ABB Bailey INNPM22 Network Processing Interface Module

Description

The ABB INNPM22 is a core network processor module designed for the Symphony Plus and INFI 90 distributed control systems. It functions as the primary intelligence for managing communications between the Harmony control unit and the high-speed INFI-Net plant loop. This module is responsible for coordinating data traffic, executing network protocols, and ensuring that process variables are synchronized across the DCS backbone. By offloading communication tasks from the main controller, the INNPM22 maintains system determinism and high-speed data throughput, making it essential for large-scale industrial plants requiring reliable, real-time information exchange between multiple control nodes.
