I just encountered something strange on a system using NET-ENI's.
The main PLC, that does all the messaging, is a SLC5/05. It messages to 2 SLC5/03's and a ML1400. The message read and writes to one of the NET-ENI's fail every time - but I can see it in RSLinx and go online with it, monitor the 5/03 and do online edits OK. So the NET-ENI seems to be working correctly.
For a test I swapped the 2 NET-ENI's between the 5/03's and changed the MSG addresses to match. Now the message fails followed the NET-ENI. Both of the NET-ENI's are 161-NET-ENI Ser D Rev B FRN 3.22 powered off external 24V power supplies - that tested good. Both connect to the network at 100MB. Both 5/03's are set to 19200 baud with the other settings (stop, parity, CRC, etc,) normal DF-1.
Has anyone had any problem like this before, and hopefully resolved it?
