Product Introduction
The ABB Bailey INSEM11 is a high-performance Sequence of Events (SOE) Master Module designed for critical event detection and timestamping in Distributed Control Systems (DCS). It plays a central role in capturing and organizing input events with millisecond resolution, making it ideal for post-event diagnostics, troubleshooting, and process optimization in industrial automation environments.
This module operates within ABB’s Infi 90 control system, working as the master controller that receives, organizes, and transmits time-critical events gathered from remote SOE slave modules. It significantly improves operational visibility by accurately logging status changes across systems and networks. This feature is particularly vital in high-stakes applications such as power generation, oil and gas, and process control plants.
