Hello,
there may be multiple reasons for this.

In order to investigate, I need more details about the error. Can you please provide the full error message, and the call stack (from the Exception object).
And, if there this a non-null value in the InnerException property, continue recursively - the full message text, and its call stack - etc.

Thank you

Hello OPC-Labs team,

In our company we work with various PLC controls or OPC UA servers. All controls provide at least over 2000 nodes.

Due to the OpcUa server restrictions, it is not possible for us to map the nodes in the entire mapping call, as the server acknowledges this request with a BadRequestTooLarge error message. Which is probably due to the limited MaxMessageSize.

Is it possible to adopt the restrictions of the OpcUa server on the UaEasyClient side? If so, how can I specify these parameters on the client so that it communicates with the appropriate message size?

We work with the OpcLabs version 5.54.1311.

Kind regards
