Core Functions

Transmit real-time process data from DPU to upper monitoring system over Ethernet
Receive remote setpoints & control commands and forward to Ovation controller
Built-in self-diagnosis for link loss, communication timeout; fault info uploaded to system alarm log
IP address and network parameters configurable online via Ovation configuration software

Application Scenarios

Unit-level DPU networking for boiler/turbine in thermal power plants; Ovation DCS interconnection with plant MES/database; spare replacement for upgraded legacy Ovation systems.

Operation & Maintenance Notes

Deploy shielded CAT5e cable and keep wiring away from high-power cables to reduce EMI
Assign unique IP to each card to avoid IP conflict; check connector tightness periodically during routine maintenance
