Hi all. Does anyone knows how to clear this error "xx55h" i tried a couple of times to clear the fault and it still faults when switching on run mode. When i disabled the slot by setting S:6/11 to '0' it works but i cannot use the input card anymore. Im starting to think that the card might be the problem and has to be replaced. Does anybody know what can i do so i can get it working again? plz see atatchment pic Thank you
