Hello

I am trying to connect to an opc server. Works fine with uaexpert and also with siemens own client interface.

Something is wrong with my plc connection though. As soon as i set connect i get busy and error 8601 which means Error during connect (SFB "OPC_UA_Connect"). The server does not even react to the connection attempt.

Am i missing something obvious here?

Cheers

TIA18 and PLCSIM Advanced and microsofts and iot-edge-opc-plc server.

Cheers

In comparison, a connect and disconnect with uaexpert looks like this:

Last command before closing is:

[11:20:05 INF] TCPSERVERCHANNEL ProcessCloseSecureChannelRequest success, ChannelId=4, TokenId=1, Socket=0001A610

 So it seems my tia portal-connection immediately closes itself down.
