We adopted EtherCAT having a master/slave topology as a network based fieldbus. Since a cyclic data transfer time is less than 1msec, EtherCAT can be provided enough performance for a fast control and a feedback system. Synchronization between slaves can be realized easily by the distributed clock technology. Controllers and sensors are set near equipment, and input and output data to/from a master via an Ethernet cable. It reduces the number of wires and the working time for wiring. In 2016, we installed EtherCAT into three types of equipment control systems. One was a prototype digital LLRF system in the high power rf test stand at SPring-8. Another was sub-encoder readout for an undulator at SPring-8. The other was a control system for a kicker magnet power supply at SACLA. An XMC typed EtherCAT Master module was implemented into each of these systems and connected to multi vendor slaves. In this paper, we report the status of new control system using the EtherCAT technology and future plan.
