The vacuum control system of most of the CERN accelerators is based on Siemens PLCs and on PVSS SCADA. The application software for both PLC and SCADA started to be developed specifically by the vacuum group; with time, it included a growing number of building blocks from the UNICOS framework. After the transition from the LHC commissioning phase to its regular operation, there has been a number of additions and improvements to the vacuum control system, driven by new technical requirements and by feedback from the accelerator operators and vacuum specialists. New functions have been implemented in PLC and SCADA: for the automatic restart of pumping groups, after power failure; for the control of the solenoids, added to reduce e-cloud effects; and for PLC power supply diagnosis. The automatic recognition and integration of mobile slave PLCs has been extended to the quick installation of pumping groups with the electronics kept in radiation-free zones. The ergonomics and navigation of the SCADA application have been enhanced; new tools have been developed for interlock analysis, and for device listing and selection; web pages have been created, summarizing the values and status of the system. The graphical interface for windows clients has been upgraded from ActiveX to QT, and the PVSS servers will soon be moved from Windows to Linux.
