2. European Organization for Nuclear Research Dev. Phases/interactions with customer Deployment Commissioning URD EN-ICE Capture of the functional requirements of the systems for the process & supervision layers Agreement on the needs between provider & customer EN-ICE Validation of the application in the lab Design Code implementation Tests (logic, IO signals, etc…) Packaging App. Generation (Release) EN-ICE Installation of the new application in-situ Loading of PLC application Setup of PVSS application Load of recipes Pass the system to Gas experts PH-DT1 Tests of application before production Hardware connection tests Functional tests Final tuning of thresholds & set points Training of Gas team members Gas Expert (PH-DT1) Provider (EN-ICE)

3. European Organization for Nuclear Research GCS tools for application generation

4. European Organization for Nuclear Research Generation – building (in the lab) steps/strategy Generation of all application configuration files for PVSS and PLC (OLProc and XML Generator) PVSS –Building and Configuration of the application Installation of PVSS components (unicos & gcs) Configuration of components (anomalies, recipes, dip) Configuration of application specific to Exp (PVSS Project setup, SMS, LDAP, ORACLE, etc…) Extract production configuration files and combine with generated ones (users, recipes, dip..)

5. European Organization for Nuclear Research Tests –packaging (in the lab) PLC tests (with a PVSS version) Software logic tests (unit tests) Connection I/O tests (PLC wago with ioscanning, etc..) PVSS integration tests (once app. Has been built) Tests without PLC connection Check components have been configured correctly Link to panels from WT, faceplates (Diag), etc No purple objects, etc…. Tests with PLC connection Mainly address config tests (with recipes/ check for cyan objects, etc…) Packaging of the PVSS application

6. European Organization for Nuclear Research Deployment (in-situ) DS setup (according to EXP infras.) OWS setup (if valid Installation of PVSS project Connection to PLCs Dowload of recipes.

7.

15. European Organization for Nuclear Research GCS objectives -> Provide homogeneous end-user applications What we provide Build turnkey control application Supervision layer Synoptic views and navigation, alarm handling, recipes Process Control layer I/O, FSM ???, interlock, common logic Define and setup the control infrastructure in Exp What we don’t provide Setup of hardware equipments and instrumentation

16. European Organization for Nuclear Research GCS strategies/principles Strategy Gas systems’ architecture based on a generic model Use industrial technologies SCADA, PLC, fieldbuses Use of UNICOS FW and code generators tools Principles Model-oriented design for both Supervision & Process control Automatic generation of input files for the supervision and process layers Tools to automate the PVSS code production ???

17. European Organization for Nuclear Research GCS operational support Types of support cases Bad configuration parameters (archive, deadband, stop of plc, …) Exp Infrastructure problems (remote access, dip data, etc..) Support level First Line (PH-DT1 gas piquet) Second line support based on best effort (EN-ICE) Tools Remedy for any problems or requests Savannah for bug & patch tracking
