Event Manager

Event Manager is a Windows service that communicates with the Foxboro DCS subsystems. The Event Manager receives all Foxboro DCS alarms and stores them in the Batch Historian.

Event Manager uses either the LOOPID value or equipment allocation to determine the batch identification for alarms. During batch processing, Event Manager compares the LOOPID field of the alarm message with the current list of batches in the schedule.

If there is a match, the alarm is considered a batch alarm. An Alarm ID is then assigned to the alarm, and it is logged to the Batch Historian along with its Batch Identification (Campaign, Lot and Batch ID). If the LOOPID value does not match a Batch ID in the schedule, Event Manager searches the Link database for the Compound:Block name.

If there is a match, the alarm is considered a batch alarm. Event Manager determines the equipment name (Unit, Connection or Segment) from the Link database and then, using Equipment Allocation information, determines the Batch ID. An Alarm ID is assigned to the alarm and it is logged to the Batch Historian along with its Batch Identification (Campaign, Lot and Batch ID). If the Compound:Block name is not found in the Link database, the alarm is not considered to be a batch alarm and is discarded.
