Reverse and Display value attribute on data types in diagrams
As an result of the execution order described in Execution order on page 60, the
reverse attribute will work for control modules in diagrams.
Split and Join functions shall not to be used with structured data types containing
components with the reverse attribute. Functions and function blocks cannot handle
reverse attributes.
For diagrams there are also a attribute Display value for datatype. If the attribute are
set for a component in a datatype this value will be shown in online mode for the
connection.

Bi-directional logic is handled by Control Module types, but it is possible to use a
diagram type as well. The forward signal flow can be implemented in the diagram
