Abstract
The control system for the large tokamak JT-60 at JAERI-Naka was completed in 1985. It was originally composed of 16-bit industrial minicomputers and CAMAC systems with 16-bit microcomputers. Rejuvenation of the control system has become necessary to improving the control performance. The renewal of the control system is also stimulated by the requirements for upgrading the software development and hardware maintenance environment of the control system. This paper describes how the control system was and will be upgraded, utilizing the advanced technologies of VME and networks. Two years ago, a VMEbus-based 32-bit multiprocessor system for fast plasma control and a new operator's console using UNIX workstations connected to an Ethernet LAN were developed to cope with upgrading the JT-60 tokamak (JT-60U). VME and network applications are now being extended to the level of subsystem controllers.
