A technical scheme had been put forward, the MVB adapter achieved capabilities of process data, message data and user programmability by using UART Emulation technology in the structure of the host system and MVB controller. And the MVB network was built by using the MVB adapters with other MVB devices. The periodic polling table was achieved by rate monotonic, MVB basic communication capabilities were tested on the MVB network platform, which verified the correctness and feasibility of the MVB adapter.The entire size of MVB adapters was standard 3U, which faciliated integration with other network deviees in the industrial control crates.
