FOBORO

Product Classification: 32-Bit RISC Control Processor Product Introduction: The Foxboro FBM219 is the primary control processor module serving as the central computing engine within the Foxboro I/A Series Distributed Control System (DCS). It executes all control strategies, sequential logic, arithmetic computations, and data management tasks for the entire control system. This module is the brain of the I/A Series architecture and interfaces directly with all I/O modules, communication modules, and operator stations.

Product Series: I/A Series Foundation Fieldbus Module Product Introduction: The FBM230 is a dual-port serial communication interface module for the Foxboro I/A Series DCS. It provides RS-232 and RS-485 communication capabilities, enabling the controller to interface with legacy devices, RTUs, PLCs, and other serial devices using Modbus RTU/ASCII protocols.

Product Introduction:​ The FBM232 is a DCS node component for Foxboro Evoluton / I/A Series that provides a 10/100 Mbps Ethernet port to communicate with intelligent field devices or third-party systems using Modbus TCP/IP, EtherNet/IP, or custom drivers. It offloads protocol handling from the control processor.
