There are two ways to upgrade a model that has already been created.
     One is to increase the version number and create a new model
     (if it becomes a new model configuration).
     Another is to update the version number, select the version you want to copy,
     and copy it. (When modifying the model configuration)
     This is under consideration and not available in the current version.

     A version consists of a major number, a minor number, and a revision.

    (1)  New model upgrade

       Click the new model in the menu [File] and select the model name to be upgraded.
       In the figure below, version 1.0.0 of the communication protocol has already been
      created, so change the version major, minor, and revision. Here we have revision 1.

             

       lick the New button to create a new model.
     

   (2) copy model upgrade

             The current version is under consideration and
            the copy version button is not available.
