System integration of the ASDEX-upgrade timing system

This paper describes the integration methods applied to incorporate a trigger-timer system into the control system of a tokamak. The described system is a unified means to initiate local actions at each component necessary to create, measure and maintain a plasma. Abstract data representation and model building was used to unify the transmission to the tokamak's components. Lists of a priori scheduled actions as well as online detected events are disseminated by merging them into one stream of high level messages
