Error
Code Failure
Mnemonic
Description Corrective Action
57 F2CAL_FL FTA 2 calibration procedure failed. Recalibrate the FTA.
58
LOSTSYNC Secondary IOP has lost
synchronization. If the primary IOP is in OK, resynch with the
START command. If the primary IOP is in IDLE,
resynch with the IDLE command.
59
WRITENBL AO or DO IOP write enable failure. Replace the IOP at the earliest convenience.
IOP failure can result in indeterminate outputs.
60 MLTINPFL Multiple input failure detected. Replace the IOP.
61 REDNDIAG Redundancy diagnostic failure.
If an AO, replace the FTA’s plug-in module
after forcing IOP A to be the primary.
If an HLAI, replace the IOPs one at a time
following database synchronization.

63 WRONG_H
W Wrong hardware revision for IOP
redundancy Replace the IOP with an IOP that supports
redundancy (proper hardware revision).
64 HWFIFOFL The DISOE Hardware FIFO
diagnostic failed. The PVs of all
points are set to BAD. Replace the IOP.
65
PRVRAMFL The DISOE Private RAM diagnostic
failed. The PVs of all points are set to
BAD. Replace the IOP.
66
SOECLKFL The DISOE clock failed. The PVs of
all points are set to BAD. Replace the IOP.
67 PVVALDFL The PV validation diagnostic failed.
The PVs of all points are set to BAD. Replace the IOP.
68
SOECNTFL The DISOE SOE counter diagnostic
failed. Replace the IOP.
69 DTPATHFL Data path failure. Replace the FTA when convenient.
70 DTPATHTO Data path failure. Replace the FTA when convenient.
71 STAMCHFL The DISOE State Machine diagnostic
failed. The PVs of all points are set to
BAD. Recalibrate the FTA.
