Introduction The ultimate goal is a working Detector Control System (DCS) ready for exploitation, allowing to control and operate the experiment during all modes of operation and according to defined requirements. The Control Systems for Tracking chambers detector should be ready to be used during the final assembly and commissioning. The main parties involved in the DCS project are the various detector groups and the groups providing the external services. In addition the ECS and Offline systems as well as the LHC Machine need to be linked-up with DCS. The control and operation of the experiment takes place on the ECS layer. Through this layer DCS is linked up with the Data Acquisition (DAQ), Trigger (TRG) and Offline systems and with the LHC Machine(fig.1).

Fig. 1 Experimental Control System

DCS layout The ‘standard’ DCS model consists of a number of hardware and software components on three hierarchical layers: the supervision layer, the control layer and the field layer. Supervision layer (PVSS2, Framework) The supervision and operation of the detectors take place on this layer and some of the tools and facilities needed are: -SCADA framework tools (PVSS2,Framework) -logging and archiving facilities -alarms -configuration databases -application programs and data -object library for supervision -supervision and operation programs (Finite State Machines)

Control layer On the control layer the collection and processing of data takes place and the following components can typically be found here: - Process Control Units - Local Operator Workplace - Local Engineering Workplace - Data server - Application programs and data - Object library for process control - Local operation programs - Sub-detector configuration data Field layer The connection of the detector equipment to DCS takes place on the field layer via sensors, I/O-interfaces, OPC servers and fieldbuses.

ALICE policy: Our baseline approach is to build the ALICE DCS as a distributed PVSS system Each detector DCS shall be a distributed PVSS system “Central DCS” will connect to all PVSS systems –Distributed system of distributed systems
