DPV1 acyclic communication
Base model parameter access, whose structure is
defined in the PROFIdrive profile 4.2, is always used
for communicating the writing/reading parameters for
PROFIdrive drives.
Under this arrangement, parameters access always consists
of two elements. Under this arrangement, parameter
access always consists of two elements.
Write request (“Write data set “)
Read request (“Read data set”)
Write request or Request can be send via DPV1 master
class 1 or master class 2.
The DP V1 command/response part is used for the standard
DP V1 read/Write on the Slot 0, Index47 data block.
Parameter requests and parameter responses
A parameter consists of three segments.
Request header
ID for the request and number of parameters which are
accessed. Multi-Axis and Modular drives, Addressing of
one DO.
Parameter address
Addressing of a parameter. If parameters are accessed,
there are correspondingly many parameter addresses but
can only be accessed on a single case. The parameter
address appears only in the request, not in the response.
Parameter value. Per addressed parameter, there is a
segment for the parameter values. Depending on the
request ID, parameter values appear only either in the
request or in the reply.
Words and double words
The following telegram contents are displayed in words (a
word or 2 bytes per line). Words or double words will have
the most significant byte being transmitted first (big endian).
