{The TRD DCS Project} In order to operate a detector like the ALICE detector a system is needed to control and run the detector. Each sub-detector has its own DCS (Detector Control System). This system takes care of the "health" of the detector. During startup the DCS has to be the instance started first. Without a running DCS the detector is not operable at all. Once the detector is running the DCS checks environmental parameters like temperature and supply voltages. In the case of TRD and TPC the DCS is responsible for the initializing the detector electronics i.e. threashold settings and program download. HV and low voltages are set and controlled. Each of the different running conditions can be identified with different states. Therefore the DCS will be will be implemented in terms of finite state machines using the FSM++ build in the PVSS system.
The soft- and hardware of the DCS is currently under development. According to the different layers of the complete DCS the tasks and groups are collected below:
