The ABB INNPM22 is a high-performance Network Processor Module (NPM) designed as the primary communication backbone for ABB Symphony Plus and System 800xA distributed control systems. It acts as the intelligent interface between the controller's local bus and the high-speed Infinet (Infi-Net) communication loop. The INNPM22 is engineered to manage high-speed data exchange, handle complex protocol translations (including TCP/IP and Modbus TCP), and maintain network redundancy. By offloading communication tasks from the main processor, it ensures maximum system availability and secure data flow across the plant network. This module features onboard battery backup for volatile memory protection, ensuring critical configuration data is retained during power interruptions.
