  Sev­eral RF Su­per­con­duc­tive LINAC pro­jects are un­der­way in dif­fer­ent lab­o­ra­to­ries around the world, with var­i­ous ob­jec­tives such as re­search in physics, ir­ra­di­a­tion tests, pro­duc­tion of ra­dioiso­topes for med­ical pur­poses. Su­per­con­duct­ing op­er­a­tion of the ac­cel­er­at­ing cav­i­ties re­quires them to be main­tained at cryo­genic tem­per­a­tures (2K - 4K) by the use of cryo­genic flu­ids. This re­quires a com­plete cryo­genic con­trol sys­tem, in­clud­ing sen­sors, ac­tu­a­tors, local con­trollers and PLCs. We de­scribe the process by which the pre­lim­i­nary de­sign of the cryo­genic con­trol sys­tem for the ac­cel­er­a­tor’s cry­omod­ules and valve boxes may be built. It starts with the func­tional and per­for­mance re­quire­ments of the sys­tem, fol­lowed by the de­f­i­n­i­tion of use cases and the study of the nec­es­sary cryo­genic in­stru­men­ta­tion. This leads to a pre­lim­i­nary de­sign of the ar­chi­tec­ture of the cryo­genic con­trol sys­tem using Siemens hard­ware, as well as cryo­genic se­quences de­scrib­ing stan­dard phases of op­er­a­tion of the LINAC. We also dis­cuss how to take ad­van­tage of the mod­u­lar­ity of cry­omod­ules for con­trol sys­tem im­ple­men­ta­tion and some re­cent de­vel­op­ments in PLC sim­u­la­tion.
