3.11.1 DP Configuration Data
The configuration of the Profibus interface normally happens using the
GSD file. It is initially imported into the "Device Catalog" of the configu-
ration software. Subsequently, the Profibus interface can be
“dragged”
into the bus system and then be configured.
With the configuration, the user can individually adapt data width within
the data transfer. Identifiers with data widths of 1 to 16 bytes maximum
are possible.
By specifying these identifiers in any order, the desired total data width is
set for both the input and the output data.

16/16
Input / output data (16 bytes each)
The maximum number of input and output bytes is 200 bytes each.
However a total number of 300 bytes (input + output) may not be exceed-
ed.
Default configuration: 2x 0x3F = 32 input and 32 output bytes
Attention:
The configured output data width must me at least 2 bytes (toggle and
length byte) greater than the longest used MIGRA control frame.
The configured input data width must me at least 2 bytes (toggle and
length byte) greater than the longest MIGRA response frame to be eval-
uated.
