9. Enrique Blanco [CERN EN/ICE PLC] The input to the UNICOS application: SPECS (xls file)  The specs XLS file is created either by hand (recurrent intervention of the instrumentation, control and operation engineers) or automatically.  The automatic creation is done via a dedicated application VBA querying several databases (e.g. LHC Layout)  Some of the parameters needed to generate automatically the full code of the PLC are stored locally  Far from being optimal. Action in progress. 9

10. Enrique Blanco [CERN EN/ICE PLC] UNICOS application creation Instances From XLS specs (both to PLC and SCADA) using the Standard UNICOS generators : Schneider and Siemens PLC Logic Completing by hand or automatically by the templates creation in the generator. Those templates are done using the logic parameters included in the XLS specs Also there are predefined parameterized PLC functions. SCADA panels Classic panels created & edited by control engineers or/and by operators Static base panels configured via the window tree and initialized with addSymbol PVSS functionalities. Configuration comes from the LHC Layout data base. SCADA customization unCryo package: - Libraries & scripts (user access, dedicated calculations,…) - Panels (e.g. customized beep, multiple commands (PIDs),…) - Access Control mechanisms (architecture dependent) - SOFT & CMW Front-ends: dedicated calculations & external communications WindowTree & Trend tree generated automatically and imported in HMI Unicos HMI customization by XML configuration (using standard UNICOS mechanisms) 10

13. Enrique Blanco [CERN EN/ICE PLC] UNICOS application update Settings (e.g. deadbands, archiving, …) Online modification and modify to specs whenever possible Devices Spares creation allows online modification. Changes are reported back to the original specs. SCADA: online change of the device PLC: online change of the device and in logic (if needed) store the new version in PARADis (versioning mechanism) Specs update (may need Database updates) Reverse engineering Recreate current settings in the application (PLC * + SCADA) in the XLS specs + generator. 13 * Only available for PLCs Schneider
