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.
