Description

Overview

The ABB INNPM01 is a dedicated network processing unit developed for the INFI-90 and Symphony distributed control platforms. It operates as a central communication handler, coordinating data exchange across controllers, operator interfaces, and distributed subsystems.

By managing message routing and communication timing, this module supports stable and predictable system behavior across complex plant-wide networks. It is commonly deployed in installations where multiple control nodes must exchange data in real time.

Core Functions

• Executes communication processing for system-wide data exchange

• Routes messages between controllers, HMIs, and I/O modules

• Manages proprietary ABB communication protocols

• Provides network diagnostics and error monitoring

• Maintains synchronization across distributed control nodes
