The following objects can be displayed on both the keypad terminal and
the touch screen terminal:
Momentary Push Button (Normally Open) turns on (sets to 1) a PLC
input control bit, as long as the button is held.
Momentary Push Button (Normally Closed) resets a PLC input
control bit that is normally set to 1. This bit stays off as long as the
button is pressed.
Latched Input Push Button turns on a PLC input control bit and holds
the bit on until the PanelView 1200 terminal sees a PLC output bit
(handshake bit) turn on.
Maintained Push Button turns on a specific PLC input control bit until
the button is pressed a second time.
Interlocked Push Buttons are several push buttons functioning as a
group. When you press one of the buttons, it cancels the other buttons
and makes the selection. The PLC controller is informed—via a
common PLC input address—which button in the group is the currently
selected option.
Control List Selector with Enter contains a vertical list of operator
choices. An operator can use the object's Up Cursor and Down Cursor
buttons to move an arrow through the available selections. The selection
is sent to the PLC controller only when the Enter button is pressed.
Control List Selector without Enter contains a vertical list of choices.
The operator uses the object's Up Cursor and Down Cursor buttons to
move through the available selections. The current selection is
automatically sent to the PLC controller via the object's PLC input
control address.
"Goto Screen" Button allows the operator to switch to an assigned
screen.
"Return To Previous Screen" Button switches back to the previous
screen.
Screen List Selector allows an operator to choose a screen from a list.
Multistate Indicator is a display area with up to sixteen different
display states, each with a unique combination of text, colors and
attributes. The value in the PLC address determines which state is
displayed.
