A few weeks ago I described the possibility of storing more multiple configuration sets in a single model<\/a>.<\/p>\r\n\r\n

Today we will do the opposite: Sharing one configuration set among multiple models.<\/a><\/p>\r\n\r\n

Reference Configuration Set<\/strong><\/p>\r\n\r\n

By default, in Simulink, the configuration of a model is stored in the model file itself.<\/p>\r\n\r\n

However when you have a hierarchy of referenced models, those models must have similar configuration sets. Instead of having each model storing its own configuration, it is possible to have all models refer to a single configuration set.<\/p> \r\n\r\n

To begin, setup the configuration you want in one model and convert it to a configuration reference:<\/p>\r\n\r\n

\"Converting<\/p>\r\n\r\n

A dialog will allow you to specify the name of the configuration set and give you the possibility to save it to a MAT-file or a MATLAB script.<\/p>\r\n\r\n

\"Specifying<\/p>\r\n\r\n

Note that if you do not save the configuration set at this time, it is always possible to save it later using Simulink.BlockDiagram.saveActiveConfigSet<\/a><\/p>\r\n\r\n

Once the configuration object is in the base workspace, you can configure all your child models to refer to it:<\/p>\r\n\r\n

Update:<\/strong> This can be done by right-clicking on the top model configuration reference and selecting Propagate to Referenced Models<\/strong><\/em><\/p>\r\n\r\n

\"Multiple<\/p>\r\n\r\n

That way if the configuration needs to change, you will need to make the change in only one place.<\/p>\r\n\r\n

Creating Variants of a common configuration set<\/strong><\/p>\r\n\r\n

In a hierarchy of referenced models, it is common to want all the child models to have almost the same configuration, except a few parameters. For example, in the following model I want the three child models to have all the same configuration, except I want child3.slx<\/tt> to execute at a different sample time.<\/p>\r\n\r\n

\"Multiple<\/p>\r\n\r\n

To make that happen, I stored a configuration named myConfig<\/tt> in a MATLAB script configFile.m<\/tt>. In an initialization script that I execute before running my model (for example the model PreLoadFcn callback<\/a>), I copy this configuration set and modify the parameter I need.<\/p>\r\n\r\n

\"Creating<\/p>\r\n\r\n

That way, I can configure child3.slx<\/tt> to refer to myConfigTS2<\/tt>. If, in the future, I need to change a parameter in all the child models, I only need to do it once in configFile.m<\/tt>. When my initialization script will create myConfigTS2<\/tt>, it will automatically inherit this change.<\/p>\r\n\r\n

Now it's your turn<\/strong><\/p>\r\n\r\n
