Normal Operation
The POWER and RUN indicators are on. If a force condition is active, the
FORCE indicator turns on and remains on until all forces are removed.
Error Codes
This section lists possible error codes for your controller, as well as
recommended actions for recovery. Information about the fault is stored in a
fault log, which can be accessed from the Diagnostics page in Connected
Components Workbench software. The fault log contains brief information
about the last fault, and detailed information about the last 10 non-recoverable
faults that occurred.
If an error persists after performing the recommended action, contact your
local Rockwell Automation technical support representative. For contact
information, go to
rok.auto/support .
Fault Types
There are two basic types of faults that can occur:
• Recoverable – A recoverable fault can be cleared without having to power
cycle the controller. The fault LED flashes red when a recoverable fault
occurs.
• 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.
Table 56 - 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 270 .
• Check wiring to eliminate any noise.
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 270 .
• 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 3 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.
