1. Create interface as in case of a basic model
2. When on the content page, to add an instance of a model type, press the "FB
Type" button and select a type from library
3. When the module appeared, call the pop-menu (right button), "Edit Properties" menu, and set the instance name in the "Name" field. Note that the field FBType already contains the type name of the module.
4. Insert other instances of models from the library and interconnect them with arcs.
5. Store the composite model as graphic file *.diag and export the model type in XML similar to that of basic models.
