8.6 EtherNet/IP Scanner (Master)
For the EtherNet/IP Scanner 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 V2.6.
LED
Color

Meaning
Duo-LED red/green
(green)
On
Device operational
: The device is operating correctly.
(green)
Flashing
(1 Hz)
Standby
: The device has not been configured.
(red/green)
Flashing
(1 Hz)
Self-test
: The device is performing its power up testing.
(red)
Flashing
(1 Hz)
Minor fault
: The device has detected a recoverable minor fault. E. g. an
incorrect or inconsistent configuration can be considered as a minor fault.
(red)
On
Major fault
: The device has detected a non-recoverable major fault.
MS
(Module
status)
General
name:
COM 0
(Off)
Off
No power
: The power supply to the device is missing.
Duo-LED red/green
(green)
On
Connected
: The device has at least one established connection (even to the
Message Router).
(green)
Flashing
(1 Hz)
No connections
: The device has no established connections, but has
obtained an IP address.
(red/green)
Flashing
(1 Hz)
Self-test
: The device is performing its power up testing.
(red)
Flashing
(1 Hz)
Connection timeout
: One or more of the connections in which this device is
the target have timed out. This status will be finished only if all timed out
connections are reestablished or if the device is reset.
(red)
On
Duplicate IP
: The device has detected that its IP address is already in use.
NS
(Network-
status)
General
name::
COM 1
(Off)
Off
Not powered, no IP address
: The device does not have an IP address (or is
powered off).
LED green
(green)
On
The device is linked to the Ethernet.
LINK
Ch0 & Ch1
(Off)
Off
The device has no link to the Ethernet.
LED yellow
(yellow)
Flickering
(load de-
pendant)
The device sends/receives Ethernet frames.
ACT
Ch0 & Ch1
(Off)
Off
The device does not send/receive Ethernet frames.

LED state
Definition
On
The indicator is constantly on.
Off
The indicator is constantly off.
Flashing (1 Hz)
The indicator turns on and off with a frequency of 1 Hz:
“on” for 500 ms, followed by “off” for 500 ms.
Flickering
(load
dependant)
The indicator turns on and off with a frequency of approximately 10 Hz to indicate high Ethernet
activity: on for approximately 50 ms, followed by off for 50 ms. The indicator turns on and off in
irregular intervals to indicate low Ethernet activity.
