Diagnosis with LEDs
26/55
5.4
EtherNet/IP Adapter
For the
protocol, the communication LEDs
MS
and
NS
as well as the Ethernet LEDs
LINK
and
ACT
can assume the states
described below. This description is valid from stack version V2.7 (V2) or
from V3.0.
LED
Color
State
Meaning
MS
(module status)
Duo LED red/green
(green)
On
Device operational:
The device is operating correctly.
(green)
Flashing (1 Hz)
Standby:
The device has not been configured.
(green/red/
green)
Flashing
green/red/
green
Self-test:
The device is performing its power-up testing.
The module status indicator test sequence occurs before the
network status indicator test sequence, according to the
following sequence:
·
Network status LED off.
·
Module status LED turns green for approximately 250 ms,
turns red for approximately 250 ms, and again turns green
(and holds that state until the power-up test has completed).
·
Network status LED turns green for approximately 250 ms,
turns red for approximately 250 ms, and then turns off (and
holds that state until the power-up test has completed).
(red)
Flashing (1 Hz)
Major recoverable fault:
The device has detected a major
recoverable fault. E.g., an incorrect or inconsistent
configuration can be considered a major recoverable fault.
(red)
On
Major unrecoverable fault:
The device has detected a major
unrecoverable fault.
(off)
Off
No power:
The device is powered off.
NS
(Network status)
Duo LED red/green
(green)
On
Connected:
An IP address is configured, at least one CIP
connection (any transport class) is established, and an
Exclusive Owner connection has not timed out.
(green)
Flashing (1 Hz)
No connections:
An
connections are established, and an Exclusive Owner
connection has not timed out.
(green/red/off)
Flashing
green/red/off
Self-test:
The device is performing its power-up testing. Refer
to description for module status LED self-test.
(red)
Flashing (1 Hz)
Connection timeout:
An IP address is configured, and an
Exclusive Owner connection for which this device is the target
has timed out.
The network status indicator returns to steady green only
when all timed out Exclusive Owner connections are
reestablished.
(red)
On
Duplicate IP:
The device has detected that its IP address is
already in use.
(off)
(Off)
Not powered, no IP address:
The device does not have an
IP address (or is powered off).
LINK
LED green
(green)
On
The device is linked to the Ethernet.
(off)
Off
The device has no link to the Ethernet.
