Product Description

Overview

The ABB SPNPM22 is a high-capacity Network Processing Module (NPM) engineered for the Symphony Plus and Harmony (INFI 90) distributed control systems. It functions as the primary communication hub for plant-wide data, efficiently linking controllers, I/O modules, and other networked devices while enabling advanced control and monitoring capabilities.

Technical Specifications

Functional Highlights

• Central Communication Hub: Directs data flow between local controllers and the plant-wide Cnet, enabling seamless network integration.

• Advanced Message Processing: Optimizes traffic by prioritizing exception reporting, sending only updated data to reduce network congestion.

• Database Management: Maintains a local copy of the node database for rapid point data access without overloading the main controller.

• Redundancy Ready: Supports hot-standby operation with a secondary SPNPM22 for full fault-tolerant performance.

• Diagnostic Monitoring: Built-in LED display provides immediate status feedback and error reporting for efficient troubleshooting.

• Time Synchronization: Ensures millisecond-accurate timestamps for all control events and sequence-of-events recording.

Installation & Configuration

The SPNPM22 is configured via S+ Engineering or Composer. For redundant setups, firmware versions must match across modules. Typically installed in the first slots of a network node to manage interface between the control station and the plant network.

Applications

• Plant-wide Ethernet network integration for Bailey INFI-NET systems

• Distributed control optimization across multiple nodes

• Real-time data collection and exception reporting

• Integration with legacy and modern DCS networks

• Industrial facilities requiring high-speed communication and network reliability
