How to resolve "Failed to connect to all servers" when viewing MOD300 system status
The connectivity server provides the MOD300 System Status to all the operator stations.
The system status can't seen for all users or some specific users.?
Check The DCN for Connectivity servers are working properly.
Are able to see MOD System status from MOD ES?
Check your user configuration
Check all the services are in service state..
If are still facing problem please share the error screen shot.
Are you sure 800xA Version 5.1 supports MOD300 ? When I check solutions bank I only see support for MOD300 in version 4 and version 5.0
(I have a customer site that needs to go to 800xA version 5.1 but they've been told its not available and are still stuck at 800xA version 4.1)
The MOD300 system status displays are "Engineering Displays" and seem to subscribe data a little differently from OPC based operator graphics.
Do you have any other issues with engineering displays ? - eg LoopFCM displays, Unit Displays, TCL Displays, TRIO diagnostics etc
