Summary Each data point that is acquired through a ConfigProperty
object that represents arrays of elements must apply to a
single element within that array. This property applies
mainly to DataPoint objects that are acquired through
ConfigProperty objects.
Some ConfigProperty objects represent arrays of elements. In
this case, you need to create a separate data point to read
and write to each element in the array. When you create a
DataPoint object for such ConfigProperty objects with the
GetDataPoint method, you specify the index number of the
element to which the new DataPoint object should apply.
This property returns that index value. You can write to this
value if you want the DataPoint object to appl y to a different
element of the ConfigProperty array. These arrays are 0-
based, and the maximum index value is specified by the
Dimension property of the source ConfigProperty object. You
may find this procedure simpler than creating a separate
data point for each element in the array.
For DataPoint objects that were not acquired through
ConfigProperty objects, this property will be initialized to 0,
and you should not write to it.
Availability Local, full, lightweight, and independent clients. Note that
some objects containing this property are not available to
Independent clients.
