8.7.1 Formats of the data points
The different formats of the data points are described in this section. This includes the
description of the Motorola format used, e.g. "int" and "unsigned int", as well as, above all,
the description of special formats. A special format is, for example, the binary breakdown of
the data point that specifies the last tripping operation.
All available data points and the data set in which they are transferred over PROFIBUS have
been described on the preceding pages. In the "Format" column, an explanation is given of
which data type is referred to and how this content is to be interpreted. A distinction must be
made here between generally valid formats and special formats that are usually binary
coded.
