We are currently having an intermittant momentary loss of communications on one of our HMI servers (Cimplicity ver. 5.5). The comms are lost to all 4 MKVs on the Arcnet, but not to any of the 4 PLCs that use the Ethernet. The Diagnostic Couters / StageLink reconfiguration counters do not increase when this happens (approx. 3 times every 24 Hrs), so this kind of rules out a hardware issue.
My main question is, if the MKV <C> has a configurable baud rate and how do I find out what it is set for. The Cimplicity Workbench Equiptment / Ports / MKV / Baud rate is configurable and I am speculating that these should be matched. Also we did replace the PCI Arcnet card in the server in question although I am not a fan of random board swapping as a troubleshooting technique.
The network in question is 4 MKVs in TMR w/ 2 servers, 2 viewers and 1 PI Historian. The other server has rock solid comms. The difference between the 2 servers is their location on the network. The server w/ comms probs. is ~ 3/4 miles away from the other server connected by fiber via Modhubs. The network topology is similar to the example in the MKV Application manual (GEH-6195F) page 9-8.
Thanks for the help.
