4-10 Troubleshooting Status Indicators
Troubleshooting for
DeviceNet Drives
DeviceNet Module Status LED
Use the table below for troubleshooting the DeviceNet Module Status
LED on your Ultra3000 (2098-DSD-xxx-DN, -xxxX-DN, -HVxxx-DN, or
-HVxxxX-DN).
DeviceNet Network Status LED
Use the table below for troubleshooting the DeviceNet Network Status
LED on your Ultra3000 (2098-DSD-xxx-DN, -xxxX-DN, -HVxxx-DN, or
-HVxxxX-DN).
If the Module
Status LED is:
Status is: Potential Cause is: Possible Resolution is:
Off Not powered No power There is no power going to the device.
Steady-Green Operational Normal operation Normal operation - no action needed.
Flashing-Green
Device is in
stand-by
Processing or waiting
for input
Normal operation - no action needed.
Flashing-Red Recoverable fault Not operational Power cycle or reset the drive.
Steady-Red
Unrecoverable
fault
Drive problem
1. Check drive for power-up error.
2. Replace drive.
Flashing-Red/
Green
Self testing Self-test in progress The device is in self test, wait.
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
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.
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.
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.
