The traditional experimental beamline station scanning synchronization control generally adopts a software processing mode, which results in a long scanning time, low scanning efficiency, and poor synchronization accuracy due to the existence of a large amount of dead zone time. Since March 2022, we have upgraded the original motion control system on the XMCD beamline station of the Hefei Light Source and improved the design of PANDABOX. At the same time, we have used the control framework of Bluesky to achieve the first energy fly-scan experiment at the Hefei Light Source. Experimental tests have shown that compared with step scan method, the experiment data quality of the energy fly-scan experiment is better, the scanning efficiency is higher, and the synchronization accuracy is higher. This provides useful reference for the technological development of the control field of the beamline station in the upcoming Hefei Advanced Light Source.
