Maintained push button

Toggle between two values by sending one value to the tag when
pressed, and a second value the next time the button is pressed and
released.

This button is useful for changing a setting within a machine or
process, but not for starting the machine or process.

Latched push button

Start a machine or process and remain set (latched) until the
process is completed, by sending a value to the tag when pressed,
and retaining this value until reset (unlatched) by the Handshake
connection.

Multistate push button

Cycle through a series of values. Each time the operator presses the
button, the value for the next state is sent to the tag. When the
button is in its last state, pressing it causes the button to change to
its first state and write out the first state value.

This button is useful when you want the operator to see and select
multiple options in sequence, using a single button. The button
shows the current state of a process or operation by showing a
different color, caption, or image to reflect the different states.

Interlocked push button

Use a group of buttons to send values to the same tag. When the
operator presses a button in the group, the button’s value is sent to
the tag, and the button remains highlighted as long as the tag value
is the same as the button’s value. Pressing a new button in the
group releases the other button and sends a new value to the tag.

You can also use a single Interlocked push button to send a value to
a tag.

Ramp button

Increase or decrease the value of a tag by a specified integer or
floating-point value.

Use two Ramp buttons together to create a raise/lower control.

Numeric input enable button

Enter a numeric value and write the value to a tag. You can also use
this object to ramp values.

Numeric input cursor point

RecipePlus button
