The FOXBORO P0926GV FBM231 is an important component of the Foxboro Evo Distributed Control System (DCS), specifically the Field Device System Integrator (FDSI) module.

Key Features and Functions:

Field Device System Integrator (FDSI): Its primary role is to act as an interface between field I/O devices, such as sensors, actuators, and other instruments, and the Foxboro Evo control system.

Four Serial Ports: The FBM231 is equipped with four independent serial communication ports.

Configurable Serial Protocols: Each of the four ports can be individually configured in software to support different serial communication standards:
RS-232: for direct connection to a single device or modem.
RS-422: For point-to-point or multipoint connections with better noise immunity over longer distances.
RS-485: for multi-split networks, allowing a single port to communicate with multiple devices (up to 16 devices per port, up to 64 devices per FBM231).

Redundancy: FBM231 modules are designed to operate in redundant pairs. One module acts as the “master” and the other as the “tracker”, ensuring continuous operation even if one of the modules fails. They communicate with dual-port field devices to maintain this redundancy.

Downloadable I/O Drivers: This FBM is a general purpose hardware module. Different software drivers can be dynamically downloaded to configure the FBM to recognize and communicate with a variety of field device protocols; Foxboro provides standard drivers or custom drivers can be developed.

Data Acquisition and Conversion: It collects data from field devices, performs the necessary conversions (e.g., analog-to-digital, scaling), and stores the data in an internal database for use by the Foxboro Evo system’s plant management functions and operator displays. It can also write data to field devices.

Control Block Support: It supports standard Foxboro Evo Distributed Control Interface (DCI) block types for seamless integration into control logic.

Mounting: It is mounted on a modular chassis that can be DIN rail or rack mounted.

Rugged design: A rugged extruded aluminum enclosure provides physical and electrical protection for industrial environments.
