FOXBORO P0926GV FBM231 Field Equipment System Integration Module

Product Overview

FOXBORO P0926GV FBM231 is a redundant field device system integration (FDSI) module in the Foxboro brand I/A Series series under Schneider Electric. Its core function is to integrate dual port field I/O devices with EcoStruxure ™  Foxboro ™ Provide serial communication interfaces between distributed control systems (DCS) to achieve efficient integration and interaction between on-site device data and control systems. This module adopts a redundant design architecture, usually deployed in a configuration of one pair (main module+tracking module), which can achieve module level redundant backup and ensure the continuity of industrial control links. It is equipped with four software configurable serial ports, supports multiple serial communication standards, and is suitable for various scenarios such as direct connection of dual port devices, modem connection, and RS-485 multi station connection. It also has G3 level adaptability to harsh environments and can be directly installed on site. It is a key integrated component in industrial automation systems that connects dispersed field devices and control centers.

Performance characteristics

Redundancy backup guarantee: Supports module level redundancy configuration, with a pair of FBM231 modules working together as the main module and tracking module. The I/O driver can detect heartbeat signals in real time, automatically switch roles in case of failure, or manually switch through SMDH to ensure uninterrupted communication links;

Flexible port configuration: Four serial ports can be independently configured with software communication standards (RS-232/RS-422/RS-485), and 1-4 ports can be configured as a single logical port with redundant cables to achieve stable docking with dual port I/O devices and adapt to diverse field device connection requirements;

Wide device compatibility: Supports modem connection (with RS-232 interface), RS-485 multi station connection, and direct connection of dual port devices, and can be connected to intrinsically safe devices (deployed between terminal components and field devices); Support multiple protocols through downloadable drivers and adapt to different brands of third-party on-site devices;

Efficient data integration: The data from scattered field devices can be centralized and integrated into the Foxboro DCS control database, achieving a complete closed-loop process of on-site device status monitoring, data acquisition, and control instruction issuance. A maximum of 2000 DCI block connections can meet the requirements of large-scale device integration;

Adaptation to harsh environments: With G3 level adaptability to harsh environments, it can be installed directly on site without the need for additional protective enclosures, and is suitable for harsh operating conditions in complex industrial scenarios such as petrochemicals and metallurgy;

Easy installation and maintenance: equipped with clear port identification and terminal component wiring guide, driver download and parameter configuration are completed through DCS system software, without on-site programming; The DIP switch and terminal design of terminal components simplify the wiring and debugging process, making it easier for later maintenance.

Working principle

The core working logic of FOXBORO P0926GV FBM231 module is to achieve serial communication and data integration of "field equipment module DCS system". Under redundant configuration, the main module and tracking module establish a bidirectional communication link with the dual port field devices through terminal components (TA): the main module is responsible for receiving input data from the field devices and uploading it to the DCS control station, while the main and tracking modules simultaneously write output data to the field devices based on I/O drive instructions; The I/O driver monitors the running status of the main module in real-time (such as heartbeat signals). When a fault is detected in the main module, it automatically switches to the tracking module to take over the work, ensuring uninterrupted data transmission. When a single module is working, the field equipment is connected to the module through a serial port, and the port matches the corresponding communication standard (RS-232/RS-422/RS-485) according to the preset configuration. The module parses the field equipment protocol through a downloaded dedicated driver, converts analog or digital signals into data formats recognizable by the DCS system, and converts DCS control instructions into signals executable by the field equipment; The bus terminal resistance of the terminal component can optimize the quality of signal transmission, while DIP switches are used to precisely configure the signal mapping of the RS-232 interface (such as clearing the association between sending and request sending), ensuring communication stability.
