Dear all,
My CPU312 is in RUN state, RUN and DC5V LED's are green. Still there is no input or output. CP341 (RS422/485) is also installed in a rack with other I/O modules. I figured out that there is a power failure in all cards except main CPU because all the indicating lights are off only CPU is energized.
Any suggestion please??
