to the programmable controller to ensure that the entire system always operates safely. In addition, before performing online operations, determine corrective actions to be taken between the external device and SIL2 Process CPU in case of a communication failure due to poor contact of cables.

Do not use any "use prohibited" signals of modules as an I/O signal since they are used by the system. Do not write any data to the "use prohibited" areas in the buffer memory of modules. For the "use prohibited" signals, refer to the user's manual for each module. Do not turn on or off these signals on a program since normal operations cannot be guaranteed. Doing so may cause malfunction of the programmable controller system.

[Design Precautions]

WARNING When a module operating in SIL2 mode detects an error in a safety communication path, it turns off

outputs. However, the program does not automatically turn off outputs. Create a program that turns off outputs when an error is detected in a safety communication path. If safety communications are restored with outputs on, connected devices may suddenly operate, resulting in an accident.

Create an interlock circuit which uses reset buttons so that the system does not restart automatically after executing safety functions and turning off outputs.

In the case of a communication failure in the network, the status of the error station will be as follows: (1) Inputs from remote stations are not refreshed. (2) All outputs from remote stations are turned off. Check the communication status information and configure an interlock circuit in the program to ensure that the entire system will operate safely. Failure to do so may result in an accident due to an incorrect output or malfunction.

Outputs may remain on or off due to a failure of an output module operating in SIL2 mode. Configure an external circuit for monitoring output signals that could cause a serious accident.

[Precautions for using Safety CPUs] When the safety programmable controller detects a fault in the external power supply or itself, it turns

off all outputs in the safety system. Configure an external circuit to ensure that the power source of a hazard is shut off by turning off the outputs. Failure to do so may result in an accident.

Configure short current protection circuits for a safety relay and protection circuits, such as a fuse and breaker, external to the safety programmable controller.

When a load current exceeding the rated current or an overcurrent caused by a load short-circuit flows, the CC-Link IE Field Network remote I/O module (with safety functions) detects an error and turns off all outputs. Note that if the overcurrent state continues for a long time, it may cause smoke and fire. To prevent this, configure an external safety circuit, such as a fuse.

When changing data and operating status, and modifying program of the running safety programmable controller from an external device such as a personal computer connected to the Safety CPU, configure an interlock circuit in the program or external to the safety programmable controller to ensure that the entire system always operates safely. In addition, determine corrective actions to be taken between the external device and Safety CPU in case of a communication failure during online operations due to poor contact of cables.

Do not use any "use prohibited" signals as a remote I/O signal since they are used in the system. Do not write any data to the "use prohibited" areas in the remote register. For the "use prohibited" signals, refer to the MELSEC iQ-R CC-Link IE Field Network User's Manual (Application). Do not turn on or off these signals on a program since normal operations cannot be guaranteed. Doing so may cause malfunction of the programmable controller system.

When the CC-Link IE Field Network remote I/O module (with safety functions) detects a CC-Link IE Field Network error, it turns off outputs. However, the outputs in a program are not automatically turned off. Create a program that turns off the outputs when a CC-Link IE Field Network error has been detected. If CC-Link IE Field Network is restored with outputs on, connected machines may suddenly operate, resulting in an accident.

[Design Precautions]

WARNING Ensure that the system does not restart automatically after executing safety functions and turning off

outputs. Create a circuit that does not allow the system to restart until an intentional start has been manually issued by an operator.

In the case of a communication failure in the network, the CPU module recognizes the communication destination station as an error station. The error station will be as follows: (1) All safety inputs from the error station to the CPU module are not refreshed. (2) All safety outputs from the error station to external devices are turned off because the CPU

module does not communicate with the error station. Check the communication status information and configure an interlock circuit in the program to ensure that the entire system will operate safely. Failure to do so may result in an accident due to an incorrect output or malfunction.

Outputs may remain on or off due to a failure of the CC-Link IE Field Network remote I/O module (with safety functions). Configure an external circuit for monitoring output signals that could cause a serious accident.

