13.5.4 Use data sources in visualizations
All visualizations assigned to an application can use all data sources which are also
assigned to that application.
The data items (variables) of the data source can be used in the properties
configuration of a visualization. They might be entered via the Input Assistant or "List
Components" function, but also manually. If entered manually, the complete identifier
path must be typed in according to syntax: <name of data source device>.<POU
name>.<variable name>.
Example:
See below the Properties dialog for a visualization element. As text variable variable
"iCount" from a defined data source is used. This data source is "Device2", containing
application "App1" with POU "prg1".

Note: Bit accesses used in visualizations will only work over a Data Server
connection if the bit index is defined literally (and not by a defined constant).
Note: The Diagnosis Visualization - because it is only designated to inspect the
current application - in contrast to the Target-Visualization will not monitor the
current values of variables which are provided via the Data Server from another data
source! For those just the initial values will be displayed.
Note: By default the selected data items always will be updated only in the currently
active visualization. If an item is also used in another POU of the application it has to
be activated explicitly by using the functions of the Data Server Interface.
