12.3.5 Step Into
Symbol:
Default Shortcut: <F11>
This command (category Breakpoints) can be used for stepping through a program in
online mode, for example for debugging purposes.
A single step will be executed. The program will stop before the next instruction. If
necessary there will be a changeover to an open POU. If the present position is a call-
up of a function or of a function block, then the command will proceed on to the first
instruction in the called POU.
In all other situations, the command will act like 'Step Over'.
The possible halt positions during stepping depend on the editor. The current position
is indicated by a yellow shading.

12.3.6 Step Over
Symbol:
Default Shortcut: <F10>
This command (category Breakpoints) can be used for stepping through a program in
online mode, for example for debugging purposes.
A single step will be executed. With one-level instructions this is equal to stepping
with 'Step In' (i.e. from instruction to instruction). If however a POU call is reached,
then Step Over effects that this POU will be executed completely within the current
step. In SFC a complete action will be executed.
If you would like to jump to the first instruction of a called POU, you had to use the
'Step Into' command.
Notice also: Step Out
