Hi Ludo Houben,
I understand that you are trying to verify the appropriate connection of simulink.bus within a matlab.system block.
To verify the connection check the properties of the expected Simulink.Bus Element, such as its Name, dimensions, or datatype with the correct Simulink.Bus. In MATLAB, you can utilize the "get_param" function to effectively address this matter.
You can follow below given example to resolve the issue,
% Provide the actual block path
% You can get the block path using find_system.
blockPath = 'path_to_the_block';
% 'Parameter' can be Name, DataType or Dimensions
% Mention the parameter you want to validate
connectedBus = get_param(blockPath, 'Parameter');
% check if the connectedBus and expectedBus are equal - isequal
You can refer to the following documentation to understand more about "get_param" and "find_system" functions in MATLAB.
