  SSC-LINAC con­trol sys­tem is based on EPICS ar­chi­tec­ture. The sub con­trol sys­tem of dig­i­tal power sup­plies is a kind of IOC send and re­ceive cus­tom com­mand via Eth­er­net and TCP/IP pro­to­col. The old IOC is de­signed to use pe­riod scan mode IOC, and there are so many dig­i­tal power sup­plies, that we can't make sure every con­nect con­di­tion of dig­i­tal power sup­ply is fine. IOC must wait a long time if one of them can't con­nect cor­rectly and other dig­i­tal power sup­ply's PV may also be blocked. An IOC that uses in­ter­rupt dri­ven mode to avoid the short­com­ing was de­signed. This will be de­scribed in this paper.
