  The On-Line Isotope Mass Separator (ISOLDE) is a facility dedicated to the production of radioactive ion beams for nuclear and atomic physics. From ISOLDE vacuum sectors to the pressurized gases storage tanks there are up to five stages of pumping for a total of more than one hundred pumps including turbo-molecular, cryo, dry, membrane and oil pumps. The ISOLDE vacuum control system is critical; the volatile radioactive elements present in the exhaust gases and the High and Ultra High Vacuum pressure specifications require a complex control and interlocks system. This paper describes the reengineering of the control system developed using the CERN UNICOS-CPC framework. An additional challenge has been the usage of the UNICOS-CPC in a vacuum domain for the first time. The process automation provides multiple operating modes (Rough pumping, bake-out, high vacuum pumping, regeneration for cryo-pumped sectors, venting, etc). The control system is composed of local controllers driven by PLC (logic, interlocks) and a SCADA application (operation, alarms monitoring and diagnostics).

  The Industrial Controls and Engineering (EN-ICE) group of the Engineering Department at CERN has produced, and is responsible for the operation of around 60 applications, which control critical processes in the domains of cryogenics, quench protections systems, power interlocks for the Large Hadron Collider and other sub-systems of the accelerator complex. These applications require 24/7 operation and a quick reaction to problems. For this reason the EN-ICE is presently developing the monitoring tool to detect, anticipate and inform of possible anomalies in the integrity of the applications. The tool builds on top of Simatic WinCC Open Architecture (formerly PVSS) SCADA and makes usage of the Joint COntrols Project (JCOP) and UNICOS Frameworks developed at CERN. The tool provides centralized monitoring of the different elements integrating the controls systems like Windows and Linux servers, PLCs, applications, etc. Although the primary aim of the tool is to assist the members of the EN-ICE Standby Service, the tool may present different levels of details of the systems depending on the user, which enables experts to diagnose and troubleshoot problems. In this paper, the scope, functionality and architecture of the tool are presented and some initial results on its performance are summarized.
