The tightening cycle is ended (PLC signal Ch x.y CyCmp) after results processing(buffering on the controller).Results output by the controller with the printer protocol is performed using the data from the buffer, independentlyof the tightening process.NoteResults output is not always completed after a sequence end for single-channel tightenings.System 350 | 3 608 878 040/05.2008
