Mod/Net Status LED
The Module/Network Status LED is a bi-colored (red/green) LED that provides status
information on DeviceNet communications. Table 3.6 on page 3-26 summarizes the
operation of the LED.
I/O Status LED
The I/O status LED is a bi-colored (red/green) LED that provides status information on
communications between the I/O module.
Table 3.6 LED Operation
For this state: MS/NS LED is: To indicate:
Powerup and Autobaud Flashes
green-red-off When power is connected, the LED will flash this pattern
one time. When waiting to detect the baud rate, the LED
will flash this pattern about every 3 seconds.
Not Powered/Not
On-line/Device is not on-line Off The device has not completed the Dup_MAC_ID test yet.
The device may not be powered.
Device Operational AND
On-line, Connected Green The device is operating in a normal condition and the
device is on-line with connections in the established state.
Device Operational AND
On-line, Not Connected or
Device On-line AND needs
commissioning Flashing Green The device is operating in a normal condition and the
device is on-line with no connections in the established
state. The device has passed the Dup_Mac_ID test, is
on-line, but has no established connections to other nodes.
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.
Critical Fault or Critical Link
Failure Red The device has an unrecoverable fault; may need replacing.
Failed communication device. The device has detected an
error that has rendered it incapable of communicating on
the network (Duplicate MAC ID, or Bus-off).
Communication Faulted and
Received and Identify Comm
Fault Request- Long Protocol Flashing Red &
Green A specific Communication Faulted device. The device has
detected a Network Access error and is in the
Communication Faulted state. The device has subsequently
received and accepted an Identify Communication Faulted
Request- Long Protocol message
Table 3.7 I/O Status LED
For This State: I/O Status
LED is: To indicate:
Off Off No power or All outputs in the inactive state. Configuration of I/O
modules good.
I/O Idle Flashing Green The DeviceNet network has caused the outputs to be in their idle state.
Idle/Program mode.
I/O Run Green Outputs are active.
I/O Recoverable Fault Flashing Red A connection controlling the outputs has timed out.
I/O Unrecoverable
Fault Red Configuration of I/O Module does not match saved configuration.
Power-up initialization of bus power failed.
CSUM Error at the module “X”.
Invalid Module ID “X”.
