  CERN’s planned large su­per­con­duct­ing col­lider pro­ject pre­sents sev­eral new chal­lenges to the Con­trol Sys­tem. These are dis­cussed along with cur­rent think­ing as to how they can be met. The high field su­per­con­duct­ing mag­nets are sub­ject to "per­sis­tent cur­rents" which will re­quire real time mea­sure­ments and con­trol using a math­e­mat­i­cal model on a 2-10 sec­ond time in­ter­val. This may be re­alised using di­rect links, mul­ti­plexed using TDM, be­tween the field equip­ment and cen­tral servers. Quench con­trol and avoid­ance will make new de­mands on speed of re­sponse, re­li­a­bil­ity and sur­veil­lance. The in­te­gra­tion of large quan­ti­ties of in­dus­tri­ally con­trolled equip­ment will be im­por­tant. Much of the con­trols will be in com­mon with LEP so a seam­less in­te­gra­tion of LHC and LEP con­trols will be sought. A very large amount of new high-tech equip­ment will have to be tested, as­sem­bled and in­stalled in the LEP tun­nel in a short time. The man­power and cost con­straints will be much tighter than pre­vi­ously. New ap­proaches will have to be found to solve many of these prob­lems, with the ad­di­tional con­straint of in­te­grat­ing them into an ex­ist­ing frame­work.

  Mod­ern in­dus­trial process con­trol sys­tems have de­vel­oped to meet the needs of in­dus­try to in­crease the pro­duc­tion while de­creas­ing the costs. Al­though par­ti­cle ac­cel­er­a­tors de­sign­ers have pi­o­neered in con­trol sys­tems dur­ing the sev­en­ties, it has now be­come pos­si­ble to them to profit of in­dus­trial so­lu­tions in sub­sti­tu­tion of, or in com­ple­ment with the more tra­di­tional home made ones. Adapt­ing and in­te­grat­ing such in­dus­trial sys­tems to the ac­cel­er­a­tor con­trol area will cer­tainly ben­e­fit to the field in terms of fi­nance, human re­sources and tech­ni­cal fa­cil­i­ties of­fered off-the-shelf by the widely ex­pe­ri­enced in­dus­trial con­trols com­mu­nity; how­ever this can­not be done with­out slightly af­fect­ing the over­all ac­cel­er­a­tor con­trol ar­chi­tec­ture. The paper briefly de­scribes the in­dus­trial con­trols arena and takes ex­am­ple on an in­dus­trial process con­trol sys­tem re­cently in­stalled at CERN to dis­cuss in de­tail the re­lated choices and is­sues.
