Errors
In case an error occurs, a DPV1-read or write request is answered with an error
response:
4) DPV1 error response:
DPV1 error
Function_Num= DF hex (error write)=
DE hex (error read)
Error_Code_1
Error_Decode = 128 (DPV1)
Error_Code_2 = (don't care
always = 0)
• Error_Decode
DPV1: ID, to be interpreted like Error_Code1/2.
PROFIDrive: Always 128 (DPV1 codes)

DPV1: Division into error class (4 bits) and error code (4 bits)
• PROFIDrive
Use of certain numbers
• Error_Code_2
