Attach a config set from a data dictionary to a model programmatically

@Marcus In the following you can find an example code, which gets the Configuration object stored in a Data Dictionary and this configuratin then gets set in a configuration reference linked to a model. Please let me know what else is missing, so I can provide you any further information. I believe your code above missed the getValue method to actually get the configuration object.

% get referenced configuration from "myNewDictionary.sldd"
dictionaryObj = Simulink.data.dictionary.open('myNewDictionary.sldd');
configsSectObj = getSection(dictionaryObj,'Configurations');
entryObj = getEntry(configsSectObj,'myConfig1');
myConfig1 = getValue(entryObj);
% open the model
open_system('testcase');
% create a configuration reference
Reference = Simulink.ConfigSetRef;
% set the source name of this configuration reference as the configuration
% set in data dictionary
set_param(Reference,'SourceName','myConfig1');
% attach the referenced configuration (myConfig1) to the model
attachConfigSet('testcase',Reference)
setActiveConfigSet('testcase','Reference')

I can only imagine that one could store the reference in the dictionary itself to make it easier to share this reference and directly attach it to a model in a programmatic workflow. But in my case it was just an example on how to create such objects and link them, I had no clear use case in mind.

In the following you can find the code for that, the only change was to link the model to the Data Dictionary (if this is already the case it is not needed) and then attach the configuration reference to the model:

dictName = 'myDD.sldd';
mdl = 'myExpMdl';
nameOfConfigRef = 'myConfigRef';
% dictionaryObj = Simulink.data.dictionary.open(dictName);
% configsSectObj = getSection(dictionaryObj,'Configurations');
% allEntries = configsSectObj.find('-class','Simulink.data.dictionary.Entry');
% assert(isa(allEntries.getValue,'Simulink.ConfigSet'))
%if you know the name of the Configuration you can use it directly
nameOfConfig = 'myNewDDConfig';
configRef = Simulink.ConfigSetRef;
set_param(configRef,'SourceName',nameOfConfig);
set_param(configRef,'Name',nameOfConfigRef);
set_param(mdl,'DataDictionary',dictName);
attachConfigSet(mdl,configRef);
setActiveConfigSet(mdl,nameOfConfigRef);

Yes, that is correct.

Do you have any further questions?
