60 Use Data Views to Access Controller Data
Sort Data Views
You can sort data views alphabetically by name, filename, or
description, or numerically by number of tags.
1. Click a column name.
The first click sorts in ascending order.
2. Click again to sort in descending order.
An arrow next to the column name shows the direction of the
current sort.
You can also sort the tags within a data view by clicking on the
slot, tag name, data type, display as, value, or access headings in
the column title.
Interface with the Logix Controller
When you request to display a data view, the module establishes one
connection to the target controller. Tag values are read and written
over this connection. After the module retrieves the data view or
updates the data view, the module closes the connection.
If someone changes tag names in the target controller and does not
update the tags in the data view, the data view will display an error
message indicating that the tag was not available.
Click a column heading
to sort the column.
