CHIMERA is an ex­per­i­men­tal nu­clear fu­sion test fa­cil­ity which aims to sim­u­late the in­tense mag­netic fields and tem­per­a­ture gra­di­ents found within a toka­mak fu­sion re­ac­tor. The con­trol sys­tem at CHIMERA is based on EPICS and will have ap­prox­i­mately 30 input/out­put con­trollers (IOCs) when it comes on­line in 2024. It will make heavy use of CSS Phoe­bus for its user in­ter­face, se­quencer and alarm sys­tem. CHIMERA will use EPICS Archiver Ap­pli­ance for data archiv­ing and EPICS areaD­e­tec­tor to ac­quire high speed data which is stored in the HDF5 for­mat. The con­trol phi­los­o­phy at CHIMERA em­pha­sises PLC based con­trol logic using mostly Siemens S7-1500 PLCs and using OPCUA to com­mu­ni­cate with EPICS. EPICS AU­TOSAVE is used both for man­u­ally set­ting lists of process vari­ables (PVs) and for au­to­matic restora­tion of PVs if an IOC must be restarted.
