the rated range.

Is the capacity of the power supply module sufficient?

Calculate the current consumption of the CPU, I/O, intelligent 
function and other modules mounted on the base unit, and make 
sure that the capacity of the power supply module is enough.

Has a watchdog timer error occurred?

Reset the programmable controller CPU and check that the "RUN"

the normal mode. (Refer to Section 4.5.)

Is the setting value of the intelligent function module 
switch 5 other than "0"?

Set "0" for the intelligent function module switch 5 in GX
