Table 62 IOP Box Soft Failure Error Codes
Error
Code Failure
Mnemonic
Description Corrective Action
23 OUTPUTFL Output point failure. Check which output is failing, then check the
hardware for that output. Replace the hardware
if required.
24 STCKLIM Internal stack usage in the 8051
processor is close to the limit. Call TAC for assistance.
25
Not used. N/A
26 DIAGCTFL Output loopback circuit is bad. Replace the appropriate IOP card.
27 ADPCOMFL I/O Link processor cannot gain
access to the shared RAM. Input
conversion will be prohibited. Replace the IOP card.
28 NOACLINE No external ac line is present in the
LLAI. The 6 Vac is used for power
noise cancellation. Check optical coupler and associated fuse on
the backpanel. Check that the primary (left
side)Power Supply Module in the Power
System is installed and functional.
29 BADPLUGM Bad plug-in module on the FTA. Replace the plug-in module.
30 VTESTFAL Test Volume Reference Failure. PV
is set to NAN by the IOP. Replace the IOP card.
31
FTAMSMCH The FTA type and point configuration
are mismatched. Replace the FTA type or reconfigure.
32 VZERO_FL Zero Reference Volume failure.The
PV is set to NAN by the IOP. Replace the IOP card.
33
BADRJVAL LLAI reference junction value is bad. Check that the reference junction wire or
jumper (P1) is correctly implemented on the
FTA.
34
BADADPJP Probable RAM failure in ADP portion. Replace the LLAI IOP card for the LLAI FTA.
35 ZEROCNFG Bad configuration byte passed to the
ADP. Check the configuration.
36 FTA1FAIL LLMux or RHMUX: FTA 1 has a Soft
failure. LLMux or RHMUX: Check FTA 1.
SI: Correct the error condition at the device
connected to FTA 1.
37 FTA2FAIL LLMux or RHMUX: FTA 2 has a Soft
failure. LLMux or RHMUX: Check FTA 2.
SI: Correct the error condition at the device
connected to FTA 2.
38 CALBABRT Calibration of an IOP card has been
aborted during the procedure. Check the precision voltage/resistance source
for accuracy. Also, make sure that the correct
calibration procedure is being followed
39 BADCALRF Calibration reference input is bad. Replace the HLAI.
