Communication via OPC-UA to a non-local server

[BrunoNascimentoGomes]

Im trying to access a variable from a server running in another device using a Client_FB, but I keep receiving this errors:

Im using Codesys to generate a OPC UA server at a PLC, so it creates the server this way:

So I used this "opc_ua[READ;opc.tcp://192.168.2.20:4840#;/Objects/CPX-CEC-C1-V3/Application/PLC_PRG/posicao_atuador_avancoo]" at the ID from the Client FB. But it keeps returning errors.

What should I do?

Problem solved, just wrote the ID using only the NodeID, so it will look like this: opc_ua[READ;opc.tcp://192.168.2.20:4840#;,2:s=|var|CPX-CEC-C1-V3.Application.PLC_PRG.posicao_atuador_avancoo].

I got the NodeId using UAExpert.

Hope I can help.

As the error messages says above the intermediate nodes are missing. The OPC UA implementation of 4diac FORTE does only create the last node in the line. If you need intermediate nodes you need to create them as described in our OPC UA documentation.
