Index (data block):
DPV1: In the request: Addressing of a data block on the slave. In the
response: Echoed.
PROFIDrive: Data block number 47 defines for parameter jobs and
responses.
•
Length:
DPV1: In the write request and read response, the length of the transferred
data in bytes.
PROFIDrive: Length of the parameter job/response.
DPV1: Length of the parameter job/response.
PROFIDrive: Maximum possible length.
DPV1: In the write response, the data length accepted by the slave.
PROFIDrive: Echoing of the length from the write request.
Errors
In case an error occurs, a DPV1-read or write request is answered with an error
response:
4) DPV1 error response:
•
Error_Decode
DPV1: ID, to be interpreted like Error_Code1/2.
PROFIDrive: Always 128 (DPV1 codes)
•
Error_Code_1
DPV1: Division into error class (4 bits) and error code (4 bits)
•
PROFIDrive
Use of certain numbers
•
Error_Code_2
DPV1: User-specific
PROFIDrive: Not used (always = 0).
