Assigning Data Items in Data Lists

An assignment of data items can be made by simply selecting a data item in the required column. After assigning data items this way, other Data Lists in the project are automatically updated accordingly.

The procedure below applies to both the Data List of the controller and the Safety PLC. However, safety-related variables can only be assigned to process data items of safety-related devices.

For selecting a data item in a table field, the Role Picker is available which can be used as follows.

Note
In Data Lists, Port Lists and variables tables, the selection in drop-down lists is done with a single-click, not with a double-click.

  1. In the table, left-click into the field where you want to assign a data item and which is showing the text 'Select ... here' or move the table cursor using the arrow keys or <Tab>/<Shift>+<Tab> to this table field and press <Enter>.

    The Role Picker appears. It is divided into a tree on the left and data items on the right. The Role Picker only provides data items for selection which match the data type for the assignment to be done.

  2. Select a folder in the tree on the left and then the data item on the right by clicking it or pressing the <Enter> key.

Note
The Role Picker retains your last selection as long as the editor has not been closed.

Use the following keys to navigate in the Role Picker.

Press the shortcut ... ... to ...
<Tab>/<Shift> + <Tab>switch between the folders on the left and the entries on the right.
<ArrowDown>/<ArrowUp>move the cursor down/up.
<Enter>
(focus on the right side)		select the currently marked entry, close the selection control and apply the entry to the table field.
<ArrowRight>/<ArrowLeft>
(focus on the left side)		expand/collapse the currently marked folder on the left.
