General Electric IC200BEM104 Ethernet Communication Module

The GE IC200BEM104 is a compact, high-performance Ethernet communication module designed exclusively for GE’s RX3i Series PLC—GE’s flagship platform for mid-to-large-scale industrial control. As a core connectivity component of the RX3i ecosystem, the GE IC200BEM104 solves a critical challenge in modern automation: enabling reliable, high-speed data exchange between the RX3i PLC and industrial networks, including EtherNet/IP and Modbus TCP.

Unlike basic communication modules that support only a single protocol, the GE IC200BEM104 integrates multi-protocol support, making it versatile for mixed-vendor environments. It acts as a “translation hub”: it converts PLC data (e.g., from GE IC200ALG220 analog I/O modules) into network-compatible packets for transmission to HMIs, SCADA systems, or cloud platforms (e.g., GE Predix), and relays control commands from these systems back to the PLC. The GE IC200BEM104 is particularly valued in industries like manufacturing, water treatment, and power utilities, where seamless network integration is essential for real-time monitoring, predictive maintenance, and compliance with Industry 4.0 standards.

Core Advantages and Technical Highlights

Multi-Protocol Support for Mixed-Vendor Flexibility: The GE IC200BEM104 natively supports both EtherNet/IP and Modbus TCP—two of the most widely used industrial protocols—eliminating the need for additional gateway modules. For example, in an automotive assembly line, the GE IC200BEM104 can communicate with a Rockwell ControlLogix PLC (via EtherNet/IP) to synchronize conveyor speeds, while simultaneously sending production data to a Siemens WinCC HMI (via Modbus TCP). This flexibility reduces system complexity and costs by 30% compared to single-protocol modules, as it avoids the need for protocol converters.

Redundant Ethernet Ports for Fault-Tolerant Connectivity: Equipped with two 10/100Base-T Ethernet ports, the GE IC200BEM104 enables redundant network connections—critical for mission-critical applications where network downtime is costly. If the primary Ethernet link fails (e.g., due to a damaged cable), the module automatically switches to the secondary port within <10ms, ensuring uninterrupted data flow. In a water treatment plant’s pump control system, this redundancy ensures the RX3i PLC remains connected to the SCADA system, preventing unplanned shutdowns of critical water purification processes. The auto-MDI/MDI-X feature also simplifies wiring, as no crossover cables are needed—saving installation time for technicians.

Web-Based Configuration and Remote Diagnostics: The GE IC200BEM104 includes a user-friendly web-based management interface, allowing technicians to configure network settings (IP address, protocol priorities) and monitor module health without specialized software. For instance, a maintenance engineer can access the module’s web interface from a remote location to check Ethernet link status, review protocol error logs, or update firmware—eliminating the need for on-site visits. This remote accessibility reduces troubleshooting time by 50% compared to modules that require local configuration via Proficy Machine Edition. Additionally, the CLI supports advanced configuration for IT teams, enabling integration with enterprise network management tools (e.g., Cisco Prime).

Typical Application Scenarios

In a large-scale food and beverage manufacturing plant, the GE IC200BEM104 is installed in an RX3i PLC (IC200CPU002) that controls a bottling line. The module connects the PLC to two key systems: an EtherNet/IP network linking 8 GE IC200ALG220 analog modules (monitoring bottle fill levels and pressure), and a Modbus TCP network transmitting production data to a cloud-based MES (Manufacturing Execution System). The GE IC200BEM104 sends real-time fill level data to the MES, which tracks batch quality and generates compliance reports. If the primary Ethernet link to the MES fails, the module switches to the secondary port, ensuring no data loss—critical for meeting FDA documentation requirements.

In a municipal water treatment plant, the GE IC200BEM104 enables the RX3i PLC to communicate with a SCADA system via EtherNet/IP, providing real-time data on water flow rates, pH levels, and pump statuses. The module also sends diagnostic data (e.g., I/O module faults) to a predictive maintenance platform (GE Predix) via Modbus TCP, allowing engineers to schedule repairs before equipment fails. During a network upgrade, the GE IC200BEM104’s web interface is used to reconfigure IP settings remotely, minimizing downtime for the water treatment process—ensuring continuous supply to 50,000 residents.

Installation Commissioning and Maintenance Instructions

Installation Preparation: Before installing the GE IC200BEM104, confirm compatibility with the RX3i base unit (e.g., IC200CHS017) and CPU (e.g., IC200CPU002). Verify the environment meets specs: 0°C–60°C, 5%–95% RH (non-condensing). Required tools include a torque screwdriver (0.3 N·m for base unit screws), ESD-safe gloves, a laptop with Proficy Machine Edition, and an Ethernet cable. Safety precautions: Power off the RX3i base unit (lockout/tagout) to avoid electrical shock; align the module with the base unit slot guides and press firmly until it clicks—do not force the module (risk of backplane pin damage); connect Ethernet cables to both ports (for redundancy) and label them (e.g., “Primary-Network,” “Secondary-Network”).

Commissioning & Maintenance Suggestions: During commissioning, power on the base unit and verify the GE IC200BEM104’s status LED is green. Access the web-based interface by entering the module’s default IP address (192.168.1.1) in a browser, then configure network settings (static IP, protocol priorities) and map PLC data tags to network variables. Test communication by sending a sample command from the HMI to the PLC (e.g., “start pump”) and confirming the GE IC200BEM104 relays the command. For daily maintenance, check the Ethernet port LEDs (green = link, amber = data) and review protocol error logs via the web interface. Every 6 months, update the module’s firmware via Proficy Machine Edition and test redundant link failover by disconnecting the primary Ethernet cable. If a fault occurs (red status LED), first check network connectivity and reset the module; replace the GE IC200BEM104 with a GE-approved spare if hardware failure is confirmed—third-party modules may not meet RX3i compatibility standards.