[Precautions for using redundant function modules] The optical transmitter and receiver of the redundant function module use laser diodes (class 1 in

accordance with IEC 60825-1/JIS C6802). Do not look directly at a laser beam. Doing so may harm your eyes.

[Design Precautions]

[Security Precautions]

CAUTION Do not install the control lines or communication cables together with the main circuit lines or power

cables. Doing so may result in malfunction due to electromagnetic interference. Keep a distance of 100mm or more between those cables.

During control of an inductive load such as a lamp, heater, or solenoid valve, a large current (approximately ten times greater than normal) may flow when the output is turned from off to on. Therefore, use a module that has a sufficient current rating.

After the CPU module is powered on or is reset, the time taken to enter the RUN status varies depending on the system configuration, parameter settings, and/or program size. Design circuits so that the entire system will always operate safely, regardless of the time.

Do not power off the programmable controller or reset the CPU module while the settings are being written. Doing so will make the data in the flash ROM and SD memory card undefined. The values need to be set in the buffer memory and written to the flash ROM and SD memory card again. Doing so also may cause malfunction or failure of the module.

When changing the operating status of the CPU module from external devices (such as the remote RUN/STOP functions), select "Do Not Open by Program" for "Opening Method" of "Module Parameter". If "Open by Program" is selected, an execution of the remote STOP function causes the communication line to close. Consequently, the CPU module cannot reopen the line, and external devices cannot execute the remote RUN function.

[Precautions for using SIL2 Process CPUs] Do not install the control lines or communication cables together with the main circuit lines or power

cables. Doing so may result in malfunction due to noise. Keep a distance of 100mm or more between those cables.

When selecting external devices to be connected to modules that operate in SIL2 mode, consider the maximum inrush current described in the user's manual for each module. Exceeding the maximum inrush current may cause malfunction or failure of the module.

[Precautions for using Safety CPUs] When selecting external devices to be connected to the CC-Link IE Field Network remote I/O module

(with safety functions), consider the maximum inrush current described in the CC-Link IE Field Network Remote I/O Module (With Safety Functions) User's Manual. Exceeding the maximum inrush current may cause malfunction or failure of the module.

WARNING To maintain the security (confidentiality, integrity, and availability) of the programmable controller and

the system against unauthorized access, denial-of-service (DoS) attacks, computer viruses, and other cyberattacks from external devices via the network, take appropriate measures such as firewalls, virtual private networks (VPNs), and antivirus solutions.

Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

[Wiring Precautions]

[Wiring Precautions]

WARNING Shut off the external power supply (all phases) used in the system before installation and wiring.

Failure to do so may result in electric shock or cause the module to fail or malfunction. After installation and wiring, attach a blank cover module (RG60) to each empty slot and an included

extension connector protective cover to the unused extension cable connector before powering on the system for operation. Failure to do so may result in electric shock.

CAUTION Individually ground the FG and LG terminals of the programmable controller with a ground resistance

of 100 ohms or less. Failure to do so may result in electric shock or malfunction. Use applicable solderless terminals and tighten them within the specified torque range. If any spade

solderless terminal is used, it may be disconnected when the terminal screw comes loose, resulting in failure.

Check the rated voltage and signal layout before wiring to the module, and connect the cables correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause fire or failure.

Connectors for external devices must be crimped or pressed with the tool specified by the manufacturer, or must be correctly soldered. Incomplete connections may cause short circuit, fire, or malfunction.

Securely connect the connector to the module. Poor contact may cause malfunction. Do not install the control lines or communication cables together with the main circuit lines or power

cables. Doing so may result in malfunction due to noise. Keep a distance of 100mm or more between those cables.

Place the cables in a duct or clamp them. If not, dangling cables may swing or inadvertently be pulled, resulting in malfunction or damage to modules or cables. In addition, the weight of the cables may put stress on modules in an environment of strong vibrations and shocks. Do not clamp the extension cables with the jacket stripped. Doing so may change the characteristics of the cables, resulting in malfunction.

Check the interface type and correctly connect the cable. Incorrect wiring (connecting the cable to an incorrect interface) may cause failure of the module and external device.
