Requirement
Power to the device is off or is on but no IP address
has been configured (Interface Configuration attribute
of the TCP/IP Interface Object).
An IP address has been configured but no CIP
(common industrial protocol) connections
been established, and an exclusive owner
connection Note 2 has not reached time-out.
An IP address has been configured, at least one CIP
connection (in any transport class) has been
established, and an exclusive owner connection has
not reached time-out.
owner connection for which this device is the target
has reached time-out. The network state indicator shall
only return to being steadily green when all timed-out
exclusive owner connections are re-established.
In devices that support a single exclusive owner
connection, a transition to being steadily green is to
proceed when any subsequent exclusive owner
connection is established.
Devices that support multiple exclusive owner
connections shall retain the O->T (Originator to Target)
connection path information when an exclusive owner
connection reaches time-out. The network status
indicator shall make the transition from flashing red to
steadily green only when all connections to previously
timed-out O->T connection points have been re-
established.
Time-out of connections other than exclusive owner
connections are not to cause the indicator to flash red.
The flashing red state applies to target connections
only. Originators and CIP routers are not to cause the
LED to enter this state.
While the device is performing its power up testing, the
network status indicator shall perform a test sequence
as described in Table 5.3.
