Understanding the Features

Display and Setpoint Operations
The OP-414 has six LEDs with a label for each one. Each LED (with its label) refers
to a user-defined field point. These field points are actually memory locations in the
PLC where data is stored. You can make a field point a read only location--in which
case, we refer to it as
display data
. Or you can designate a field point to store
setpoint data
--in which case, the field point is a read/write location. The panel
allows you to either read the display data or read and write the setpoint data. When
an LED is on, the corresponding field point (in the PLC) is displayed on the panel.
Look at the illustrated example below.
Pressing the <SELECT> key scrolls through the field points, turning the LED on
and displaying the data from the PLC. If you move to a label whose field point
has been configured as
setpoint data
, then you can use the UP or DOWN
ARROWS to change the value shown in the window. However, the UP or DOWN
ARROWS have no effect on field points that have been configured as
display
data
.
