As a seasoned expert in industrial automation, I can tell you that the FOXBORO FCM10EF is a truly vital piece of the Foxboro I/A Series (and now Schneider Electric’s Foxboro Evo) distributed control system. It’s not an I/O module in the traditional sense, but rather a Fieldbus Communication Interface Module. Its role is critical for connecting groups of Fieldbus Modules (FBMs) located remotely to the main I/A Series control station, especially over long distances and in electromagnetically noisy environments.
Think of it as a specialized “bridge” that converts signals between different parts of the Foxboro system, specifically enabling fiber optic communication. This is incredibly powerful for expanding your system’s reach and enhancing its robustness.

Detailed Product Description:
As an expert in the world of large-scale industrial automation, I’ve seen firsthand how crucial reliable communication infrastructure is. In a Foxboro I/A Series DCS, you often have I/O modules (FBMs) spread across vast distances within a plant. Running traditional copper cables for miles is often impractical, costly, and highly susceptible to electrical interference. This is precisely the problem the FOXBORO FCM10EF (often identified by its part number P0916CP) solves. It’s a specialized module that enables you to leverage the benefits of fiber optic communication to extend the reach and enhance the robustness of your I/A Series system.
Core Functionality and Fiber Optic Advantage: Extending the DCS Horizon
The primary function of the FCM10EF is to act as a protocol and media converter. It takes the 2 Mbps High-Level Data Link Control (HDLC) signals from the backplane of the FBM baseplates (where your analog and digital I/O modules reside) and converts them into 10 Mbps Ethernet signals that are transmitted over fiber optic cables. This conversion is crucial for several reasons:
- Extended Distance: Fiber optic cabling allows for significantly longer transmission distances compared to traditional copper. The FCM10EF can communicate with a multi-port fiber optic converter (hub) up to 2 kilometers (1.24 miles) away. This is invaluable for geographically dispersed plants, allowing you to centralize your control room while distributing your I/O closer to the field devices.
- Noise Immunity: Fiber optic cables are completely immune to electromagnetic interference (EMI), radio frequency interference (RFI), and lightning strikes. In industrial environments teeming with motors, arc welders, and high-voltage power lines, this immunity is a game-changer. It ensures crystal-clear data transmission without corruption, leading to greater system stability and fewer spurious alarms or control issues.
- Electrical Isolation: Since fiber optic cables transmit light, they provide inherent electrical isolation. This protects your control system from ground loops and voltage differentials that can occur between different parts of a large plant, further enhancing system reliability and safety.
- Network Expansion: The FCM10EF integrates with multiport fiber optic converters (hubs), which then connect to the main I/A Series control station via the high-speed Ethernet trunk Fieldbus. This allows for expanded networking capabilities, enabling you to link multiple groupings of FBMs across a wide area to a single control station. Up to six groupings of FBMs can be linked to each redundant multiport fiber optic converter, supporting a large number of I/O points.
The FCM10EF module design is compact and rugged, typically featuring an extruded aluminum exterior that provides robust physical and electrical protection for its internal circuits. These units are built to withstand the harsh conditions of industrial plants, often meeting environmental suitability standards like ISA Standard S71.04 Class G3. Like other Foxboro FBMs, it’s designed for easy removal and replacement from its baseplate without requiring power shutdown, simplifying maintenance.
For applications requiring continuous uptime, the FCM10EF supports redundancy. A pair of FCM10EF modules can be used in a Master/Tracker configuration for each FBM grouping. If one module experiences a fault, the other seamlessly takes over communication, ensuring uninterrupted data flow and control. This level of redundancy is critical for high-availability systems.
The module receives its power (24 VDC) from the baseplate it’s mounted on. Front panel LEDs typically provide visual status indication for operational health and communication activity, aiding in quick diagnostics.

Applications:
The FOXBORO FCM10EF is invaluable in applications where I/O needs to be widely distributed or where severe electrical interference is a concern:
- Large-Scale Process Plants (Oil & Gas, Chemical, Petrochemical): These plants often span vast geographical areas. The FCM10EF allows for distributing FBMs close to field devices in different units or areas, connecting them all back to a central control room over long fiber optic runs.
- Power Generation Facilities: Power plants contain high-voltage equipment and significant electromagnetic noise. Using FCM10EF ensures reliable communication for critical I/O, such as monitoring boiler performance, turbine status, and generator output from remotely located FBMs.
- Water and Wastewater Treatment Plants: These facilities are often spread out, with pumping stations and treatment units at various locations. The FCM10EF enables efficient data acquisition and control from these distributed points.
- Mining and Metals Industries: In environments with heavy machinery, crushers, and furnaces, electrical noise is prevalent. Fiber optic communication via FCM10EF provides the necessary signal integrity and extends the network to remote parts of the mine or plant.
- Any Application with Distributed I/O or EMI/RFI Challenges: If you need to place your I/O modules far from the control room, or if your plant environment is electrically noisy, the FCM10EF is the ideal solution to ensure robust and reliable communication.
