Status Indicators Appendix A
If the OK status indicator is flashing red because of a nonrecoverable major fault,
the controller:
• initially displayed a solid red OK indicator.
• reset itself.
• cleared the project from its memory.
• set the OK indicator to flashing red.
• produced a major recoverable fault and generated a corresponding fault
code in the RSLogix 5000 project.
–
Fault code 60 means the CompactFlash card is not installed.
– Fault code 61 means the CompactFlash card is installed.
Follow these steps to recover from fault code 60 or 61.
1. Turn the controller keyswitch from PROG to RUN and back to PROG.
2. Go online with RSLogix 5000 and download the project.
3. Change to REM RUN or RUN mode.
If the issue persists, record the status of the OK and RS-232 indicators before
cycling power and contacting Rockwell Automation support.
Clear a Nonrecoverable Fault If the OK status indicator is solid red, follow these steps to clear the fault.
1. Cycle power.
2. Download the project.
3. Change to REM RUN or RUN mode.
If the issue persists, record the status of the OK and RS-232 indicators before
cycling power and contacting Rockwell Automation support.
Troubleshoot a
Nonresponsive Module Follow these steps to determine why a device may not be responding.
1. Verify that all I/O modules in your project are installed in the same order.
2. Verify that all devices have been updated to the latest major and minor
firmware revisions.
3. Use RSLogix 5000 software’s online help to determine which module is
not responding.
