8.5.5.2 Rename Data Source
This operation allows batch renaming of data sources (the actual register, NV, or server
object name). All data sources which are mentioned in the selected entries will be
considered for renaming. If a particular source is actually renamed depends on the given
naming rules, as described in the previous section.
NOTE:
Renaming a data source does not reassign any references to that source, that is, all data
point objects which referenced the original data source will reference the same renamed
data source after this operation. To actually reassign data points to different data sources,
use the ‘reassign’ or ‘duplicate and reassign’ operations explained below.
8.5.5.3 Select Data Source
This operation is available if all selected entries reference the same data source. It allows
using the data point manager window to select a replacement data point, which must be of
compatible type (same type and direction as the original source).
8.5.5.4 Reassign Data Point
This operation allows reassigning a batch of entries to a new data source, based on the
currently referenced data point. Use the naming rules to construct the desired name of the
new data source from the name of the currently assigned data source.
This is most useful to remap all data points referencing data from one room to similar data
of another room, where the data source name contains the room number for easy remapping
(only the room number from the original name must be replaced by the number of the new
room to construct the name of the new data source).
NOTE:
In contrast to the ‘duplicate and reassign’ operation, this operation only attempts to
reassign the data points to other existing and compatible data sources. New sources will
not be created on the fly. Instead, the reassign operation fails if no compatible data source
can be found using the new name.
8.5.5.5 Duplicate and Reassign
This operation is similar to the normal reassign operation, only that the new name is not
used to search for an existing data source but the new name is used to create a copy of the
original data source and the selected item is reassigned to this copy.
The function keeps track of the copies it creates and ensures that each unique source is
copied only once. For example, if more than one selected entry references the same original
data source, one copy will be made of this source and all entries will be reassigned to this
copy. As a result, data points which referenced the same source before the duplicate
operation will reference the same source after the duplicate as well (only the references will
be to the copy of the original source).
8.5.5.6 Create Static NV / Server Object
This operation allows creating local data objects from remote data objects. Depending on
the network technology used by the device, it is possible to create static NVs which are
complementary to referenced external NVs or to create local server objects which are
complementary to an existing client mapping.
The operation works in the same way as duplicate and reassign, except that it creates new
data objects based on existing remote sources, instead of existing local sources.
