  The power supply system for the magnets of the CERN PS has been recently upgraded to a new system called POPS (POwer for PS). The old mechanical machine has been replaced by a system based on capacitors. The equipment as well as the low level controls have been provided by an external company (CONVERTEAM). The supervision application has been developed at CERN reusing the technologies and tools used for the LHC Accelerator and Experiments (UNICOS and JCOP frameworks, PVSS SCADA tool). The paper describes the full architecture of the control application, and the challenges faced for the integration with an outsourced system. The benefits of reusing the CERN industrial control frameworks and the required adaptations will be discussed. Finally, the initial operational experience will be presented.

  A large number of control systems at CERN are built with the commercial SCADA tool WinCC OA. They cover projects in the experiments, accelerators and infrastructure. An important component is the Oracle archiver used for long term storage of process data (events) and alarms. The archived data provide feedback to the operators and experts about how the system was behaving at particular moment in the past. In addition a subset of these data is used for offline physics analysis. The consistency of the archived data has to be ensured from writing to reading as well as throughout updates of the control systems. The complexity of the archiving subsystem comes from the multiplicity of data types, required performance and other factors such as operating system, environment variables or versions of the different software components, therefore an automatic tester has been implemented to systematically execute test scenarios under different conditions. The tests are based on scripts which are automatically generated from templates. Therefore they can cover a wide range of software contexts. The tester has been fully written in the same software environment as the targeted SCADA system. The current implementation is able to handle over 300 test cases, both for events and alarms. It has enabled to report issues to the provider of WinCC OA. The template mechanism allows sufficient flexibility to adapt the suite of tests to future needs. The developed tools are generic enough to be used to tests other parts of the control systems.
