INSEM01 | ABB | Sequence of Events Master Module

Description

The ABB Bailey INSEM01 is a specialized Sequence of Events (SOE) Master Module designed for the Symphony Harmony and Infi 90 distributed control systems. Its primary role is to provide ultra-high-resolution time-stamping for discrete events across the plant. 

Specifications

• Model Number: INSEM01
• Time Resolution: 1 millisecond.
• Capacity: Manages up to 8 Sequence of Events Input Slave modules.
• Storage: Internal buffer for storing event logs before they are uploaded to the Human Machine Interface (HMI).
• Clock Sync: Synchronizes with a system-wide Master Clock or GPS source to ensure time consistency across the network.
• Communication: Operates on the standard Harmony/Infi 90 Slave Bus.
• Power Requirements: +5 VDC @ 1.5 Amps (typical).

Features

• Post-Mortem Analysis: Provides the precise chronological data needed to analyze why a system tripped, distinguishing between events that happened only milliseconds apart.
• GPS Integration: Supports high-accuracy time synchronization with external IRIG-B or GPS time sources to maintain microsecond accuracy relative to real-world time.
• Event Buffering: Features local non-volatile memory to store thousands of events, preventing data loss during periods of high network traffic or communication interruptions.
• Master/Slave Coordination: Acts as the "manager" for INSET series slave modules, polling them at high speeds and collating their data into a single, cohesive event list.
• System-Wide Alignment: Ensures that every INSEM01 module in the plant is perfectly synchronized, allowing for a plant-wide timeline of events across different control racks.
• Advanced Filtering: Includes software-configurable "chatter" filters to ignore rapidly oscillating inputs that might otherwise saturate the event log.
