GE HE700GEN200C Dual-Port Ethernet Module – High-Availability Communication for Series 90-70 PLC Systems

Description

The GE HE700GEN200C is an advanced dual-port Ethernet communication module designed by GE Intelligent Platforms (formerly GE Fanuc) for the Series 90-70 programmable logic controller (PLC) family. As a direct evolution of the single-port HE700GEN100C, the GE HE700GEN200C provides two independent 10/100 Mbps Ethernet interfaces—enabling network redundancy, traffic segmentation, or simultaneous connection to multiple supervisory systems such as HMI, SCADA, historian, and engineering workstations.

Engineered for high-availability industrial environments, the GE HE700GEN200C supports critical protocols including Ethernet/IP, Modbus TCP, and GE’s native SRTP (Service Request Transfer Protocol). This allows seamless integration with Rockwell Automation ecosystems, third-party HMIs, and enterprise data platforms without requiring external protocol converters. Each port can be configured independently, making it possible to isolate control traffic from engineering access—a key requirement for IEC 62443 cybersecurity compliance in regulated industries.

Plugging directly into the Series 90-70 backplane, the GE HE700GEN200C draws power from the rack and requires no external wiring beyond standard Ethernet cabling. Its embedded web server enables browser-based diagnostics, configuration, and firmware updates, significantly reducing dependency on proprietary software during maintenance. For plants operating decades-old Series 90-70 systems, the GE HE700GEN200C delivers a cost-effective path to digitalization, enabling remote monitoring, predictive analytics, and cloud connectivity while preserving validated control logic.

Main Features and Advantages

Dual independent Ethernet ports for resilience and flexibility:
The GE HE700GEN200C’s two isolated ports allow one connection to a plant-floor HMI/SCADA system and another to an engineering workstation or corporate network—eliminating bandwidth contention and improving security. In redundant network architectures (e.g., ring topologies using managed switches), both ports can participate in failover protocols, ensuring continuous communication even during cable or switch failures.

Simultaneous multi-protocol support:
Unlike many legacy gateways that require mode selection, the GE HE700GEN200C runs Ethernet/IP, Modbus TCP, and SRTP concurrently. This enables a single Series 90-70 CPU to serve data to a Rockwell FactoryTalk View HMI via Ethernet/IP while also feeding real-time tags to a Modbus-based historian like OSIsoft PI—maximizing data reuse without additional hardware.

Embedded web interface for rapid troubleshooting:
Accessible via any modern browser, the built-in web server displays IP settings, active connections, error counters, and module status. Engineers can verify tag mappings, restart services, or download logs without installing Proficy software—critical for remote sites with limited IT support.

Designed for brownfield modernization:
With minimal installation effort (no rewiring, no external power), the GE HE700GEN200C transforms isolated Series 90-70 systems into connected edge devices. This extends asset life in capital-intensive facilities while meeting modern requirements for remote access, audit trails, and cybersecurity zoning.

Application Field

The GE HE700GEN200C is widely used in industries where Series 90-70 PLCs remain the backbone of critical processes but require integration with modern IT/OT infrastructure:

• Power Generation: Connects turbine control panels to centralized DCS or NERC CIP-compliant monitoring networks, with one port for operations and another for secure engineering access.
• Water/Wastewater: Enables dual-path communication in SCADA systems—primary link to the control center, secondary to local HMI or backup radio network.
• Oil & Gas: Used in pipeline pump stations to simultaneously report flow/pressure data via Modbus TCP to a regional RTU while allowing field technicians to troubleshoot via Ethernet/IP using a tablet.
• Manufacturing: Integrates legacy bottling or extrusion lines into OEE dashboards by streaming production counts and alarm history to cloud platforms, all while maintaining deterministic control over Genius I/O.

Its dual-port architecture also supports network segmentation per Purdue Model Level 2/3 boundaries, making the GE HE700GEN200C a strategic component in industrial cybersecurity upgrades for aging automation systems.
