ABB Bailey INNIS11 Infi-Net Network Interface Slave Module

Description

The ABB INNIS11 is a high-speed communication module designed to facilitate the transfer of data between the plant-wide Infi-Net (Cnet) loop and the local Harmony control bus. Serving as the primary interface for distributed control processors, this module manages the buffering and routing of network traffic to ensure that control instructions and process variables are delivered with deterministic precision. It is a critical component for the Symphony Plus and INFI 90 architectures, providing the essential link required for multi-node synchronization and system-wide data transparency. The INNIS11 is engineered for continuous duty in industrial environments, offering high throughput and robust error-checking capabilities to maintain the integrity of the DCS communication backbone.
