Communication protocol 151
Subsequent response frames:
 DP-V1 read/write request sequence
A read/write service on a drive parameter is illustrated below.
The messaging employs DP-V1 data units. The PROFIdrive
parameter request is included within the DP-V1 request as data.
Likewise, the DP-V1 response contains the PROFIdrive parameter
response as data.
A write request (Function number 5Fh – see page 154) is first sent
containing the parameter request.
If the write request is valid, the adapter module acknowledges it
with DP-V1 write response code 5Fh with no data. The master will
then send a read request. If the adapter module is still busy
