The ABB Bailey IMMFP11 is a Multifunction Processor Module used in the INFI 90 / Symphony distributed control system (DCS). It is designed to execute advanced control strategies for industrial processes such as loop control, sequential logic, batch processing, and data acquisition.
As one of the core processing modules in ABB’s legacy Bailey architecture, IMMFP11 acts as the “brain” of the control rack—coordinating I/O modules, executing control logic, and ensuring stable real-time process automation in mission-critical environments like power plants and heavy industry.
