Removing objects from the tab sequence
By default, you can use the Tab and arrow keys to navigate to objects that can have input
focus in a graphic display.
You can also turn off key navigation for objects that take input focus, except for push
buttons, recipe objects, input objects, and HMI tag alarm summaries.
When an object’s key navigation is turned off, an operator can still select the object using
a mouse or touch screen, if one is available.
Turning off key navigation
To turn off key navigation, use one of these methods:
 For display list and control list selectors, open the object’s Properties dialog box, click
the General tab, and then clear the check box, Key navigation.
 For ActiveX objects, trends, and Alarm and Event objects, open the object’s
Properties dialog box, click the Common tab, and then clear the check box, Key
navigation.
 In the Property Panel for the object, click the Properties tab, and then set the
KeyNavigation property to False.
Creating the different types of push buttons
Push buttons start or stop processes or actions and change tag values. You can create the
following types of push buttons, depending on the needs of the application:
Button objects can change tag values, or run FactoryTalk View commands.
Momentary push buttons change a tag to one value when the button is pressed, and
another value when the button is released.
Momentary push buttons work like the Pulse button on a food processor, but with an
indicator light to signal whether the motor is running or stopped. The machine is on only
while the button is held down. When the button is released, the machine turns off.
Momentary push buttons are useful for jogging a motor, and they can be set up to start and
stop a machine or process.
Maintained push buttons switch between two values.
This type of button is useful for changing a setting within a machine or process, but not
for starting the machine or process. For example, use the maintained push button for
changing modes, such as Auto to Manual, or Metric to Imperial.
