When you add the ProvisioningNwExt under the Supervisor’s NiagaraNetwork, five different device extensions are automatically created under each NiagaraStation component, as shown in Figure 57.
These device extensions are in addition to the standard extensions (Points, Histories, Alarms, Schedules, Users, Sys Def, Files) that exist for any NiagaraStation device.
These same extensions are also automatically included when you add a new station under the NiagaraNetwork in the Supervisor (providing the network has the ProvisioningNwExt).
The five provisioning extension types are:
-
Platform Connection — manages the platform connection between the Supervisor and the remote JACE running the station.
-
StationProxy — polls the station for system statistics.
-
Software — holds a “snapshot” of the current software versions installed on the JACE host.
-
Backup — enables the Supervisor to make backups of the station.
-
Licenses — enables the Supervisor to update licenses on the JACE running the station.
Although automatically created, you must (minimally) configure some properties in the Platform Connection provisioning extension.
