New control systems at KSTAR compatible with ITER standard technologies

Abstract

Through the lessons learned during the ITER control, data access and communication (CODAC) tasks and the interaction with various domestic and overseas communities, the KSTAR control system is being improved with new functions. We have adopted ITER synchronous data bus network (SDN) and time communication network (TCN) to increase the flexibility of control system design and improve system performance. Absolute time-based discharge operations and high-speed data communication interfaces are standardized as KSTAR standard software components. We used the reconfigurable I/O (RIO) library provided by CODAC for the renovation of a fast interlock system, and effectively implemented a real-time core structure through ITER for the next generation real-time control systems. A new hardware platform standard has been adopted for system standardization and convenience of maintenance international collaboration.
