Shortcut: <F10>
This command causes a single step to execute. If a POU is called, the program stops after its execution.
If the present instruction is the call-up of a function or of a function block, then the function or function block will be executed completely. Use the 'Online' 'Step in' command, in order to move to the first instruction of a called function or function block.
If the last instruction has been reached, then the program will go on to the next instruction in the POU.
