Description of the Software Modules and Parameters
4.5.2.3 Organization of the parameters in the data sets
Within the device there are seven separate memory areas for parameters that have the
"Data Set" attribute (DS 1 to DS 7).
In addition there is a "window" which represents the current active data set (DS 0). One
of these seven data sets is always selected active. By writing to Parameter
tive Data Set Number, Data Set 1, 2, 3, 4, 5, 6 or 7 can be selected to be active, hence it
is possible to switch between the data sets. In so doing, the window moves from DS 0 to
the memory area of the activated data set.
Example:
Data Set 3 is activated.
The "window" for the active data set addresses Data Set 3.
Figure 127:
Basically, only data from the active data set (DS 0) can be accessed via external option
modules or Fieldbuses.
