The CAMAC hardware based timing system has been used to synchronizing pulse discharge sequential events and data collection of the interesting plasma phenomenon of the JT-60 plasma experiments. However, more flexible and intelligent timing system features with more state-of-the-art system is required corresponding to the increase of the requirement to realize more advanced plasma control and to minimize system maintenance cost. The combinations of the VME-bus system with high-speed data communication network by the reflective memory module and user-friendly application software based on MATLAB tools was selected for the new timing system. The new timing system provides the 50$$mu$$sec master clock, various timing signal preparation logic, which is built into DSP module conjunction with discharge sequence event. Except clock pulse generator (CPG) module, no other special hardware-timing module is necessary for the new timing system.
