Description

Table 62 IOP Box Soft Failure Error Codes

Description
Null Soft failure. No failure
Sample time clock overrun.
IOP task request overflow.
IOP executive resumed a nonwaiting
task.
Diagnostics not run in at least 5
seconds indicates a processing
overload.
Entire diagnostic cycle overran the 2-
minute allocated time in which
diagnostics have to run to
completion.
The FTA is missing.
EEPROM (used to hold calibration
information in Analog Output IOPs)
checksum failure. It usually means an
Analog Output IOP is not calibrated
properly.

Corrective Action
If an IOP card fails and this code is present during restart,
the IOP was disabled, probably by the Watch Dog Timer
time-out circuit, ESD, or RFI. Check the situation.
Replace the IOP if the problem persists.
Applicable to I/O Link Interface only (not presently an IOP
error).
None.
Investigate a possible I/O Link problem. Data
access to the IOP cards may not be operating
properly. Check the High-Performance I/O Link
card, the I/O Link cable, and the IOP cards.
Call TAC for assistance.
Call TAC for assistance.
Investigate control point mix/strategy for an
excessive load. Otherwise, a possible I/O Link
problem exists. Check the High-Performance
I/O Link card, the I/O Link cable, and the IOP
cards.
Same as error code 04.
Install the FTA. If an FTA is present, replace the
FTA or check the FTA cable. (Note: For the
LLMux or RHMUX, this code refers to the
Power Adapter assembly. RTD and TC FTAs
are diagnosed by error codes
50 and 51).
Calibrate the Analog Output IOP card (refer to
the "IOP Calibration Procedures" section for the
procedure). If the error persists, replace the
HLAI, or the AO IOP card, or the FTA.
