Working Principle After power‑on, module executes hardware self‑check and communication initialization. It receives process data from InfiNet coaxial loop, completes protocol conversion, and transmits data to external host system via Ethernet port. It also forwards downlink command from upper system to DCS control loop.
Installation Requirements Insert module into designated DCS rack slot and tighten locking screw. Connect 24 V DC auxiliary power supply. Complete InfiNet coaxial cable and Ethernet cable wiring strictly according to engineering specification.
Usage Notes Adopt anti‑static protection during handling. Follow system operation manual for hot‑swap execution.
