ABB EI813F｜Ethernet Module｜

1. DMA low load high-speed transmission
Built in 32-bit parallel backplane bus+DMA direct memory reading technology, network communication occupies less than 4% of CPU load, will not occupy E3ES excitation main control voltage regulation and unit protection computing resources, ensuring real-time generator grid connection and voltage stabilization control, suitable for high reliability scenarios in power plants.2. Hot swappable online maintenance
Replace the cabinet with live plug and unplug, and replace the entire DCS control logic and excitation regulation program without interruption; After inserting the card, the hardware is automatically recognized and the network configuration is loaded without the need to restart the controller, ensuring uninterrupted operation and maintenance of the power plant.

3. Hardware full chain fault diagnosis
Dual LED status indicator lights on the panel: running and network communication status; Real time monitoring of network cable disconnections, network conflicts, configuration mismatches, and bus faults, with fault codes automatically uploaded to the upper control station for pop-up alarms, quickly locating network issues.

4. Industrial wide temperature anti-interference hardware
Backboard 24VDC power supply, operating temperature -25 ℃~+70 ℃; Full circuit EMC static electricity, surge, and harmonic protection, suitable for harsh working conditions such as strong electromagnetic and frequency converter interference in the excitation cabinet of power plants; Metal shielded RJ45 interface, resistant to industrial cable interference.

5. Support for redundant dual network architecture
Dual EI813F modules can be configured in pairs to build redundant dual networks, with two independent network cables serving as backups for each other. When a single card/network cable is damaged, the network seamlessly switches without interruption, meeting the safety operation standards of the power station.
