Abstract: Aiming at solving the problem of lacking theory for practice and reference for safety DCS platform localization research and development, the hardware and software design of data bus base on MELTACN safety DCS platform were investigated. A method of hardware design which include double circle and optical Switch function design and a method of software design which is full data transmission policy base on RPR protocol were presented. The reliability and real time performance were evaluated on the CPR1000 safety DCS platform, data link robust, response time and response time stability were tested. The results indicate that the hardware and software design of MELTACN safety DCS platform have excellent performance of data link robust, response time and response time stability.

 

Key words: 1E DCS; ring network data bus; bus system; robust of link; stability of response time
