Hello @DonMario73,
A week ago we release V3.5.0 in this version Profinet is also supported.

If you would like to see an overview of the supported protocols, you can use this link OT supported protocols - Lansweeper Community
The IEC 60870-5-104 protocol is still in research phase. But it is quite possible that we can already interrogate the device with one of our other protocols. The best way to find out is to do a scan. If you have not yet tested the software, you can always contact me directly by email at filip.van.houtte @ lansweeper.com
