Station Monitoring

Station Monitoring provides a RealTime database (RTDB) table to store station configuration. This allows one or more remotes (Remote Terminal Units (RTUs), Programmable Logic Controllers (PLCs), flow computers) to be associated with the stations along the pipeline (measurement, pumping or compressor, storage, valve, telemetry, etc.) to which they belong.

Station Monitoring performs alarm "rollups" in a three-level hierarchy that starts with stations, and progresses upwards to sites, and, finally, regions. Administrators associate analog, rate, status, multistate, rtstring, and flowTotalConfig points with particular station records. Station records are then grouped under particular sites, and sites grouped under particular regions. Station Monitoring functionality consists of the following:

• Keeping track of the highest severity alarm conditions at stations, sites, and regions.

• Maintaining a count of alarms of each severity level at stations, sites, and regions.

When an alarm occurs, you can quickly drill down from region to site, from site to station, and, finally, to the station's point that caused the alarm.
