Sumario:The supervisory layer of the Large Hadron Collider (LHC) experiments is based on the Prozeßvisualisierungs- und Steuerungsystem (PVSS) [1] and the Joint COntrols Project (JCOP) Framework (FW) [2]. This controls framework includes a Finite State Machine (FSM) toolkit, which allows to operate the control systems according to a well-defined set of states and commands. During the FSM transitions of the detectors, it is required to re-configure parts of the control systems. All configuration parameters of the devices integrated into the control system are stored in the so-called configuration database. In this paper the JCOP FW FSM-Configuration database tool is presented. This tool ensures the availability of all required configuration data, for a given type of run of the experiment, in the PVSS sub-detector control applications. The chosen implementation strategy is discussed in the paper. The approach enables the standalone operation of different partitions of the detectors simultaneously while ensuring independent data handling.
