This paper describes ITER PF converter system architecture in details. According to its real-time and reliability characteristics, ITER PF converter system uses an industrial Ethernet fieldbus based on EtherCAT protocol with high real-time communication performance to develop its remote monitoring system. This system follows ITER design specification, it realize the real-time monitoring of thousands of analog and digital signals, and can realize remote operation of the switches in the field layer, real-time data and historical data query, event alarm and authority management functions. The system has achieved continuous and stable operation on the test platform of ITER PF converter system, meeting the requirements of high real-time performance and reliability of the remote monitoring system of ITER PF converter system.
