00 Null No error
01
to
06 Not used. N/A
07 EECKSMER LLAI EEPROM checksum
during write. Replace the FTA plug-in module or recalibrate.
08 EECNTERR LLAI EEPROM counter error. Replace the FTA plug-in module or recalibrate.
09
to
20 Not used. N/A
21 INPTFAIL Input failure. Replace the IOP or check the FTA wiring.
22 Not used. N/A
23 OUTPUTFL Output failure (AO or DO). Check the output connection at the FTA. If it is
good, try replacing the FTA and/or the
appropriate IOP card.
24
to
25 Not used. N/A
26
DIAGCTFL
1 Input/output loopback failure for
the slot. Replace the IOP when convenient. Use a
Standby Manual device if appropriate.
27
to
28 Not used. Replace the IOP card. If the replacement card
provides the same results, call TAC for
assistance.
29 BADPLUGM Plug-in module failure. Test that the slot is wired correctly. If it is,
replace the FTA plug-in module.
30 Not used. N/A
31 FTAMSMCH FTA mismatched with slot
configuration. Reconfigure or replace the FTA.
32
to
34 Not used. N/A
35 BADADPJP Illegal internal zero
configuration attempted on this
channel. Check for an open thermocouple, fuse, or
replace the IOP.
