Project Tags
The project tags were created to simplify the configuration of the module. Some of the
tags defined in the sample project utilize the user defined data types described in the
previous section.
The user defined tags from the controller scope should be copied to your project before
the tags contained in the individual program sections. Open the controller tags on the
sample project and select the edit tags mode . Grab the tags you want to copy by using
the left mouse button and dragging. See figure below.
