ABB IMMFP12, infi 90, Multi-Function Processor Module

The Harmony Rack Multifunction Processor (IMMFP11/12) is a multiple loop, analog, sequential, batch and advanced control processor. It provides information processing with advanced data acquisition features and can easily implement complex control strategies. The IMMFP11/12 controllers are fully compatible with the INFI 90® OPEN system in functionality, communications and packaging. The IMMFP12 has twice the memory capacity of the IMMFP11.
Harmony rack controllers receive process I/O from analog and digital I/O modules. The Expander Bus provides the communication link between the MFP and the I/O modules. These controllers communicate on the Controlway with other Harmony rack controllers, including Harmony bridge controller. The rack controllers communicate with other system nodes on the control network (Cnet) via the Harmony rack communication modules.
Multiple control languages are supported in the Harmony rack controllers, including function codes, C, Basic, Batch 90™ , and Ladder.
