ABB Bailey INNPM12 Infi-Net Network Processing Module

Description

The ABB INNPM12 is a high-performance network processing unit designed to manage communication within the Bailey INFI 90 and Symphony Plus distributed control system (DCS) architectures. This module serves as the primary intelligence for an Infi-Net node, coordinating the flow of process data, control signals, and diagnostic information between the plant-wide loop and local controller modules. By working in tandem with a Network Interface Slave (NIS) module, the INNPM12 facilitates the sophisticated routing and protocol translation necessary for large-scale industrial networking. It is engineered to maintain deterministic communication timing, ensuring that time-critical process variables are updated across the system without latency, which is vital for the safe and efficient operation of power and process industries.
