Description
The ABB PNI800 (Catalog/Product Code: PNI800K01) is a high-performance Plant Network Interface Module designed specifically for ABB’s Symphony Plus control system architecture.
Operating as a critical bridge component, the PNI800 facilitates bi-directional, real-time communications between engineering stations, HMI/SCADA workstations (such as S+ Operations or 800xA Operations), and SD Series controllers connected across the PN800 real-time control network.

Core Features & Operating Capabilities
- Parallel Redundancy Protocol (PRP) Support: Fully complies with IEC 62439 standards, connecting to dual identical local area networks (PN800A and PN800B) as a Dual Attached Node (DANP) to provide zero switch-over time and eliminate single points of failure.
- Seamless System Integration: Acts as the primary communication gateway required for any PC workstation running S+ Engineering (SPE), Symphony Plus Operations (SPO), 800xA Operations, or Harmony OPC servers to talk directly to SD series controllers.
- Hot-Swappable Design: Supports online module insertion and removal on compatible base units to minimize downtime during system maintenance.
- Robust Diagnostic Logging: Equipped with a front-panel mini-USB diagnostic port and comprehensive internal status indicators to track data throughput, link health, and node status.
