Product Overview
The ABB Bailey INSEM11 Event Sequence Main Module is a dedicated Sequence of Events (SOE) processing module used in ABB INFI 90 / Network 90 distributed control systems (DCS). It serves as the central event management unit responsible for collecting, organizing, timestamping, and storing operational events generated throughout the control system.
The module helps plant operators and maintenance personnel accurately analyze alarms, equipment status changes, trips, and process disturbances by preserving the precise sequence in which events occur.
