Link Status Indicator
Steady
Off
Not pow-
ered,
unknown
link speed
If the device cannot deter-
mine link speed or power
is off, the network status
indicator shall be steady
off.
Red
Link speed =
10 Mbit
If the device is communi-
cating at 10 Mbit, the link
LED will be red..
Green Link speed =
100 Mbit
If the device is commu-
nicating at 100 Mbit, the
link LED will be green.
Activity Status Indicator
Flash-
ing
Green
Detects
activity
If the MAC detects activity, the
LED will be flashing green.
Red
Link
speed =
10Mbit
If the MAC detects a collision,
the LED will be red.

Requirement
Steady Off No power
If no power is supplied to the device,
the module status indicator shall be
steady off.
Steady
Green
Device
opera-
tional
If the device is operating correctly, the
module status indicator shall be steady
green.
Flashing
Green
Standby
If the device has not been configured,
the module status indicator shall be
flashing green.
Flashing
Red
Minor
fault
If the device has detected a recoverable
minor fault, the module status indica-
tor shall be flashing red.
NOTE: An incorrect or inconsistent
configuration would be considered a
minor fault.
Steady
Red
Major
fault
If the device has detected a non-recov-
erable major fault, the module status
indicator shall be steady red.
Flashing
Green /
Red
Self-test
While the device is performing its pow-
er up testing, the module status indica-
tor shall be flashing green / red.

no IP ad-
dress
If the device does not have an IP ad-
dress (or is powered off), the network
status indicator shall be steady off.
Flashing
Green
No con-
nections
If the device has no established connec-
tions, but has obtained an IP address,
the network status indicator shall be
flashing green.
Steady
Green
Con-
nected
If the device has at least one estab-
lished connection (even to the Message
Router), the network status indicator
shall be steady green.
Flashing
Red
Connec-
tion
timeout
If one or more of the connections in
which this device is the target has
timed out, the network status indicator
shall be flashing red. This shall be left
only if all timed out connections are re-
established or if the device is reset.
Steady
Red
Duplicate
IP
If the device has detected that its IP
address is already in use, the network
status indicator shall be steady red.
Flashing
Green /
Red
Self-test
While the device is performing its
power up testing, the network status
indicator shall be flashing green / red.
Using DeviceNet™
Communications To/From Third Party Device:
Like EtherNet/IP when using the DeviceNet™ pro-
tocol, there are two methods used in communicating,
implicitly (See:
) and explicit-
ly. Because DeviceNet and Ethernet/IP both use CIP,
the communications examples discussed above apply
here as well. To acquire a better understanding of
DeviceNet communications substitute DeviceNet for
EtherNet/IP and review the section entitled "
EtherNet/IP, Communications To/From a Third Party
".
DevceNet Indicator LED's
The RMA has four indicator LEDs on the top of the
module, two of which (rear two) are used for Devi-
ceNet (Module Status and Network Status). The char-
acteristics of these two LEDs is established by the
Open DeviceNet Vendors Association (ODVA,
)
