6.4.1.4 Layout of the data buffer for transferring ID-codes and results data
The data buffer in the interface module is divided into an input field and an output field. In the input field,
the partner controller stores the input control signals, the ID code and the IL data as Fieldbus master. In
the output field , the Fieldbus master receives the output control signals, the results data and the IL data.
All data (control signals, ID codes, tightening results) are located in a linear storage area at a location that
has been set by the configuration (see page 292). During project planning, the so-called master data file
(a GSD, EDS, or GSDML file, depending on the interface module) informs the partner controller on how
the data buffer is structured.
