Operation and Test
Self-diagnostic function
When the power of the CPU module is turned on, the self-diagnostic function to check for errors starts in the module. The
CPU module boots when there is no error with the hardware, parameters and program.
When there are no errors, the module enters the RUN status (the P.RUN LED turns on) in response to the RUN instruction
(Page 114 Running, Stopping, and Resetting). If any error is detected, the "ERR" LED flashes or lights up.
Monitoring and debugging
The ON/OFF status of PLC's devices, current values or set values can be monitored or changed by using engineering tools.
For details, refer to GX Works3 Operating Manual.
