[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.
For the operating status of each station after a communication failure, refer to manuals relevant to the network. Incorrect output or malfunction due to a communication failure may result in an accident.

[Design Precautions]
WARNING
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.
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.
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.
To maintain the safety of the programmable controller system against unauthorized access from external devices via the network, take appropriate measures. To maintain the safety against unauthorized access via the Internet, take measures such as installing a firewall.
When a communication error occurs on the PROFIBUS-DP network, the operating status of each station is as shown below ((1), (2), or (3)). Check the communication status information ('Diagnostic information detection signal' (X1), 'Diagnostic information area (for mode 3)' (Un\G23072 to Un\G23321), and 'Extended diagnostic information area (for mode 3)' (Un\G23328 to Un\G23454)) 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. (1) The DP-Master holds the input data before a communication error occurs. (2) When the DP-Master has gone down, the output status of each DP-Slave is dependent on the
parameter setting.
(3) When a DP-Slave has gone down, the output status of other DP-Slaves is dependent on the
parameter setting of the DP-Master.
When a stop error has occurred in the CPU module, the status of the RJ71PB91V is as shown below. (1) When "Output Mode upon CPU Error" is set to "Clear".
• Data exchanges with DP-Slaves are interrupted.
• Output data in the buffer memory of the RJ71PB91V are cleared and are not transmitted.
• Input data received from DP-Slaves when a stop error has occurred in the CPU module are held in the buffer memory of the RJ71PB91V.
(2) When "Output Mode upon CPU Error" is set to "Hold".
• Data exchanges with DP-Slaves are continued.
• Output data in the buffer memory of the RJ71PB91V are held the value when a stop error has occurred in the CPU module and are transmitted to DP-Slaves.
• The buffer memory of the RJ71PB91V is updated by input data received from DP-Slaves.

[Design Precautions]
CAUTION
Do not install the control lines or communication cables together with the main circuit lines or power cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction due to noise.
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 in Program" for "Open Method Setting" of "Module Parameter". If "OPEN in 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.

(3)
RJ71PB91V
To make full use of the functions of the RJ71PB91V and to configure a highly reliable system, the external wiring should be
resistant to noise.
The following are precautions for the external wiring of the RJ71PB91V.
• Do not route the communication cable of the RJ71PB91V near the main circuit, power cable, or load cable other than that
of the programmable controller. In addition, do not bundle those cables together. Otherwise the RJ71PB91V may be
affected by noise or surge induction.
• Place the PROFIBUS cable as far away from the I/O module cable as possible.
6
(1) Power supply module (2) Input module wiring (3) Output module wiring (4) Shield jacket (5) PROFIBUS cable
• As a rule, to use the RJ71PB91V, ground the FG and LG terminals of the power supply module of the programmable
controller.
• Place the communication cables and power cables connected to the module in a duct or clamp them. If not, dangling cable
can swing or inadvertently be pulled, resulting in damage to the module or the cable or malfunction due to poor contact.
• Do not touch the core of the cable-side or module-side connector, and protect it from dirt or dust. If oil from your hand, dirt,
or dust is attached to the core, transmission loss can increase, causing communication failures.
• Securely connect the connector to the module.
• Tighten the screws within the specified torque range. Undertightening can cause drop of the screw, short circuit, or
malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
• When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable with connector, hold
the connector part of the cable. Pulling the cable connected to the module may result in malfunction or damage to the
module or cable.
