Diagram Design
Using the Diagram editor allows mixing of functions, function blocks, diagram
instances and control modules in the same diagram. The diagram is based on
manual layout. This means the user can freely position blocks on the page.
The graphical connections are drawn using auto-routing. When two ports are
graphically connected the line will automatically be drawn in a free area, so that
blocks and labels are not crossed. When objects are moved the affected graphical
connections will be re-drawn.
In a single diagram it is possible to declare and use variables and communication
variables. In a diagram type it is possible to declare and use parameters and
variables.
When invoking functions or function block types in the diagram editor it is
recommended to not include the EN port, this ensures that the EN is set to true and
that the functions or function block types will be executed.
The diagram can have up to 100 pages.
