Description
Corrective Action
08
EECNTERR
EEPROM counter error. The number
of writes to EEPROM has exceeded
the safe number (10,000). This could
indicate the IOP has not been
calibrated because a virgin EEPROM
will fail this test.
Same as error code 07.
09
EEFLAGER
EEPROM semaphore (incomplete)
error.
Same as error code 07.
09
EEFLAGER
EEPROM semaphore (incomplete)
error.
Same as error code 07.
10
SWTCHERR
No longer used.
No action required.
11
ADRAMCNT
ADP (Analog to Digital Processor –
LLAI only) private RAM contents
failure.
Replace the appropriate IOP card because the
ADP has failed.
12
ADRAMADR
ADP (LLAI only) private RAM
address error.
Replace the IOP card.
13
MBRAMCNT
LLAI shared RAM contents failure.
Replace the IOP card.
14
MBRAMADR
LLAI shared RAM address error.
Replace the IOP card.
15
MBCHKMER
LLAI shared RAM checksum error.
Replace the IOP card.
16
ADROMERR
ADP (LLAI only) ROM checksum
failure.
Replace the IOP card.
17
BADADPER
Application processor (LLAI or STI)
has a communication failure with the
High-Performance I/O Link card.
If the error persists, replace the IOP card.
18
ADSTRTUP
ADP (LLAI only) failed on IOP
startup.
Replace the IOP card.
19
SCANORUN
Input IOP overran its input scan.
Inputs have been lost.
Check for a "chattering" DI point. Another
possible cause would be intermittently bad I/O
link hardware.
20
SCANURUN
DI IOP scan underrun.
No longer used. No action required.
21
INPTFAIL
Input point failure.
Check which input is failing, then check the
hardware for that input. Replace the hardware if
required.
22
BADSECRG
DO IOP card secondary regulator is
not functioning.
Replace the DO IOP card.
