Cause:
In the ConfigureFiles directory of the controller's ftp, the missing Workspace.xml has a format that does not match the software version.
Troubleshooting:
Check whether there is a SpaceCheck node at the end of Workspace.xml under ftp://192.168.39.220/ConfigureFiles/.
Solution:
Contact after-sales personnel, copy Workspace.xml from the controller's ftp, and send it to after-sales personnel.
Case sharing:
None.
