Creating a concurrency diagram
Construct the Concurrency Diagram in the same way as you do for other diagrams, by using the toolbar icons to add items to the diagram, or by dragging items from the dictionary onto your Concurrency Diagram.
A Concurrency Diagram represents part of a Concurrency Model, which you can construct in the dictionary and then represent on a diagram.
A Concurrency Diagram includes the following elements:
Task
Interface device
Messaging
Concurrency primitive
Linking items
