The CC‑TFB811 is a high-end fieldbus interface / gateway module designed for integration of multiple fieldbus segments into industrial automation systems. It supports multiple bus protocols (such as FOUNDATION Fieldbus H1, HSE, or similar) and offers enhanced throughput, diagnostics, and redundancy options. This module acts as a communication hub, linking controllers and distributed field devices with robust performance.
This gateway is intended for critical process control applications where high availability, fault detection, and scalable connectivity are essential. It fits modular I/O racks or control cabinets and is engineered to operate reliably in harsh industrial environments.

The CC‑TFB811 is a robust fieldbus gateway that bridges control system buses with multiple fieldbus networks. It provides four independent H1 connections to field segments and two high-speed Ethernet uplink ports for redundancy or coupling to the control network.
Internally, the module contains protocol engines, line drivers, redundancy switch logic, diagnostic circuits, and link supervision. It monitors link integrity, device status, error rates, and routing. In the event of link failure, it can switch to backup uplinks or alternate paths seamlessly, ensuring high system availability.
In use, the CC‑TFB811 sits in a modular I/O rack or dedicated fieldbus cabinet. Control signals, configuration data, and diagnostics flow through it between the control system and distributed field instruments, actuators, and sensors. It is suited for large-scale, mission-critical automation systems.
