Interface & Communication Layout
Rear edge connector connects DPU backplane for internal bus communicationFront RJ45 socket links to industrial switch via network cableFront panel LEDs: RUN, LINK, ACT status indicators
Core Functions
Transmit real-time process data from DPU to upper monitoring system over EthernetReceive remote setpoints & control commands and forward to Ovation controllerBuilt-in self-diagnosis for link loss, communication timeout; fault info uploaded to system alarm logIP 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 EMIAssign unique IP to each card to avoid IP conflict; check connector tightness periodically during routine maintenance
