Latched push buttons lock in the on position, and must be unlocked by another button or
process to return to the off position. This type of button is useful for starting a machine or
process.
Multistate push buttons let an operator cycle through multiple options consecutively,
using a single button that displays the current state of a process or operation. Each state
can be represented by a different color, caption, or image.
Interlocked push buttons work in groups, and share the same tag. The buttons work
together like the preset station selector buttons on a car radio: pressing one button cancels
another. Although interlocked push buttons work as a group, you add them to the display
one at a time.
Ramp push buttons increase or decrease the value of a tag by either an integer or floating
point value. You can use two ramp buttons together to create an increase/decrease control,
for example for the speed of a motor.
Navigation push buttons can be configured to let the operator perform the following
actions: show previous display screen, show next display screen, and show a list of
previously shown screens.
For details about setting up a push button, click Help in the object’s Properties dialog box.
Creating button push buttons
Use the Button tool to create push buttons that work like standard Windows buttons.
You can assign FactoryTalk View commands to buttons, so they trigger actions when
pressed and released.
You can also attach different types of animation to a button, except for fill, rotation and
touch animation. For more information, see Chapter 18, Animating graphic objects.
Setting up button properties
In the Button Properties dialog box:
 In the General tab, specify general characteristics of the button including style, index
number, runtime focus highlight, and whether the cursor is captured when the button
is pressed.
 In the Action tab, set up how the button will behave when the user presses, holds, and
releases it at run time, and whether to show a confirmation dialog box before release
actions are performed.
Never use push buttons for emergency stops. Always hard-wire emergency stop buttons.
