Appendix A Operation manual 12 12.3.1 DPV1 telegram frame Normal case The following four DPV1 telegrams are used to transmit a parameter job/ parameter response pair: Transmission of the parameter job in a DPV1 write request DPV1-Write-Header Function_Num = 5F hex (write) Slot_Number = ... Index = 47 Length = (data) DPV1-Data (length) Parameter job ... ... 1. Abbreviated acknowledgment of the parameter job with the DPV1 write response (without data): DPV1-Write-Header Function_Num = 5F hex (write) Slot_Number = (echoed) Index = (echoed) Length = (echoed) 2. Request for the parameter response in a DPV1 read request (without data): DPV1-Read-Header Function_Num = 5E hex (read) Slot_Number = Index = 47 Length = MAX 3. Transmission of the parameter response in the DPV1 read response: DPV1-Read-Header Function_Num = 5E hex (read) Slot_Number = (echoed) Index = (echoed) Length = (data) DPV1-Data (length) Parameter response ... ... Meaning and use of the elements in the DPV1 header: • Function_Num: ID for DPV1 service (read, write, error). • Slot_Number: DPV1: In the request: Addressing of a real or virtual module on the slave. In the response: Echoed. PROFIDrive: No evaluation WE KEEP THINGS MOVING ID 441687.03 47
