Hey everyone.  I am currently trying to send data from a PLC 5 to a SLC processor via a ControlLogix processor.  Neither the PLC 5 or SLC are on the same network.  Only the ControlLogix can communicate between the two.  I set up the MSG Block between the SLC and the ControlLogix without any issues.  However, when I set up the MSG block to read from the PLC 5 to the ControlLogix, I don't get a communications error but my INT isn't updating from the PLC 5.  When I trended the .EN and .DN bits for the MSG block, the DN bit never changes state and the EN bit only changes once in a while even though it is triggered from the same watchdog as the SLC MSG.  Not sure if maybe the CLX processor sees the PLC 5 over the ethernet but the PLC 5 is just too old to respond.  I checked other forums and everyone else got a communication error but I don't get one when I set it up.
