  The UNICOS (UNified Industrial Control System) framework, and concretely the CPC package, has been extensively used in the domain of continuous processes (e.g. cryogenics, gas flows,…) and also others specific to the LHC machine as the collimators environmental measurements interlock system. The application of the UNICOS-CPC to other kind of processes: vacuum and the cooling and ventilation cases are depicted here. One of the major challenges was to figure out whether the model and devices created so far were also adapted for other types of processes (e.g Vacuum). To illustrate this challenge two domain use cases will be shown: ISOLDE vacuum control system and the STP18 (cooling & ventilation) control system. Both scenarios will be illustrated emphasizing the adaptability of the UNICOS CPC package to create those applications and highlighting the discovered needed features to include in the future UNICOS CPC package. This paper will also introduce the mechanisms used to optimize the commissioning time, the so-called virtual commissioning. In most of the cases, either the process is not yet accessible or the process is critical and its availability is then reduced, therefore a model of the process is used to offline validate the designed control system.

  The UNICOS (UNified Industrial Control System) framework was created back in 1998, since then a noticeable number of applications in different domains have used this framework to develop process control applications. Furthermore the UNICOS framework has been formalized and their supervision layer has been reused in other kinds of applications (e.g. monitoring or supervisory tasks) where a control layer is not necessarily UNICOS oriented. The process control package has been reformulated as the UNICOS CPC package (Continuous Process Control) and a reengineering process has been followed. These noticeable changes were motivated by many factors as (1) being able to upgrade to the new more performance IT technologies in the automatic code generation, (2) being flexible enough to create new additional device types to cope with other needs (e.g. Vacuum or Cooling and Ventilation applications) without major impact on the framework or the PLC code baselines and (3) enhance the framework with new functionalities (e.g. recipes). This publication addresses the motivation, changes, new functionalities and results obtained. It introduces in an overall view the technologies used and changes followed, emphasizing what has been gained for the developer and the final user. Finally some of the new domains where UNICOS CPC has been used will be illustrated.
