	Tokamak using superconducting magnets is becoming more and more important as long pulse operation and the ability to confine high temperature and density plasma to the interlock system to protect the device. 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.

The Korea Superconducting Tokamak Advanced Research (KSTAR) interlock related systems are configured with various system such as fast interlock, supervisory interlock, plasma control, central control, and heating using various types of hardware, software, and interface platforms. For each system, monitoring and analysis tools are already well-developed. However, for the analysis of system fault behavior, these heterogeneous platforms do not help finding the relation of failure. When the interlock events are latched or pulse is stopped by PCS, events are transmitted to different actuators and it could make another events via various interface. In other words, it could lead another factor of fault causes on different system. Through this application we will figure out sequence of fault factor during the pulse-by-pulse KSTAR operation. The KSTAR Data Integration System (KDIS) is configured with KSTAR event-driven architecture and data processing environment. This application will be developed on the KDIS environment and synchronized with KSTAR event. This paper will present the development of shot fault sequence analysis logic and application with KDIS.
