Digital inputs
LEDs display the status of each of the eight DIOs when used as
inputs. If the LED is on, it indicates that the input is on.
Digital outputs
When the DIOs are used as outputs, the LEDs display the status
of each of the digital outputs. If an LED is on, it indicates that the
output is on. The LEDs also indicate if the output is in a fail-safe
state by flashing at different rates. If an LED is mostly on (long
on) it indicates that the fail-safe state shown on the Digital Output
Configuration page is on. If an LED is mostly off (long off) it indicates
that the fail-safe state shown on the Digital Output Configuration
page is OFF. See “Fail-safe blocks” on
page 15
for details.
Analog inputs
There are two LEDs for each differential analog input. The first LED
(+) is used to indicate that the analog input is reading a current
(mA). The second LED (–) indicates that the input is reading voltage.
Each of the analog input LEDs will come on when there is a signal
present at the analog input.
Analog outputs
Each analog output has an LED in series that indicates the output
current by increasing or decreasing the intensity of the LED. For
example, at 4 mA the LED appears dimmed, and at 20 mA, the LED
appears bright.
Ethernet LEDs
On the end plate, the Ethernet socket incorporates two LEDs that
indicate the Ethernet status.
•
100 M
—Green LED indicates presence of a 100-Mbps Ethernet
connection. With a 10-Mbps connection, the LED is off.
•
LINK
—Orange indicates an Ethernet connection. The LED briefly
flashes with activity.
