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

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!

Types of Users

Component Developer Extends the Framework

System Developer Develops a controls application using the Framework

System Integrator Puts together systems developed separately

End Users Domain Expert (e.g. gas, high voltage)

Framework Deliverables

Guidelines document Devices Tools Libraries Examples Tutorial & training

27/03/03 M. Gonzalez Berges / JCOP FW team 10

Guidelines and Conventions

Guidelines to produce a coherent control system Look and feel

e.g. colours, fonts, layout Alarm classes Naming convention Exception handling File organization and so on

Devices

Representation of real-world device or logical entity Device consists of

Supervisory Data Point Type(s) Library Panels

Front-end object Commercial Custom made

Tools (I)

Device Editor/Navigator Main interface to the Framework System management: installation, login, etc Configuration and operation of devices

Controls Hierarchy High level view and behaviour of experiment Includes Finite State Machines (based on SMI++) Provides predefined behaviour (partitioning rules)

External Alarm Handler Receive alarms in PVSS from a external system

Trending Simplify & extend PVSS trends Pages of predefined plots, templates, tree

27/03/03 M. Gonzalez Berges / JCOP FW team 14

Tools (II)

Generic External Handler To incorporate C++ code to panels and ctrl manager Easier to use than standard PVSS C++

Mass Configuration Initial release including creation and deletion Manipulation of device sets coming

Summary

Successful collaboration Development process

Framework WG Feedback from users

Deliverables in production Overhead of consultancy and support Useful feedback from users

Recent external JCOP Review Approach adopted was supported Framework identified as one of the key elements of JCOP Good support for common devices Databases an important issue to be followed
