PROFIBUS-DP – Parameterization in DIGSI
6.3.3 Parameterization of scaling values in DIGSI
Scaling index
6-10
The "Object properties" dialog window contains for measured values -
besides the property sheet "Protocol info source" or "Protocol info
destination" – an additional property sheet titled "Measured value
destination".
Figure 6-3
Scaling settings of a measured value
The scaling values assigned to the measured values per default are
described in the bus mapping documents of the SIPROTEC device
types (ref. to page i).
The change of the scaling and with that customization to the installation-
specific operating values is made by selection of one scaling indices in
the "Object properties" dialog window of the measured value.
A predefined scaling possibility (settings of Type, Scaling factor and
Zero offset) is summarized using a scaling index.

If after change of the scaling a bus specific parameter is changed
(e.g PROFIBUS-DP slave address, ref. to chap. 1), then all scalings
are reset to their defaults according to the bus mapping documents
(ref. to page i) again.
