A running application will stop at a breakpoint:
Now you can step further by using <F8>, which represents command Step Into from
the Debug menu and therefore will step also into the function block instance. To skip
the steps of the function block use <F10> which equals the command Step Over. Each
variable value currently read from the PLC will be displayed.
You might also have a look at the breakpoints dialog to be opened via command
Breakpoints from the View menu. Here, the breakpoints currently set can be viewed
and edited and new breakpoints might be entered.
Notice also that the breakpoint positions will be remembered when you log out. They
will be indicated by faded red bullets.
