12.2.6 When the "RUN" LED flashes

If the "RUN" LED flashes, follow the steps below.
When the programs or parameters are written into the CPU module during STOP status
and then the RUN/STOP/RESET switch is set from STOP to RUN, the "RUN" LED of the
CPU module flashes.
Although this status does not mean the CPU module error, the CPU module stops the
operation. To set the CPU module into RUN status, reset the CPU module using the RUN/
STOP/RESET switch.
With this setting, the "RUN" LED turns on.
The "RUN" LED still flashes even when the RUN/STOP/RESET switch is set from RUN to
STOP and then to RUN after flashing.
