I. Product Description
Brand: Foxboro (formerly Invensys, now Schneider EcoStruxure Foxboro I/A Series DCS)
Full model: FBM230
Material part number: P0926GU
Official full name: FDSI Field Device System Integrator Module (Field Device System Integrator)
System compatibility: I/A Series / Foxboro Evo DCS, equipped with FCP270/ZCP270 controllers and FBM chassis baseplate
Matching terminal baseplate TA: Special 4 serial port terminal board, each channel is independently configured by software and does not interfere with each other
Core Hardware Channels (4 Independent Programmable Serial Ports)
4 physical serial ports, each channel is independently configured by software and does not interfere with each other ：
Interface type: Select one from RS-232, RS-422, and RS-485.
Communication rate: Up to 115.2 kbps.
Bus mounting capacity:
RS485 multi-node: Up to 64 slave devices per single port
RS232/422: Direct connection of 1 device per single port
Electrical isolation: Full isolation between channels, between channels and the backplane, resistant to strong electromagnetic interference from power plants and chemical industries
Support for communication protocols and interface devices
Built-in downloadable protocol driver library, enabling mainstream industrial serial port devices to connect to DCS:
Modbus RTU (most commonly used: PLC, frequency converters, MCC motor control cabinets, online analyzers)
Serial data acquisition for flowmeters, chromatographs, water quality analyzers, flame detectors
Data exchange between third-party PLCs (Siemens, AB, GE)
Old-fashioned recorders, weighing instruments, fire and gas FGS controllers
Up to 2000 DCI data points can be sent to the control system database
Electrical and environmental parameters
Power supply: 24VDC (10-30VDC wide voltage range), total power consumption ≤ 2W
Temperature: Working range -40°C to +70°C, suitable for G3 harsh industrial environment enclosures
Protection: IP20, standard FBM rack card type, supports hot swapping and online replacement
Size and weight: Approximately 120×75×40mm, net weight 0.45kg
Backplane bus: 2Mbps FBM fieldbus, for high-speed interaction with the controller
Key functional features
Flexible multi-serial port networking: 4 serial ports running different protocols / different interfaces simultaneously, reducing the number of gateways
Complete self-diagnosis: Module operation indicator lights T0-T4, system alarms for communication disconnection, verification errors, port failures
Redundancy support: Dual-module redundant deployment within the rack to ensure uninterrupted communication for critical analyzers and auxiliary control of the unit
On-site / cabinet dual use: Can be installed in a cabinet or arranged nearby in a explosion-proof cabinet for on-site use
Mass point mapping: Batch conversion of third-party device registers into internal blocks (AI/DI/computation blocks) in the DCS
Typical application scenarios
Petrochemical / Chemical: Serial port data access for online chromatographs, water quality analyzers, mass flowmeters to I/A DCS
Thermal power / Gas turbines: Modbus collection for MCC motor cabinets, vibration monitors, smoke gas analyzers
Oil and gas stations: Third-party PLCs, flow computers, fire and gas systems FGS connection
Factory renovation: Unified connection of old serial instruments to Foxboro I/A system, no need for additional upper computer gateway
