Product Overview

The Foxboro FCP270 and FCP280 are key components of the Foxboro I/A Series distributed control system (DCS), now part of Schneider Electric’s EcoStruxure Foxboro DCS. They function as Field Control Processors (FCPs), essentially serving as the “brains” of the control system at the field level.

Key Functions

Executing Control Logic: The FCPs run the control algorithms and strategies that automate the industrial process.
Managing I/O: They handle the input and output of data to and from field devices (sensors, actuators, etc.) through Fieldbus Modules (FBMs).
Communication: They facilitate communication with other system components, such as operator workstations, historians, and other control processors.

FCP270

Description: The FCP270 is a compact and robust processor designed for a variety of process control applications. It provides a reliable platform for implementing control strategies, acquiring data, and managing alarms.
