Communication and Protocol Capabilities
Mainstream Ethernet Protocols: SRTP, Modbus TCP, EGD, OPC UA server, PROFINET controller (supports CPU hot backup redundancy), DNP3, can be connected to upper computers, SCADA, servo, instrument equipment;
Serial Port Protocols: Modbus RTU, SNP, ASCII, directly connect to old serial sensors, frequency converters;
Topology flexibly supports star, linear, and ring networking, suitable for long-distance factory distributed control.

Key Functional Highlights
Power-off Protection Energy Storage Unit: In case of sudden power loss, relying on the built-in energy storage unit, the engineering parameters are completely written to the non-volatile flash memory to avoid program loss, no need for additional spare battery maintenance;
Hardware and software redundancy supports dual CPU hot backup architecture, network interfaces can form ring network link redundancy, significantly reducing downtime risks;
Downward compatibility with old equipment allows for mixed mounting of RX3i and Series90-30 modules, upgrading old production lines does not require overall replacement of the rack;
High-speed computing performance is more than 2 times higher than the IC695CPK320 series, suitable for complex logic, batch data collection, and simple motion linkage scenarios;
Programming is compatible with the Unity Pro platform for development, programs can be cross-transplanted across GE’s multiple hardware, low modification cost.

Typical Application Scenarios
Energy and Power: Power plant auxiliary equipment DCS monitoring, wind turbine pitch control, pump station cluster scheduling;
Manufacturing Automation: Large packaging production lines, logistics sorting lines, glass tempering furnace entire line control;
Process Industry: Chemical workshop interlocks, water treatment multi-site distributed control;
Old production line upgrade: Expanding and upgrading the 90-30 system, reusing existing I/O modules to reduce costs.
