Latched push button

Start a machine or process. The button remains set (latched) until the process is
complete. For example, use this button to start a bag filling machine. When the
process is complete (the bag is full), the button is reset (unlatched) by the
Handshake connection. For details, see page 21-22.

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 changes the button to its first state and writes 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
an operation by showing a different color, caption, or image to reflect the
different states. For details, see page 21-24.

Interlocked push button

Use a group of buttons to send values to the same tag. When the operator
presses one 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 another button in the group releases the first button, and sends a
new value to the tag. For details, see page 21-25.

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. For example, use two Ramp buttons together to create a raise/lower
control. For details, see page 21-27.

Control list selector

Select from a list of states for a process or operation. The list is highlighted to
show the current state, and the operator can scroll through the list to select a
different state. The value assigned to the selected state is written to the tag. For
details, see page 21-49.

Piloted control list selector

Select from a list of states for a process or operation. The list is highlighted to
show the current state, and the operator or a remote device such as a
programmable controller can scroll through the list to select a different state.
For details, see page 21-51.

Drawing object with
horizontal or vertical slider
animation

Set the value of a tag by dragging the slider object. The pixel position of the
slider is translated into a value that is written to the tag. If the value of the tag is
changed at the data source, the position of the slider changes to reflect this. For
information about animation, see Chapter 22.

ActiveX object

Change tag values using a third-party object connected to an analog, digital, or
string tag, including both HMI and data server tags. When the object’s property
value changes, the new value is written to the associated tag. For details, see
page 20-22.
