The ABB Bailey IMMPI01 is a Multi-Function Processor Interface Module used in the INFI 90 / Net 90 distributed control system (DCS). It serves as a critical communication bridge between the host computer system and ABB Bailey control modules such as the INICT03A Computer Transfer Module.
In industrial automation architectures, IMMPI01 is responsible for enabling high-speed data exchange, system-level communication, and process monitoring integration. It is widely deployed in power plants, oil & gas facilities, and large-scale process industries, where stable and deterministic data transfer is essential for plant safety and efficiency.
