At this point, the nutrunner can be removed from the processedcomponent.The tightening cycle is ended (PLC signal Ch x.y CyCmp) after results processing (buffering on thecontroller). The results are then written from the buffer to the data buffer in the IMpdp interface module.The data transfer is initiated by the master.NoteResults output is not always completed after a sequence end for single-channel tightenings. The resultsvalues cannot just be taken over by the master after the sequence end. The master must ensure that thedata is taken over correctly.7.4.6 Error messages in connection with Profibus DPTable 7–40: Error list IMpdp at interface AError number(internal)Error classError text850 1 Initialization error PDP card855 1 Memory error IMpdp860 1 Parameter telegram for IMpdp invalid865 1 Invalid number of I/O points (KE slave != master)870 3 MasterIMpdp connection disrupted875 1 Maximum number of IMpdp drivers exceeded880 1 IMpdp station address invalid885 1 I/O area cannot be reserved890 1 PLC pointer invalid895 1 Hardware monitoring -> Transfer errorSystem 350 | 3 608 878 040/05.2008
