Appendix E Troubleshooting
• Non-recoverable – A non-recoverable fault requires the controller to be
power cycled before clearing the fault. After the controller has been power
cycled or reset, check the fault log in the Diagnostic page of the Connected
Components Workbench software, then clear the fault. The fault LED is
solid red when a non-recoverable fault occurs.
List of Error Codes for Micro800 controllers
Error Code Fault Type Description Recommended Action
0xF000 Recoverable The controller was unexpectedly reset due to a
noisy environment or an internal hardware
failure.
If the system variable
_SYSVA_USER_DATA_LOST is set, the controller
is able to recover the user program but the user
data is cleared. If not, the Micro800 controller
program is cleared.
Perform one of the following:
• See Corrective Actions for Recoverable Faults
on page 313.
• Check wiring to eliminate any noise, refer to Wiring Requirements
and Recommendation on page 41.
0xF001 Recoverable The controller program has been cleared. This
happened because:
• a power-down occurred during program
download or data transfer from the memory
module
• the cable was removed from the controller
during program download.
• the RAM integrity test failed.
Perform one of the following:
• See Corrective Actions for Recoverable Faults on page 313.
• Transfer the program using the memory module restore utility.
0xF002 Non-
recoverable
The controller hardware watchdog was activated.
The controller hardware watchdog timeout
happens if program scan is more than three
seconds.
If the system variable
_SYSVA_USER_DATA_LOST is set, the controller
is able to recover the user program but the user
data is cleared. If not, the Micro800 controller
program is cleared.
See Corrective Actions for Non-recoverable Faults on page 313.
0xF003 Recoverable One of the following occurred:
• The memory module hardware faulted.
• The memory module connection faulted.
• The memory module was incompatible with
the Micro800 controller’s firmware revision.
Perform one of the following:
• Remove the memory module and plug it in again.
• Obtain a new memory module.
• See Corrective Actions for Recoverable Faults
on page 313.
• Upgrade the Micro800 controller’s firmware revision to be
compatible with the memory module. For more information on
firmware revision compatibility, go to
http://www.rockwellautomation.com/support/firmware.html
0xF004 Recoverable A failure occurred during the memory module
data transfer.
Perform one of the following:
• See Corrective Actions for Recoverable Faults
on page 313.
• Attempt the data transfer again. If the error persists, replace the
memory module.
• For Embedded RTC failure, restart the controller.
0xF005 Recoverable The user program failed an integrity check while
the Micro800 controller was in Run mode.
Perform one of the following:
• See Corrective Actions for Recoverable Faults
on page 313.
• Refer to the Wire Your Controller on page 41.
