FindServersOnNetwork service?
Unless, of course, you have some other OPC client that uses FindServersOnNetwork to connect to LDS-ME and DOES return some servers - which would then require investigation as to why QuickOPC's result are different.
But in general, for LDS-ME to return servers:
- The servers running on the same machine as the LDS-ME need to be configured to register with LDS-ME - which normally also includes configuring the UA security for them because registering the server with LDS-ME is security sensitive.
- If there are other LDS-ME servers on the network, the network must allow the proper mDNS (UDP) traffic between them.
- Servers on other machines need to be configured to register with their respective LDS-ME servers on those machines.

Thank you for your answer.
The local discovery server is running on my machine. When I am using "localhost" I don't get any UA server in the list.
The discoveryElementCollection is empty.
I appreciate your advise.

It must be the name of the host where you/the customer have installed the LDS-ME server.
It can be "localhost" if the LDS-ME is on the same computer as the client, or some other host name.
This is where the DiscoverNetworkServers methods gets the information from.

My question was what is the meaning of the "opcua.demo-this.com" parameter?
discoveryElementCollection = client.DiscoverNetworkServers("opcua.demo-this.com")
Can it be something else?
I have other OPC UA servers, for example PROSYS but the discovery using your sample code doesn't discover it.
Thanks,
Michael

What should be the parameters for the function: discoveryElementCollection = client.DiscoverNetworkServers() ?
Currently it is: "opcua.demo-this.com", flat:=False
Thank you.

Is it possible to browse for OPC UA server using QuickOPC client .Net using the FindServersOnNetwork service?
Thank you.
