AN-T80020 Diagnostics Procedure
Issue 12 Feb 11 AN-T80020 68
0x8000 Series Codes (General non-resettable)
All faults above 8000 cannot be reset using the processor’s Reset pushbutton. They are either
indicating a failed startup or a fault found in the operational logic circuits through background testing.
Codes 0x8400 to 0x8402
Modules: 8480 These indicate faults in programming the host interface ASIC. The
module will fail to start. Return the module for repair.
The faults are reported by all other modules as 0x0400, 0x0401 or
0x0402.
FIA_INVALID_IMAGE
0x8500
Modules:All Validates the field interface adapter code file prior to and during
loading. Detects flash memory fault or missing file. The slice will not
boot. Return the module for repair.
FIA_INVALID_IMAGE_CRC
0x8501
Modules:All Validates the field interface adapter code file prior to loading. Detects
flash memory fault or corrupted file. The slice will not boot. Return the
module for repair.
APP_MEMORY_FAULT
0x8601
Modules:All Detects RAM errors. Return the module for repair.
Action:Slice OFFLINE
APP_TIMEOUT
0x8666
Modules:All The field interface unit has not serviced its watchdog within a timeout
(35ms on input modules, 30ms on 8442, 200ms on output modules
except 600ms on 8472).
This has been seen on input modules and indicates that the field
interface unit has stalled or failed to start or failed to warm-start when
requested. All examples were on firmware before build 130.
If the module had recently been started (in the last minute), restart it
and let it try again.
If the module had been running for some time, swap the module to
another and swap back. If it fails again, return for repair.
Action:Slice OFFLINE
IMB_DOUT_RESET
0x8740
Modules:All except 8442
The 8442 reports this fault as
0x0740. The processor has requested a slice reset. This provides a
mechanism to reset the slice without removing / inserting the module.
The slice goes offline but resets itself.
This error is simply a by-product of the reset process; the I/O module
log or processor log may indicate the reason in earlier events.
Action:Slice OFFLINE then it should automatically restart.
IMB_DOUT_DISABLE
0x8741
Modules:All except 8442
The 8442 reports this fault as
0x0741. This provides a means for the processor to disable a slice. Some slice
faults can only be detected by the processor. In this case the
processor must have a mechanism for turning off a faulty slice.
This fault is always a secondary symptom of an earlier fault; the I/O
module log or processor log will indicate the primary fault.
Action:Slice OFFLINE
FIA_CONFIGURE_ERROR
0x8800
Modules:All Appears on startup. Verifies that the field interface adaptor (FIA) has
been configured. Detects serious errors in the field interface comms
link such as a faulty optocoupler or a dead FIA. The slice will not boot.
Re-insert the module; if it fails again, return the module for repair.
