Shortcut: <F8>
A single step is executed. The program is stopped before the first instruction of a called POU.
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 function exactly as 'Online' 'Step over'.
