  RIKEN Ra­dioac­tive Iso­tope Beam Fac­tory (RIBF) is a cy­clotron-based heavy-ion ac­cel­er­a­tor fa­cil­ity for pro­duc­ing un­sta­ble nu­clei and study­ing their prop­er­ties. Many com­po­nents of the RIBF ac­cel­er­a­tor com­plex are con­trolled by using the Ex­per­i­men­tal Physics and In­dus­trial Con­trol Sys­tem (EPICS). We will here pre­sent the overview of the EPICS-based RIBF con­trol sys­tem and its lat­est up­date work in progress. We are de­vel­op­ing a new beam in­ter­lock sys­tem from scratch for ap­ply­ing to some of the small ex­per­i­men­tal fa­cil­ity in the RIBF ac­cel­er­a­tor com­plex. The new beam in­ter­lock sys­tem is based on a pro­gram­ma­ble logic con­troller (PLC) as well as the ex­ist­ing beam in­ter­lock sys­tem of RIBF (BIS), how­ever, we newly em­ploy a Linux-based PLC-CPU on which EPICS pro­grams can be ex­e­cuted in ad­di­tion to a se­quencer in order to speed up the sys­tem. After op­ti­mize the per­for­mance of the sys­tem while con­tin­u­ing op­er­a­tion, we plan to ex­pand the new sys­tem as a suc­ces­sor to the BIS that has been work­ing more than 10 years since the start of its op­er­a­tion.
