Verify station-to-station communications

Ideally, station-to-station communications between the platforms converted to N4.0 and all others resume after the upgrade. That is, communications between the Supervisor and controller stations, via the NiagaraNetwork. Supervisor communications between any JACE stations which remain at AX-3.8 should also resume. (Note this assumes all station names remained unchanged.)

However, in some cases you may need to take additional steps to restore communications, working in the N4.0 Supervisor stations and/or controller stations ( N4.0 JACEs, and if applicable, AX-3.8 too).

NOTE: If configuration of any AX-3.8 JACE station is required, say to edit “client connection” properties of the NiagaraStation that represents the N4.0 Supervisor, need to use Workbench for this.

Some variation of the following sequence may be required:

In Workbench, re-open the Supervisor station and go to the Station Manager view of its NiagaraNetwork.
If new JACE controllers were added (not migrated) there will not be an existing station child for them—you need to select and add them.
For each NiagaraStation in the Supervisor station’s NiagaraNetwork, verify that communications report {ok}. The status of all stations in the network should be {ok}.
In cases where secure communication (Foxs) is being used with the default self-signed certificates, it may be necessary to go to the Supervisor’s CertManagerService platform service, and perform other actions.

The figure above shows allowed hosts exceptions for migrated controllers that need approval. This may not be necessary, if previously-exported TLS/SSL certificates were imported before commissioning.
In a station connection to each JACE controller, go to the Station Manager view of its NiagaraNetwork, and verify communications to the Supervisor are {ok}.
Again, if Foxs (TLS/SSL) is being used by a Hotspot JACE station back to the Supervisor (and possibly other JACE stations) you may need to go to the JACE station’s CertManagerService platform service, and perform other actions.
While working in remote JACE stations, after verifying NiagaraNetwork communications back to the Supervisor are {ok}, verify other “inter-network” configuration is valid. For example, verify the correct NiagaraStation component (representing the Supervisor) is referenced in the appropriate StationRecipient component, under the station’s AlarmService. Typically, this is necessary only if station names were changed when migrating.
