Set Bit Cursor Point consists of a bit and a cursor character. This
object is used to "point" to a screen character. Several set bit cursor
points can be in the same screen. Each one can have a different
(user-defined) pointer; only the current pointer is visible and blinking.
The current cursor point's input bit is always on, so the PLC controller
always "knows" the current selection.
Both the set bit and numeric input cursor points can be used on the same
screen.
The following objects can be displayed only on a touch screen terminal:
Keypad Screen Selector allows an operator to display a screen by
entering the screen number. The selector is available in large and small
sizes.
Numeric Keypad is used to send a value to the PLC controller. A PLC
input address is assigned to each Numeric Keypad; the value that the
operator enters is stored at this address. The keypad is available in large
and small sizes.
The Information and Alarm Windows can pop up on the screen at any time
to display important information:
Information Window displays a message when triggered by the PLC
controller. The window remains until the operator presses the Clear
button, or until the PLC controller clears it. There can be as many as
496 different messages for the Information Window.
Alarm Window is similar to the Information Window but with many
additional features. Each message can be configured to sound the audio
indicator (beeper), trip the alarm relay or print a message on a printer.
Alarms are time and date stamped and listed in the order they occur. The
operator can acknowledge the alarm, clear the display, silence the alarm,
view the Alarm History Screen, or view the Alarm Status Screen. There
can be as many as 496 different messages for the Alarm Window.
