Product Overview
The Foxboro FCM100Et P0926GS Communication Module is an industrial communication component designed to support data exchange within Foxboro Distributed Control Systems (DCS) and industrial automation architectures. Communication modules such as the FCM100Et provide an important connection between control-system components, allowing process data, diagnostic information, configuration information, and system status to move between different parts of the automation network.
In a distributed control environment, reliable communication is essential because controllers, I/O subsystems, operator stations, engineering workstations, and network devices must continuously exchange information. The FCM100Et is designed to operate within this type of architecture, helping connect control-level equipment with the applicable industrial communication infrastructure.
The module is particularly useful where a DCS requires a dedicated communication interface rather than relying solely on the processing capabilities of the main control processor. By separating communication functions from control execution, the overall architecture can be organized into clearly defined control, I/O, and network layers.
The supplied physical dimensions of the Foxboro FCM100Et P0926GS are 114 × 45 × 104 mm, with an approximate weight of 0.284 kg. Its compact form factor allows it to be installed within industrial control equipment and communication assemblies where cabinet space must be used efficiently.

Function and Working Principle
The primary function of the Foxboro FCM100Et P0926GS is to provide a communication interface between components within an industrial control architecture.
A DCS contains many different equipment types. Controllers process control strategies, I/O modules handle field signals, operator stations display process information, and engineering workstations are used for system configuration.
All of these components require reliable communication.
A simplified architecture can be represented as:

Industrial Control Network
↓
FCM100Et Communication Module
↓
Control Processor / I/O System
↓
Field Devices
The communication module helps organize the exchange of information between these system layers.
Depending on the system configuration, communication traffic may include:
- Process data
- Control-system status
- Diagnostic information
- Configuration information
- I/O-related information
- System alarms
- Device status
- Network communication
The module therefore acts as an important communication interface rather than performing the main process-control calculations itself.
What Is the Foxboro FCM100Et Used For?
The FCM100Et is used to provide communication capability within a Foxboro industrial control system.
Its applications can include communication between:
- Control processors
- I/O subsystems
- DCS communication networks
- Engineering workstations
- Operator stations
- Industrial network equipment
- Other compatible control-system modules
In a process plant, the communication module can help transfer information between distributed system components so that operators can monitor the process and control applications can receive the required process information.
This is particularly important in large installations where control equipment may be distributed across multiple cabinets or plant areas.
Role in Industrial Control Systems
Communication is one of the fundamental layers of a modern DCS.

Operator and Engineering Systems
The FCM100Et can therefore contribute to the communication path between field-level data and higher-level control and monitoring functions.
A reliable communication architecture allows:
- Controllers to receive process measurements
- Operator stations to display current values
- Engineering stations to communicate with control equipment
- Diagnostic information to reach maintenance personnel
- System status to be monitored
- Process data to be transferred to higher-level applications
Without reliable communication, even correctly functioning controllers and I/O modules cannot operate as an integrated automation system.
Communication Architecture
The FCM100Et should be considered as part of a complete communication architecture rather than as an isolated component.
A typical structure may include several levels.
Field Level
Sensors and actuators interact directly with the physical process.
I/O Level
Input and output modules convert field signals into information that can be processed by the control system.
Control Level
Control processors execute configured strategies and determine the required control actions.
Communication Level
Communication modules and network equipment provide the data paths between different system components.
Supervisory Level
Operator stations, engineering workstations, servers, and historian systems provide monitoring, configuration, and data-management functions.
The FCM100Et can contribute to the communication layer that links these different levels.
Industrial Applications
The Foxboro FCM100Et can be used in industrial environments where distributed control and reliable system communication are required.
Typical industries include:
Oil and Gas
Communication between control processors, remote I/O systems, operator stations, and process equipment is essential in oil and gas facilities.
Petrochemical
Large petrochemical plants require distributed communication architectures to coordinate multiple process units.
Chemical Processing
Communication modules can support data exchange between control and I/O equipment throughout chemical production facilities.
Power Generation
Power plants depend on reliable communication for process monitoring, equipment control, alarms, and system diagnostics.
Water Treatment
Water treatment facilities can use DCS communication infrastructure to coordinate pumps, valves, treatment systems, and monitoring equipment.
Manufacturing
Industrial manufacturing facilities can use distributed communication architectures to connect control equipment across production areas.
