Chapter 4 Choosing a Device for a Master Station
Very large applications can also require submaster stations, which:
• gather data from the remote stations within a region.
• support local operator interface for the region.
• support logging of alarms and events.
• communicate remote station data and support control commands.
• interface with a larger, host master station.
In the illustration below, a submaster station controls remote sites within a
region.
