Module Status Indicator
Tab le 23  describes the Module Status indicator on FLEX 5000 I/O modules.
Table 23 - Module Status Indicator - FLEX 5000 Digital I/O Modules
Indicator State Description Recommended Action
Off The module is not powered. Complete the following actions:
1. Confirm that the system is powered.
2. 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 conditions exist:
• The module has powered up successfully.
• The module is OK, but it does not have a connection.
No connection can result from missing, incomplete, or incorrect 
module configuration.
For safety modules only - A connection can be established with the 
controller, but initial time coordination exchange is not complete.
Connection to an output module is in the idle state.
Complete the following actions:
• Troubleshoot your Logix Designer application to determine what is 
preventing a connection from the module to the controller and correct 
the issue.
• Confirm that the system conditions require the controller to be in 
Remote Run mode or Run mode, transition the controller to one of those 
modes.
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 exist:
• 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 project via the Module Info 
category of the Module Properties dialog box.
If the fault does not clear after cycling power and clicking 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.
Red/green (railroad) For safety modules only - This pattern indicates that a UNID for the 
safety device needs to be configured.
None
