I'm using OPC UA Read and Write blocks within a Simulink model. I want to create a simulation app (by selecting 'Simulation App...' from the 'Save' dropdown menu. However, the creation fails because the OPC UA classes do not support code generation.

Are there any plans to make them compileable? Alternatively, is there a workaround? I've tried to create bespoke read and write OPC UA blocks, but run into the same problem.

Thanks,

I can reckon that you are having issues with the 'OPC UA Read' block and the 'Write' block in Simulink when creating a simulation app, due to the lack of code generation support.

For a detailed answer, you can refer to the following post on the MATLAB Answers community, which addresses the same issue: https://www.mathworks.com/matlabcentral/answers/2099686-do-opc-ua-blocks-in-simulink-work-with-code-generation

I trust this response will guide you towards resolving your query.

Thanks for confirming OPC UA Simulink blocks can't be compiled. Do you know if there's a workaround or if MathWorks intends to make this available in the future?
