  At LNL it is being car­ried out an up­grade cam­paign of the con­trol sys­tems of the ac­cel­er­a­tor com­plex. The two main goals are stan­dard­iza­tion of hard­ware and soft­ware and sys­tem in­ter­op­er­abil­ity. EPICS has been cho­sen as the stan­dard frame­work for de­vel­op­ing new con­trol sys­tems; this will ad­dress soft­ware stan­dard­iza­tion and sys­tem in­ter­op­er­abil­ity. In order to achieve hard­ware stan­dard­iza­tion, a new EPICS IOC is under de­vel­op­ment, which will be­come a basic con­struc­tion block for all fu­ture con­trol sys­tems. The COM (Com­puter-on-Mod­ules) from fac­tor has been cho­sen as the hard­ware plat­form for the IOC, along with the pe­riph­eral de­vices needed for de­vel­op­ing all the fore­seen con­trol sys­tem at LNL. Pro­to­types of this IOC has been de­vel­oped using ADLINK's Type 6 COM Ex­press mod­ules on generic car­rier boards with DIO, ADC and DAC ex­pan­sion boards. These pro­to­types have been tested under typ­i­cal ap­pli­ca­tions at LNL in order to val­i­date the hard­ware plat­form choice. Ex­per­i­men­tal re­sults show that the per­for­mance of the IOC in terms of ef­fec­tive res­o­lu­tion (ENOB and bias error), sam­ple rates and CPU usage is suit­able for sat­is­fy­ing the re­quire­ments of the con­trol sys­tems.
