For the vacuum system NI CompactRIO controllers with embedded real-time processors and programmable FPGAs were selected to design the inter-lock system to maintain ultra-high vacuum conditions and protect vacuum devices. The vacuum pressure protection function and component protection logics worked well during the past years of operation. Be-sides, basic function and other applications such as TCP/IP Modbus communication and real time message APIs were developed. The architecture of the vacuum control system is presented in this paper.}, }
