Description
Product Description
The ABB INNPM11 Network Processing Module is a core communication component used within ABB INFI-90 / Symphony distributed control architectures. It functions as a high-speed message processor responsible for data exchange between Controlway, Module Bus, and the INFI-NET network layer.
Designed by ABB for deterministic control environments, this module ensures synchronized information flow between controller-level operations and plant-wide communication infrastructure.
The INNPM11 operates in conjunction with the INNIS01 interface module to establish a complete communication pathway between process control units and the INFI-NET backbone. It manages cyclic data, exception reporting, system polling, and time synchronization across distributed nodes.
