Working Principle After inserting into DCS rack and powering on, onboard microprocessor initializes network protocol stack. The board receives process data from DCS controller through rack backplane, encapsulates data into network frames and transmits frames to other DCS nodes over control network. It receives data packets sent from other network nodes, decapsulates frames and transfers valid process data to the controller. The board continuously monitors network signal quality and uploads fault information to DCS workstation when communication anomaly appears.
Installation Requirements Power off rack before card insertion if hot swap function is not enabled; Insert card fully into empty rack slot and lock front latch; Connect network communication cable to front panel port; Configure node network address in DCS engineering software after installation; Verify rack backplane power load capacity.
Precautions for Use Take anti-static protection before touching PCB and gold-plated connectors; Do not scratch gold contact surface; Keep network cable connector clean and dry; Back up DCS network configuration file before card replacement; Check LED communication indicators in regular system inspection.
