Description

1. Product Title

Foxboro P0926GS (FCM100ET) – I/A Series DCS Field Control Ethernet Bus Communication Module

2. Product Overview

The Foxboro P0926GS is officially designated as FCM100ET, a core fieldbus communication module for the Foxboro I/A Series distributed control system (DCS), originally under Invensys (now Schneider Electric). It acts as the bridge between the DCS controller backplane and field device Ethernet network, responsible for data forwarding between FCP field control processors, remote FBM I/O modules, HART smart transmitters and upper monitoring workstations. Belonging to the P0926xx serial communication family (including GS/GH/GU/GW/GX suffix variants), P0926GS adopts a rugged aluminum heat-dissipating housing with full PCB conformal coating. It supports redundant network topology to avoid single-point communication failure, provides comprehensive LED diagnostic indicators for link status, bus fault and power abnormality, and ensures stable high-speed data transmission in high-temperature, dusty and electromagnetic interference-intensive process plant environments. It is widely deployed to expand the network capacity of Foxboro legacy I/A DCS racks and realize decentralized field I/O data collection.
