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.
