6.3.2 Configuring the DP/PA link
Configure the DP/PA link with your configuration tool (e. g. COM PROFIBUS) as
you would any other DP slave on PROFIBUS-DP.
To do so, load the complete device master file for the DP/PA link into your
configuration tool.
Parameter assignment and configuration frame
The frame length for the parameter assignment depends on the number of PA field
devices in use and must not exceed 214 bytes.
The frame length for the configuration depends on the number and extent of PA
field devices in use and must not exceed 244 bytes.
The structure of the parameter assignment and configuration frames is found in
Article No. 13406349 on the Internet:

Restrictions
Functions based on reading the configuration before parameters are initially
assigned to the DP/PA link are not supported. For this reason the CP 5431, for
example, cannot be used as a DP master. Likewise, variables cannot be controlled
with the COM PROFIBUS before parameters have been assigned for the DP/PA
link.
