Default shortcut: F10
The Debug > Step Over command 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 into (that is, 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 have to use the Step Into command.
