Description

Product Overview

The INNPM01 (NPM) is the core network processor for ABB Bailey INFI 90 and Harmony Symphony PCU cabinets. It bridges the local Controlway (CEX bus) inside the rack and the INFI‑NET plant‑wide fiber loop, routing process values, alarms, commands and database traffic between MFPs, I/O modules, operator stations and other PCUs. It maintains the PCU database, schedules deterministic network traffic, and supports primary/backup redundant pairing for high availability. It works together with INNIS01 / INNIS11 INFI‑NET interface modules. It is widely stocked as legacy spare for power, petrochemical, pulp & paper and chemical plants.
