Our "LSB VSM" driver already supports both port numbers and input/output label names. I used it already in some projects.

In the past, I received similar question from another user and in the end they did a change inside the VSM software and then the labels appeared in DataMiner. I personally never used the VSM software directly, but I seem to remember they had to 'add inputs/outputs to virtual matrices' inside VSM. I'll check if I can bring you in contact with that user and let him reply on this post if possible (unless someone else already knows the answer before that ofcourse 🙂 )
