Major fault • RSLogix 5
download in
progress
• Run-time error
During RSLogix 5 download, this is normal
operation - wait for download to
complete.
If not during RSLogix 5 download:
• Check major fault bit in status file
(S:11) for error definition
• Clear fault, correct problem, and return
to run mode
Alternating
Red and
Green
Processor in
FLASH-memory
programming mode
Normal operation if
processor's FLASH
memory is being
reprogrammed
No action required - allow flash update to
complete
Red
(steady) Power cycle with
problem battery
Battery is low,
disconnected or not
installed
Properly replace or install battery (see

Red
(steady) Fault with memory loss • New processor
• Invalid ControlNet
network address
• Processor has failed
internal diagnostics
• Use programming software to clear and
initialize memory
• Verify that ControlNet address switch is
not set to 0
• Install battery (to preserve failure
diagnostics), then power down, reseat
processor and power up; then reload
your program. If you are unable to
reload your program, replace the
processor. If you are able to reload your
program and fault persists, contact
Technical Support at 440.646.6800 to
diagnose the problem.
