Cause:
The ConfigureFiles directory in the controller's ftp contains no ID_CHS.xml or ID_EN.xml file.
Troubleshooting:
Go to ftp://192.168.39.220/ConfigureFiles/ and check whether ID_CHS.xml or ID_EN.xml exists.
Solution:
Contact after-sales support and copy the corresponding ID file to the controller.
Case sharing:
None.
