The starting port number is greater than or equal to the ending port number.

Cause:

The GDI and GDO port numbers are set incorrectly: the start port number is greater than the end port number.

Troubleshooting:

Check whether the start port number of the GDI and GDO reporting the error is greater than the end port number.

Solution:

Modify the port number range.

Case sharing:

The GDO ports are configured as: 5-3
Using this GDO then reports error 361.
