OPC UA Client

[lynn4001]

Hi All,

I am developing a OPC UA Client which aims to connect with a remote OPC sever over internet. It always give me the error -356694: The OPC UA server does not support the specified message mode. But I am sure the Endpoint Url is right and both Security Policy and Messahe Security Mode is None. I tried with another software to connect with this OPC Server, it works fine.

I attached the Block Diagram and error msg. Is it something wrong with the configration? It would be appreciated if you have some similar examples using OPC UA client blocks to connect remote OPC server.

Hope someone gives me hints.

Best,

Lin

Same problem. LabVIEW 2021, OPC UA toolkit, CLP Siemens S7 1200.

IP adress and "None" option for security policy seems correct.

Error message: OPC UA Toolkit: The OPC UA server does not support the specified message mode.

Hope for help.
