Hi friends
I encounter with some unwanted faults in our system
Please guide me to fix it
In our company, we use S7 400 H PLC with redundancy
Nowadays,we see some faults that its reason is not clear to us.
REDF (redundant fault) and BUS2F LEDs of CPUs and BUS1F of IM153 are simultaneous ON.
Could you please help me to know exact reason of this event and solution toward solve it?
With best regards
