Appendix 2 I/O Signals; List Of I/O Signals; Execution Condition Of Output Signal - Mitsubishi Electric MELSEC iQ-R Series User Manual

Appendix 2
This section describes the I/O signals sent to or received from the CPU module. The I/O signal assignment for when the start
I/O number of the RJ71EIP91 is "0" is listed below.

List of I/O signals

The following tables list I/O signals. The device X is an input signal from the RJ71EIP91 to the CPU module. The device Y is
an output signal from the CPU module to the RJ71EIP91.

Do not use (turn on) any "use prohibited" signals as an input or output signal to the CPU module. Doing so
may cause malfunction of the programmable controller system.

Execution condition of output signal

The following lists the execution condition to turn on/off the output signal.
