The following table shows the coding of a negative response of a PROFIdrive service.
Bit 7 is entered in the Response ID if the response is negative.
Service Read.response
Slot_Number 0 Random (is not evaluated)
Index 47 Index of the dataset; constant index 47
Length 4 4 byte user data in response buffer
Byte Field Value Description
0 Response reference 0x01 Reflected reference number from the parameter setting
order
1 Response ID 0x02 Positive PROFIdrive response
2 Axis 0x00 Reflected axis number; 0 = Single axis
3 No. of parameters 0x01 1 parameter
