  The de­tec­tor con­trol sys­tem for the NA62 ex­per­i­ment at CERN, to be ready for physics da­ta-tak­ing in 2014, is going to be built based on con­trol tech­nolo­gies rec­om­mend­ed by the CERN En­gi­neer­ing group. A rich port­fo­lio of the tech­nolo­gies is planned to be show­cased and de­ployed in the final ap­pli­ca­tion, and syn­er­gy be­tween them is need­ed. In par­tic­u­lar two ap­proach­es to build­ing con­trols ap­pli­ca­tion need to play in har­mo­ny: the use of the high-lev­el ap­pli­ca­tion frame­work called UNI­COS, and a bot­tom-up ap­proach of de­vel­op­ment based on the com­po­nents of the JCOP Frame­work. The aim of com­bin­ing the fea­tures pro­vid­ed by the two frame­works is to avoid du­pli­ca­tion of func­tion­al­i­ty and min­i­mize the main­te­nance and de­vel­op­ment ef­fort for fu­ture con­trols ap­pli­ca­tions. In the paper the re­sult of the in­te­gra­tion ef­forts ob­tained so far are pre­sent­ed; name­ly the con­trol ap­pli­ca­tions de­vel­oped for beam-test­ing of NA62 de­tec­tor pro­to­types. Even though the de­liv­ered ap­pli­ca­tions are sim­ple, sig­nif­i­cant con­cep­tu­al and de­vel­op­ment work was re­quired to bring about the smooth in­ter-play be­tween the two frame­works, while as­sur­ing the pos­si­bil­i­ty of un­leash­ing their full power. A dis­cus­sion of cur­rent open is­sues is pre­sent­ed, in­clud­ing the vi­a­bil­i­ty of the ap­proach for larg­er-scale ap­pli­ca­tions of high com­plex­i­ty, such as the com­plete de­tec­tor con­trol sys­tem for the NA62 de­tec­tor.

  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.

  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.
