DIAGCTFL

IOM diagnostic circuit failure
272
Check EEPROM.
EEPROM flag error - incomplete EEPROM write resulting in
uncalibrated IOM.
Calibrate the Analog Input or Analog Output IOM (refer to the
"IOM Calibration Procedures" section for the procedure). If the
error persists, replace the IOM.
Input point failed diagnostic.
Check field wiring and the fuses on the IOTA.
Failure in output circuit / field wiring detected by Analog Output
or Digital Output.
Check field wiring and the fuses on the IOTA. If it is good, try
replacing the IOTA and/or the appropriate IOM card.
Stack reaching limit.
IOM firmware stack usage is dangerously close to its limit.
