KSTAR achieved H-mode operation for 70 seconds in 2016. In this case, it is necessary to have precise and fast operation protection device to protect Plasma Facing Component from high energy and long pulse plasma. The higher the energy of the plasma, the faster the protection device is needed, and the accurate protection logic must be realized through the high-speed operation using signals from various devices. To meet these requirements, KSTAR implemented the Fast Interlock System using Compact RIO. Implementation of protection logic is performed in FPGA, so it can process fast and various input and output. The EPICS IOC performs communication with peripheral devices, CRIO control, and DAQ. The hard-wired signal for high-speed operation from peripheral devices is directly connected to the CRIO. In this paper, we describe the detailed implementation of the FIS and the results of the fast interlock operation in the actual KSTAR operation, as well as future plans.
