5-2 Troubleshooting DeviceNet Drives
Module Status LED
Use the table below for troubleshooting the Module Status LED on the
DeviceNet interface to the Ultra5000.
Network Status LED
Use the table below for troubleshooting the Network Status LED on
the DeviceNet interface to the Ultra5000.
If the Module
Status LED is:
Status is: Potential Cause is: Possible Resolution is:
Off Not powered No power Provide power to the device.
Flashing-red Recoverable
fault
Not operational Power cycle or reset the drive.
Steady-red Unrecoverable
fault
Drive problem Check drive for power-up error.
Replace drive.
Flashing-red/
green
Self testing Self-test or
initialization in
progress
The DeviceNet interface is being initialized or in self-test
— wait.
Flashing-green Device is in
stand-by
Processing or waiting
for input
Normal operation - no action needed.
Steady-green Operational Normal operation Normal operation - no action needed.
If the Network
Status LED is:
Status is: Potential Cause is: Possible Resolution is:
Off Not powered
Not on-line
No power going to the
device.
Failed Duplicate MAC ID
check.
No network (24V) power
Network miswired.
1. Check the Module Status LED to verify that the drive is powered.
2. Check that one or more nodes are communicating on the
network.
3. Check that at least one other node on the network is operational
and the data rate is the same as the drive.
4. Provide network (24V) power.
5. Check that the DeviceNet connector is correctly wired.
Flashing-red On-line
Time-out
I/O connection timed out. 1. Re-initiate I/O messaging by the master controller.
2. Reduce traffic or errors on the network so that messages can get
through within the necessary time frame.
Steady-red Network failure Failed Duplicate MAC ID
check.
Bus off.
1. Ensure that all nodes have unique addresses.
2. If all node addresses are unique, examine network for correct
media installation.
3. Ensure that all nodes have the same Data Rate.
Flashing-green On-line
Not connected
Passed Duplicate MAC ID
check.
No connection established.
No action is needed. The LED is flashing to signify that there are no
open communication connections between the drive and any other
device. Any connection (I/O or explicit message) made to the drive
over DeviceNet will cause the LED to stop flashing and remain
Steady-ON for the duration of any open connection.
Steady-green On-line
Connected
One or more connections
established.
No action needed. This condition is normal.
