Automatic Diagnostics overview

By default, new projects contain an

Automatic Diagnostics

screen with an Automatic Diagnostics table, and an

Automatic Diagnostics History

screen with an Automatic Diagnostics History table. These screens exist in the

Predefined Screens

folder of the

Project Explorer

. New projects have shortcuts to the predefined

Automatic Diagnostics

and

Automatic Diagnostics History

screens.

You can create your own diagnostics screens by using

Automatic Diagnostics

and

Automatic Diagnostics History

graphic elements from the Toolbox.

Automatic Diagnostics of hardware configured in your Logix controllers automatically appear on the Automatic Diagnostics and Automatic Diagnostics History. No additional configuration in

View Designer

is needed.

Rockwell Automation

recommends that an automatic diagnostics table be the only graphic element on a screen.

Available operations depend on the

Automatic Diagnostics

screen:

In

View Designer

, automatic diagnostics tables contain sample data representative of the data an automatic diagnostics table may display. The sample data inserts data of average length into the default columns in the automatic diagnostics table. Sample data appears in order to configure the automatic diagnostics table. Use sample data to determine and change column width, font, font size, and padding around content. Changes to font and padding properties do not appear in the

pane of an automatic diagnostics table.

Automatic Diagnostics tables scale to the size of the target HMI device. When you download a project to a different size HMI device, default automatic diagnostics tables may not provide the best results on the new HMI device screen.

Large automatic diagnostics tables are designed for ten-inch or larger HMI device screens, while medium automatic diagnostics tables are designed for six- to nine-inch HMI device screens. The size of an automatic diagnostics table does not affect the number of automatic diagnostics the table displays. When you download a project to an HMI of a different size,

Rockwell Automation

recommends replacing the automatic diagnostics tables in the project. Open the existing automatic diagnostics screens, delete the existing automatic diagnostics tables from the screens, and add the correct size automatic diagnostics tables for the new HMI device.
