6.2.5 Results data transfer with Ethernet
The results data can be transferred after process end (asynchronous) or before process end
(synchronous).
You can find a detailed sequence of the actual PLC signals in chapter 5 Control signals, from page 121,.
6.2.5.1 Results transfer after process end of an application or single-channel tightening
The following example for a tightening application can be transferred to single-channel tightenings by
replacing the signals for an application (FO x …) by the corresponding signals (CH x.y …).
Fig. 6–16: Chronological sequence for preparing and asynchronously transferring the tightening results after process end of a
tightening application
The actual end of the tightening application (tightening and process communication unit completed) is
indicated by the evaluation signals (FO x Ok, FO x Nok) switching from L to H. At this point, the
tightening spindles can be removed from the processed component.
The tightening cycle is ended (PLC signal FO x CyCmp) after the results have been prepared and saved
to the mass storage.
The data transfer is implemented independently from the tightening process.
