When operating with EtherNet/IP, the network status indicator states
are described by the following table.
Table 11. Network Status Indicator: Ether Net/IP
Indicator
State
Summary
Requirement
Steady Off
Not Powered
No IP Address
The device is powered off, or is powered on
but with no IP address configured (Interface
Configuration attribute of the TCP/IP Interface
Object).
Flashing Green
No
Connections
An IP address is configured, but no CIP connections
are established, and an Exclusive Owner connection
has not timed out.
Steady Green
Connected
At least one CIP connection (any transport class)
is established, and an Exclusive Owner connection
(defined in Volume 1, Chapter 3) has not timed out.
Flashing Red
Connection
Time-out
An Exclusive Owner connection (defined in Volume
1, Chapter 3) for which this device is the target has
timed out. The network status indicator shall return
to steady green only when all timed out Exclusive
Owner connections are reestablished.
Devices that support a single Exclusive Owner
connection shall transition to steady green when
any subsequent Exclusive Owner connection is
established.
Devices that support multiple Exclusive Owner con-
nections shall retain the O->T connection path infor-
mation when an Exclusive Owner connection times
out. The Network LED shall transition from flashing
red to steady green only when all connections to
the previously timed-out O->T connection points are
reestablished.
Time-out of connections other than Exclusive Owner
connections shall not cause the indicator to flash
red.
The Flashing Red state applies to target connections
only. Originators and CIP Routers shall not enter
this state when an originated or routed CIP connec-
tion times out.
Steady Red
Duplicate IP
If the device has detected a non-recoverable major
fault, the module status indicator shall be steady
red.
Flashing Green
and Red
Self-test
While the device is performing its power up testing,
the module status indicator shall be flashing green
and red.
Note
: When a single indicator is used to represent multiple IP address interfaces the
state of any one interface shall be sufficient to modify the indicator state (per the
above behavior in the table):
•
Transition to flashing green when any one interface receives an IP address.
•
Transition to steady green when a CIP connection is established on any interface
(and Exclusive Owner is not timed out).
•
Transition to flashing red when an Exclusive Owner CIP connection times out on any
interface.
•
Transition to steady red when any of the interfaces detects an IP address conflict.
When operating with Modbus TCP, the Network Status indicator
states are described below.
Table 12. Network Status Indicator: Modbus TCP
Indicator State
Summary
Description
Steady Off
Not Powered, No IP
Address
Device is not powered, or is powered
with no IP address assigned.
Flashing Green
No Traffic
The device has an IP address, but no
Modbus TCP traffic detected.
Flashing Yellow
Modbus TCP Traffic
The device is receiving Modbus TCP
messages.
