6.5.3.2 Results output in a single-channel tightening
Fig. 6–67: Chronological sequence for processing and transferring tightening results for a single-channel tightening via the printer
protocol
Due to the hardware buffering in the data interfaces, parts of the printer protocol may be output only after
process end (CH x.y CyCmp). For complete data transfer, you must wait for the protocol end ("ETX" end
trigger character 0x03).
Here, the actual tightening end is also indicated by the evaluation signals (CH x.y Ok, CH x.y Nok)
switching from L to H. At this point, the tightening spindle can be removed from the processed
component.
The transfer is started once the results have been processed. After the results have been transferred
successfully, the tightening cycle is ended (control signal CH x.y CyCmp).

In version 2.1 and below, the results output is not necessarily completed after a process end for single-
channel tightening.
