ABB Bailey IMMFP12 Multi-Function Processor Control Module

Description

The ABB IMMFP12 is a high-capacity processing engine designed as the central intelligence unit for the Bailey INFI 90 and Symphony Plus distributed control systems. This multi-function processor is engineered to execute complex control logic, ranging from simple PID loops to sophisticated sequential and batch control strategies. By utilizing a dedicated microprocessor architecture, the IMMFP12 manages all data acquisition from I/O modules via the slave expander bus and communicates with the broader plant loop through network interface modules. It is the primary vehicle for running user-defined functional block programs, providing the computational power necessary for the stable and efficient operation of power plants, refineries, and large-scale manufacturing processes.
