Indication

Not powered/not on-line

Off

Device is not on-line. Device has not completed the Dup MAC ID test. Device may not
be powered.

Device operational and on-
line, connected

Solid green

Device is operating in a normal condition and is on-line with connections in the
established state. For Group 2 only, the device is allocated to a master. For a UCMM
capable device it means that the device has one or more established connections.

Device operational and on-
line, not connected, or
device on-line and needs
commissioning

Flashing green

Device is on-line with no connections in the established state. Device has passed the
Dup MAC ID test, is on-line, but has no established connections to other nodes. For a
Group 2 Only device, the device is not allocated to a master. For a UCMM capable
device it means that the device has no established connections. Configuration
missing, incomplete or incorrect.

Minor fault and/or
connection time-out

Flashing red

Recoverable fault and/or one or more I/O connections are in the timed-out state.
Recoverable faults include:

Failed Power Supply power-up test.

Faulted 24V DC, Out2, Out3.

Critical fault or critical link
failure

Solid red

Device has an unrecoverable fault and may need replacing. Device has detected an
error that has rendered it incapable of communication on the network (Dup MAC
failure or Bus Off).

Communication faulted and
received an identify comm
fault request - long protocol

Flashing red and
green

A specific communcation faulted device. the device has detected a network access
error and is in the communcation faulted state. The device has subsequently received
and accepted an identify communcation faulted request - long protocol message.
