Results output via a compact system
Fig. 6–58:
Chronological sequence for processing and transferring the tightening results via field bus for a tightening process in the
compact system
Here, the actual tightening end of the tightening process is also indicated by the evaluation signals (Ok,
Nok) switching from L to H. At this point, the tightening spindle can be removed from the processed
component.
After results processing, the data buffer with the results values is transferred to the field bus module. The
field bus master can collect the results data from the data buffer after the process end signal CyCmp is
set. This process is initiated by the master.
