This paper introduces the design of the digital power supply control system for High Energy Photon Source, whose hardware includes an embedded edge computing controller Atlas 200 and a digital power supply control module. EPICS IOC runs on the main control module Adas 200, whose device driver is developed based on StreamDevice. EPICS IOC communicates with DPSCM through Modbus - TCP protocol to realize the remote control of magnet power supply and possible future smart control capability. The user interface is developed with CS-Studio, which can directly control and protect the power supply operation. The system has completed the offline test, and the control functions can operate normally.
