  Su­perKEKB is the up­grade of KEKB, the asym­met­ric en­ergy elec­tron-positron col­lider for the B-fac­tory ex­per­i­ment in Japan. It aims at the 40-times higher lu­mi­nos­ity than the world record by KEKB. The KEKB con­trol sys­tem has been built based on EPICS at the equip­ment layer and script­ing lan­guages at the op­er­a­tion layer. The Su­perKEKB con­trol sys­tem con­tin­ues to em­ploy these frame­works while we im­ple­ment new fea­tures for the suc­cess­ful op­er­a­tion at such a high lu­mi­nos­ity. As the com­mis­sion­ing of the Su­perKEKB main stor­age rings is sched­uled to start in 2016, the con­struc­tion of the con­trol sys­tem is now in the final phase. We have up­graded and re­in­forced the net­work sys­tem, server com­put­ers and op­er­a­tor con­soles. Most of the VME-based IOCs (I/O Con­trollers), which has been widely used in KEKB, are up­graded while the PLC-based IOCs are also widely in­tro­duced. The new tim­ing sys­tem has been de­vel­oped in order to han­dle the com­pli­cated in­jec­tion scheme of the Su­perKEKB ac­cel­er­a­tor com­plex ef­fi­ciently. The new beam abort trig­ger sys­tem and the new beam gate con­trol sys­tem have been de­vel­oped, and so on. The con­struc­tion sta­tus of the Su­perKEKB ac­cel­er­a­tor con­trol sys­tem will be pre­sented.

  There were more than 2500 mag­net power sup­plies for KEKB stor­age rings and in­jec­tion beam trans­port lines. For the re­mote con­trol of such a large num­ber of power sup­plies, the Power Sup­ply In­ter­face Con­troller Mod­ule (PSICM), which is plugged into each power sup­ply, was de­vel­oped. It has a mi­cro­proces­sor, AR­C­NET in­ter­face, trig­ger sig­nal input in­ter­face, and par­al­lel in­ter­face to the power sup­ply. The PSICM is not only an in­ter­face card but also con­trols syn­chro­nous op­er­a­tion of the mul­ti­ple power sup­plies with an ar­bi­trary track­ing curve. For Su­perKEKB we have de­vel­oped the up­graded ver­sion of the PSICM. It has the fully back­ward com­pat­i­ble in­ter­face to the power sup­ply. The en­hanced fea­tures in­cludes high speed AR­C­NET com­mu­ni­ca­tion and re­dun­dant trig­ger sig­nals. To­wards the phase 1 com­mis­sion­ing of Su­perKEKB, the con­struc­tion of the mag­net con­trol sys­tem is on­go­ing. First mass pro­duc­tion of 1000 PSICMs has been com­pleted and their in­stal­la­tion is in progress. The con­struc­tion sta­tus of the mag­net con­trol sys­tem is pre­sented in this paper.
