Profinet / EtherNet-IP Deterministic Network and Firmware Compatibility

The GE Multilin F35 uses a modular Universal Relay hardware structure with CPU-based processing, configurable I/O expansion, and communication interfaces. The relay architecture supports high-speed Ethernet communication functions through installed communication modules, enabling deterministic data exchange for protection monitoring, event reporting, and substation automation systems.

The F35 firmware platform provides compatibility management for configured hardware modules, including CT/VT acquisition boards, digital I/O assemblies, and communication interfaces. Module configuration, FlexLogic programming, and firmware revision control define the operational behavior of the protection system.

Frequently Asked Questions

Q: Can the F35 support hot-swap replacement of installed modules?
A: The F35 uses a modular architecture; however, module replacement procedures must follow GE Multilin maintenance requirements. Power isolation and configuration verification are required before removing or installing hardware assemblies.

Q: What is the function of the CT/VT input modules in the F35 configuration?
A: CT/VT modules provide analog current and voltage acquisition for feeder protection elements, metering calculations, fault recording, and protection algorithm execution.

Q: Which communication protocols are available on the F35 relay?
A: The F35 supports Modbus RTU, Modbus TCP/IP, DNP 3.0 serial/TCP communication, and optional IEC 61850 GOOSE and MMS functions depending on installed communication options.

Field Installation Guidelines

• Install the relay in a suitable protection panel with adequate mechanical support and environmental protection.
• Route CT and VT wiring separately from high-energy power conductors to reduce electromagnetic interference.
• Connect CT secondary circuits using correct polarity and approved shorting practices during maintenance activities.
• Apply shielded communication cables where required and terminate shields according to site grounding standards.
• Verify auxiliary supply voltage before energizing the relay. Confirm the installed power supply module matches the system voltage.
• Check terminal tightness, module seating, and rear communication connections before commissioning.
• Perform configuration verification after installation, including CT/VT ratios, digital input assignments, output relay logic, and communication addressing.
