Description
Overview
The INSEM01 from ABB Bailey is a Sequence of Events Master module developed for use within ABB Infi 90 and Net 90 distributed control systems. This module is designed to collect, manage, and process sequence-of-events data for industrial process monitoring applications where accurate event timing and system diagnostics are essential.
Originally supplied under the ABB Bailey automation platform, the module supports high-reliability event recording functions in process industries including power generation, oil & gas, chemical processing, and manufacturing automation.
The INSEM01 has been officially replaced by the newer INSEM11 model, offering continued support for legacy system migration and maintenance strategies.
