3. Answers to DCS questionsDetector: T0 • FSM1 - T0 detector hierarchy consists of: detector,T0C and T0A modules, channels. The type of hierarchy is “HV oriented” • FSM2 -It will be useful to have soft-interlock between HV/LV and the LV/HV • FSM3 -alarm for Error states in the FSM for HV and LV system • FSM4 -HV state diagram fulfill our needs
