Troubleshooting: Open URL via Datasocket and Connecting to Network

[mrcs89]

Hello community!

I'm using an OPC-Server from Eurotherm. The data are read via Data-Socket
(i don't know a different way).

If the OPC-Server runs on the same PC(localhost) everything works fine.

If the OPC-Server runs on a different PC in the same network, the trouble begins.

On the picture below you see a try to have a look on the network via "datasocket select url vi". 

Switching off the firewall or open specific ports does not work. The error still occurs.

I've tested it on different labview versions(2020 and 2016). So i guess it's something simple.

Thanks in advance for your help.
