Sync-in and –out user device extension configurations
Typically, a Supervisor station sends user data and multiple remote controller stations receive the synchronized data. Data in and out is flexible. This topic provides examples of how to configure the Sync In Enabled and Sync Out Enabled properties of the user device extension of NiagaraStations.
Supervisor and subordinate configuration
Multi-tier configuration
It is possible to have a multi-tier network user synchronization configuration with a single master Supervisor host and several subordinate Supervisor hosts, each with multiple subordinate remote controller stations. In the NiagaraNetwork of each subordinate Supervisor station, Sync In Enabled would be set to true. This sends user data from the master station to the single NiagaraStation in the subordinate Supervisor that proxies the master Supervisor.
In the subordinate Supervisors’ other NiagaraStations (the ones that proxy remote controller stations), Sync Out Enabled is set to true. In this configuration, each subordinate Supervisor station is both a receiver and a sender of user data.
