Foxboro ™ DCS Field Device Controller 280（FDC280）

The main module on the I/O side is responsible for reading and writing I/O points, while the backup module monitors device connections through "heartbeat commands" and synchronizes I/O values in real-time. When the main module loses connection, the backup module seamlessly takes over without any process fluctuations

2. Maintain convenience

Hot plug support: Replacing the FDC280 module does not require disconnecting the backplane power supply, and does not affect the field I/O signal of another module.

Status visualization: The front of the module includes an LCD display screen (displaying module identification, role, hardware version, network status) and LED indicator lights (running status, Ethernet connection status), supporting the configuration of "letterbug" through panel buttons.

Summary

FDC280 is Schneider Foxboro ™  DCS is a specialized controller designed for the "field equipment integration" scenario, with the core advantages of not requiring FBM to directly interface with multi protocol devices, supporting fault-tolerant redundancy, and adapting to harsh field environments. It is suitable for industries such as chemical, power, oil and gas that require high reliability field control. Its dual core architecture, flexible network configuration, and three-layer fault-tolerant design can effectively reduce the complexity of on-site wiring, improve the integration efficiency and system availability between DCS and on-site devices.
