When it is necessary to update or add equipment and connect it to the local controller of the EMS (Energy Storage Management System), it is often necessary to manually perform cumbersome configuration work on the local controller of the EMS (Energy Storage Management System) according to the communication protocol provided by the manufacturer. This process not only takes a long time, but may also cause communication failures due to configuration errors, thereby affecting the overall operation efficiency and stability of the system. Summary of the Invention

[0100] In this embodiment, it is also necessary to determine whether the measured point data set is empty. When the measured point data set is not empty, the measured point configuration content in the measured point data set is exported in the form of EXCEL, and the program records the relevant operation logs. Moreover, the exported EXCEL file can be used for manual configuration.
