We are working with an Allen Bradley PLC 5/60 with Remote I/O. The system currently has a 1/2 rack of I/O configured for rack 2 groups 0-3. Upon our DH trace we never saw such a thing. Yet the I/O Data file shows a "1" in the present bit for rack 2 group 0. If this is a half rack and it does exist shouldn't we have a 1 in each for both group 0 and group 2? We are only getting the single "1" back. Also none of the fault bits are present. I do believe that there is some misconfiguration here and it is preventing the BCM/BEM from switching to the secondary processor. Also, there are no errors on either the Block transfer Write or Block Transfer Read.
Thanks for your time.
