Writing password settings to the display unit
Using the HMI system variable #H_SecurityWriteStatus, you can check whether the reflecting action to the display unit is completed successfully.
If external storage is not inserted, the data cannot be reflected on the display unit, and 0100 (No external storage) is stored in the HMI system variable #H_SecurityWriteStatus.
For details on HMI system variables, see the following.
A.2.2 HMI System Variables - #H System Variables
If the power goes off while writing password settings to the display unit, the file may get corrupted. When this happens, password settings cannot be read when starting up the display unit. An error message appears after the startup. In such a scenario, transfer the project again.
