FB_BA_ShortLongClick
The function block FB_BA_ShortLongClick is used to differentiate between a short and long button press.
If the input bSwi is present for longer than nSwiOvrTi [ms], the output bLongClick is set for one PLC cycle. Otherwise, the output bShortClick is issued for one PLC cycle.
If a continuous signal is required for long button presses, the function block FB_BA_ShortLongPress must be used.
