Introduction
Main Functions
- High‑speed Ethernet communication processing: As a system network interface unit, it transmits and receives IONet industrial Ethernet data, realizes real‑time data exchange among controllers, I/O modules and HMI, and supports industrial protocols such as Modbus‑TCP.
- Field I/O signal transfer and pre‑processing: It acquires and conditions field analog and discrete signals, performs data filtering and format conversion, forwards data to main CPU, and distributes main‑controller output commands to field I/O units.
- Local control‑logic execution: The on‑board processor can run simple closed‑loop and sequential logic, off‑load calculation burden from main controller and improve system real‑time response performance.
- Hardware self‑diagnosis and fault reporting: It continuously monitors board power supply, communication links and channel status. It identifies communication breakdown and channel abnormality, uploads fault codes to the system for alarm and supports on‑line fault localization.
- Redundancy coordination: Compatible with dual‑redundant architecture, it cooperates with Mark‑VIe redundant controllers to implement communication link switch‑over, ensure non‑interrupted communication for power‑generation units and meet high‑availability requirements.
Applications
This board is critical communication‑control hardware for GE Mark‑VIe gas and steam turbine control systems, widely deployed in combined‑cycle power plants and thermal power stations for turbine‑generator sets.
- Acts as the Ethernet communication hub inside turbine control system, building data links among main controllers, I/O cards and supervisory HMI stations.
- Transmits operating parameters including unit speed, temperature, pressure and valve position.
- Handles data transmission during unit start‑up, load regulation and protection interlock sequences.
- Serves as maintenance replacement spare part for legacy installed units. Faulty boards are replaced to guarantee stable network operation of turbine control systems.
