Hi Flo, Which TIA version is it exactly? In V14 SP1 U1 it shows "PLCIM" in PG/PC settings only, Ethernet configuration on S7-1500 should not affect PLCSIM as TIA handles it internally and disables any online connections. Regards, Raphael

Maybe it makes sense to show only known adapters in state Up and have a checkbox to enlist all adapters as an option. Might be helping to keep the initial list "small".

When talking about Ethernet there may be IPv6, at least as network address (not plc). It might be uncommon (like using wireless). Have you ever tested using IPv6?

OpenVPN (tun adapter) will be listed as Ethernet, also some others. IP-Address, adapter description, adapter type Microsoft lists some more types, but I have never seen others than Ethernet for wired adapters. https://msdn.microsoft.com/en-us/library/system.net.networkinformation.networkinterfacetype(v=vs.110).aspx Edit: Image shows all adapters available at my notebook, last value is NetworkInterfaceType.

Hi Thomas, seems it is the NetworkInterfaceType in Form_Load(). Checking for NetworkInterfaceType.Wireless80211 will solve this. You may also check (or display) any operational status, as it will show almost all adapters on system. [snip] NetworkInterface[] intf = NetworkInterface.GetAllNetworkInterfaces(); foreach (NetworkInterface device in intf) { if (device.OperationalStatus == OperationalStatus.Up) { if (device.NetworkInterfaceType.Equals(NetworkInterfaceType.Ethernet) || device.NetworkInterfaceType.Equals(NetworkInterfaceType.Wireless80211))...
