Table 48 - Module Status Indicator - Compact 5000 I/O Digital Modules
Indicator 
State
Description Recommended Action
Off The module is not powered. None if your application does not use 
the module
If your application uses the module and it is 
expected to be operating, complete 
the following:
• Confirm that the system is powered. 
• Confirm that the module is installed properly. 
Steady green The module has a connection to the owner-
controller and is operating normally.
None
Flashing 
green
One of the following:
• The module does not have a connection to 
the controller. A connection can result from 
missing, incomplete, or incorrect 
module configuration.
• Compact 5000 I/O Safety Modules only - A 
connection can be established with the 
controller, but the Validator has not 
completed an initial Time Coordination 
exchange.
Troubleshoot your Logix Designer application to 
determine what is preventing a connection from 
the module to the controller and correct the 
issue.
Steady red The module experienced a nonrecoverable fault. Complete the following actions:
1. Cycle power to the module.
2. If the status indicator remains in the steady 
red state, replace the module.
Flashing red One of the following conditions exists:
• A module firmware update is in progress.
• A module firmware update attempt failed.
• The device has experienced a 
recoverable fault. 
• A connection to the module has timed out.
Complete one of the following:
• Let the firmware update progress complete.
• Reattempt a firmware update after one fails.
• Use the Logix Designer application to 
determine the cause of the module fault.
The Connection and Module Info categories 
of the modules configuration indicate the 
fault type.
To clear a recoverable fault, complete one of 
the following:
– Cycle module power.
– Click Reset Module in the Logix Designer 
application project via the Module Info 
category of the Module Properties dialog 
box.
If the fault does not clear after you cycle 
power and click Reset Module, contact 
Rockwell Automation® Technical Support.
• Use the Logix Designer application to 
determine if a connection has timed out. The 
Connection category in the Module 
Properties for the module indicates the 
module state, including if a connection has 
timed out.
If a connection has timed out, determine the 
cause and correct it. For example, a cable 
failure can cause a connection timeout.

green
Compact 5000 I/O Safety Modules only - The 
UNID needs to be commissioned in the module.
Commission the UNID in the module.
