Design status of ITER IC H&CD plant system control

A functional approach has been used to define functions & responsibility sharing of each Local Control Unit (LCU) and Ion Cyclotron Heating and Current Drive (IC H&CD) Plant System Control (IC-PSC). The resulting functional architecture of the IC H&CD control system is detailed in this paper. The paper highlights functional study of management of fast radio-frequency (RF) arc protection across the IC H&CD subsystems. Lastly, a possible hardware architecture compliant with the functional one is described.
