Basically the items are selected in the 'Provider Data Items' field and either via a
double-click or via button > (single) or >> (all) can be inserted in the Selected Data
Items field in the right part of the dialog. Vice versa selected items correspondingly can
be removed by the < and << buttons..
In the structured view concerning function block and data types there is the possibility
to reduce the selection on particular member variables. Proceed as follows:
In the 'Provider Data Items' field under node 'Application' select the desired variables. If
instances of function blocks or data types are involved, automatically all member
variables of those POUs will be published. If this is not desired, the finally to be
published items can be reduced to particular POU members by selecting those
explicitly under node 'Datatypes'.
This configured selection will immediately be usable by the application.
Access rights:
By default each item is 'readable and writable', see the AccessRights column. To modify
the access right to 'read only', click in the respective AccessRights field to get into edit
mode and then click again to toggle the access right symbol.
Symbol 'read and write':
Symbol 'read only':
The meaning of the access rights of a data item, if option Update by default is
activated in the eponymous column:
read: the item will be updated in the current application if it has changed in the data
source
write: the item will be updated in the data source if it has changed in the current
application
Note: By default the selected data items 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 (Currently
please contact your software supplier in this case).
