 CalibrationDone
 BIT
Set to 1 after calibration cycle completed.
 CalibrationBad
 BIT
Set to 1 if channel calibration coefficients cannot be saved or read properly.
 CalibrationMode
 BIT
Set to 1 when calibration mode is selected.
 GeneralFault
 BIT
 FieldPowerOff
 BIT
Set to 1 when the 24V field power fails. The module status indicator flashes when set.

GainOffsetCalibrate
 BIT
Holds the High or Low Reference settings you selected on the Input Configuration tab from the Module Properties dialog box.
CalibrationClock
 BIT
If selected, calibration mode starts and calibration settings for the selected channels are accepted.
If clear, the accepted current calibration coefficients are stored to selected channels, applied and calibration mode is exited.
QuickCalibration
 BIT
If set to 1, calibration coefficient is stored to all related configurations for selected channels.
