Notice that for the online view of a function block POU: In the implementation part no
values will be viewed in the monitoring windows but "<Value of the expression>" and
the inline monitoring fields in the implementation part will show three question
marks each.
Breakpoint positions in CFC Editor:
The possible breakpoint positions basically are those positions in a POU at which
values of variables can change or at which the program flow branches out resp.
another POU is called. See possible positions in the following picture.
Abb. 320 Breakpoint positions in CFC Editor
Notice for breakpoints in methods: A breakpoint will be set automatically in all
methods which might be called. So, if an interface-managed method is called,
breakpoints will be set in all methods of function blocks implementing that
interface and also in all derivative function blocks subscribing the method. If a
method is called via a pointer on a function block, breakpoints will be set in the
method of the function block and in all derivative function blocks which are
subscribing the method.
