6.4.5 Results data transfer with field busses
Results output is implemented via an interface module in the communication unit or compact system. For
tightening applications, results output is possible via the communication unit.
6.4.5.1 Results data transfer for an application
Fig. 6–57: Chronological sequence for processing and transferring the tightening results via field bus for an application
Here, the actual end of the application is also 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. 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
FO x CyCmp is set. This process is initiated by the master.
All chronological sequences are listed in chapter 5, Control signals, from page 121. In this chapter you
can find several examples for clarification of the field bus communication function.
The following chronological sequences do not apply to the multitelegram function. Multitelegrams require
that the data be actively requested from the communication partner after CyCmp.
(A) Application
(B) Data buffer result (field bus)
FO x Cw Start
FO x InCy Sequence active
FO x CyCmp Process end
FO x Ok Process OK
FO x ResRs Result reset
(1) Cycle
(2) Invalid
(3) Result valid
