Abstract The JT-60 operations were stopped in 2008 in order to be upgraded to a superconducting tokamak device, JT-60 Super Advanced (JT-60SA). The design activity of JT-60SA is going on under the ITER-BA project, and the discussion on the operational scenarios of JT-60SA has begun. On the basis of these situations, we have been on a developmental work for JT-60SA control system. The JT-60 real time control system is composed of a workstation and a VME-based real time controller using a VxWorks. The VxWorks is one of the most commonly used real-time OSs in the embedded system markets. However, the introduction cost is higher than that of other RTOSs. From a cost-effectiveness and a long-term stable supply viewpoint, we have chosen INtime running on Windows OS-based Personal Computer. INtime is able to add a real-time performance to a PC on which Windows is installed. Therefore, in JT-60 real time control system, some of the subsystems running on VxWorks have been replaced with a PC-based control system. In future development activity, we plan to adopt the PC-based controller with INtime as the standard of JT-60SA control system. In this report, the developmental status of JT-60SA control system will be described.
