STXPNS001 Devices on a PROFINET subnet must have unique names. The device names
must satisfy the following DNS naming conventions:

Device names are assigned to PROFINET IO device when the device is being set up and
placed in operation for the first time ("commissioned").
The default name is "STXPNS001-SW".
If several devices of the same type are arranged on the same PROFINET IO system, then
PME/ Programing software automatically adds sequential number to the name from the GSD
file. In this case, the second device has the extension "-1", the third one has the extension "-
2", and so on.
