2 Function
The Festo Quickstepper is a sequence controller wired ready for connection with
12 switch steps.
An input is assigned to each output. The Quickstepper controls the movement
sequence in a performance−related manner: It does not switch to the next step
until it has been reported to the appropriate input that the previous movement has
been executed. The Quickstepper thus enables a reliable diagnosis in the event of
an error: Should there be no acknowledgement signal (blue pin not visible), the
error can be localised very quickly via the appropriately displayed step an the
circuit diagram.
