MATLAB: Can’t I see the bus object after using simulink.Bus.CreateObject

simulink

I'm trying to create bus objects from "Bus Creator" blocks with:

>> simulink.Bus.CreateObject(model, blocks)

This seems to work for the example models supplied in the documentation. For a working demo, my base workspace shows:

However, when using it on my model, I only get a struct – the bus object seems to be missing:

If the model has a linked data dictionary (SLDD), then the bus object definition will be located there instead of the base workspace. The doc was updated starting in R2019b to reflect this.

R2019a doc (mentions output to base workspace)

R2019b doc (mentions output to base workspace and SLDD)

MATLAB: Rename BUS

Hi,

if you create a sample BUS with the bus editor you can export the BUS in the Model Explorer (Ctrl + H) of your Simulink Model (Base Workspace). It will generate an .m-file where you can set the bus names and run on model startup:

% -------------------------------------------------------------------

%  MATLAB file generated by Simulink.saveVars 
% -------------------------------------------------------------------
FA = Simulink.Bus;
FA.Description = '';
FA.DataScope = 'Auto';
FA.HeaderFile = '';
saveVarsTmp{1} = Simulink.BusElement;
saveVarsTmp{1}.Name = 'cog';
saveVarsTmp{1}.DataType = 'double';
saveVarsTmp{1}.Complexity = 'real';
saveVarsTmp{1}.Dimensions = 1;
saveVarsTmp{1}.DimensionsMode = 'Fixed';
saveVarsTmp{1}.SamplingMode = 'Sample based';
saveVarsTmp{1}.SampleTime = -1;
saveVarsTmp{1}(2, 1) = Simulink.BusElement;
saveVarsTmp{1}(2, 1).Name = 'mass';
saveVarsTmp{1}(2, 1).DataType = 'double';
saveVarsTmp{1}(2, 1).Complexity = 'real';
saveVarsTmp{1}(2, 1).Dimensions = 1;
saveVarsTmp{1}(2, 1).DimensionsMode = 'Fixed';
saveVarsTmp{1}(2, 1).SamplingMode = 'Sample based';
saveVarsTmp{1}(2, 1).SampleTime = -1;
FA.Elements = saveVarsTmp{1};
clear saveVarsTmp;
