	NA62 is a fixed target experiment to measure very rare decays of Kaons at CERN Super Proton Synchrotron accelerator. The NA62 experiment line comprises several large detectors installed inside a vacuum vessel with a length of 250 m and an internal diameter of up to 2.8 m. The vacuum installation consists of 170 remote controlled pumps, valves and gauges. The operational specifications of NA62 require a complex vacuum control system: tight interaction between vacuum controllers and detector controllers, including pumping or venting vetoes, and detector start-stop interlocks; most of the valves are interlocked, including the large vacuum sector gate valves; the vacuum devices are driven by 20 logic processes. The vacuum control system is based on commercial Programmable Logical Controllers (Siemens PLC: S7-300 series) and a Supervisory Control And Data Acquisition application (Siemens SCADA: WINCC OA). The control software is built upon the standard framework used in CERN accelerators vacuum, with some specific developments. We describe the controls architecture, and report on the particular requirements and the solutions implemented.

MOPGF103	The Upgrade of Control Hardware of the CERN NA62 Beam Vacuum	318

	NA62 is the follow-up of the NA48 experiment, in the SPS North Area of CERN, and reuses a large fraction of its detectors and beam line equipment. Still, there are many new vacuum devices in the beam line (including pumps, valves & gauges), which required a thorough modification of the control system and a large number of new controllers, many of which were custom-made. The NA62 vacuum control system is based on the use of PLCs (Programmable Logic Controllers) and SCADA (Supervisory Control and Data Acquisition). The controllers and signal conditioning electronics are accessed from the PLC via a field bus (Profibus); optical fibre is used between surface racks and the underground gallery. The control hardware was completely commissioned during 2014. The nominal pressure levels were attained in all sectors of the experiment. The remote control of all devices and the interlocks were successfully tested. This paper summarizes the architecture of the vacuum control system of NA62, the types of instruments to control, the communication networks, the hardware alarms and the supervisory interface.

For two years (Spring 2013 - Spring 2015), the LHC went through its first long shutdown (LS1). It was mainly motivated by the consolidation of magnet interconnects, to allow operation with 6.5 TeV proton beams. Moreover, around the accelerator complex, many other systems were repaired, consolidated or upgraded, and several new installations came to life. The standardization of vacuum controls has progressed in the injectors, with the renovation of most of their obsolete equipment.
