I was recently updating the firmware revision of a CompactLogix L20 processor when someone working near me cut the power to the PLC. When I tried to set things up again I can no longer communicate to the device using RSLinx nor can I continue to update the firmware.
I tried taking out the battery for 20mins or so but it didn't seem to help.
Every time I start I just get a red light on the OK LED and nothing else...is there any way I can fix this?
