I had a 1734 AENT module that I wanted to move from a PLC that had very little downtime (runs the main process of my plant) to a PLC that I could take offline and test trial code on.
This 1734 AENT module only has one IB4 card running on it.
PLC 1 is a 1756 L63 Firmware revision 17
PLC 2 is a 1756 L61 Firmware revision 19
I started the transfer process by inhibiting the AENT module in PLC 1 and then adding it to PLC 2. This is where the problem started. PLC 2 can poll information from the AENT and know if it is owned and configured but gets a comm fault 16#2023 and will continually switch between an internal state of unconnected and not being owned to an internal state of Run Mode and being owned.
Now to try and resolve this I tried power cycling, restarting the AENT from Logix5000, Upgrading to a AENTR, and changing the IP address. But the problem still persists.
I am thinking there is some lingering connection to PLC 1 that is kicking PLC 2 off. Is there some way to clear this or is something else happening here?
