Last night I tryed adding a 1762-OW16 output card to a Micrologix 1400 PLC. I was unsuccessful. If I tryed to read I/O configuration it would not see the expansion. If I picked the card from the list and downloaded, it faulted out that the I/O did not match. I looked up the card on the AB website to be sure it is compatible, and it is. The PLC is less than 6 months old. I also tryed a different card but it had the same results. Does anyone have any info on this problem?
