27/03/03 M. Gonzalez Berges / JCOP FW team 3 The Joint COntrols Project Set up in 1998 as a collaboration between the four LHC experiments and CERN as equal partners Project mandate: “To develop a common Framework and components for detector control of the LHC experiments and to define the required long-term support.“ JCOP comprises many activities Evaluation of different technologies Main subprojects Framework Detector Safety System (DSS) Gas Systems And others

27/03/03 M. Gonzalez Berges / JCOP FW team 4 The JCOP Framework Project established in May 2000 Use Architecture WG Framework Design Proposal as starting point Aims Reduce the development effort Reuse of components Hide complexity Help in the learning process Facilitate the integration Reduce resources needed afterwards Homogeneous control system Operation Maintenance

27/03/03 M. Gonzalez Berges / JCOP FW team 5 Approach Followed Provide a higher layer of abstraction reduce knowledge of tools interface for non experts Customize & Extend industrial components Modular/Extensible core mix & match components As intuitive as possible Global rather than local optimization Not a complete control system!
