Universal Analog Input Module

Automatic Calibration:

Autocalibration is an automated input path calibration. This insures best

possible accuracy under varying application conditions. Autocalibration

may be turned on or off. When autocalibration is active you may also set

the interval at which the calibration occurs.

.DisableCyclicAutocal 0, 1 BOOL

0: Module auto-calibration is performed on power up, reset, and

reconfiguration as well as according to the .CyclicAutocalPeriod.

1: Module auto-calibration is only performed on module power-up, reset,

and reconfiguration.

Note: Changing the following tags via the set attribute all or module

reconfiguration message will not cause the auto-calibration to be

performed upon acceptance of the configuration.

.Alarm Enable .ProcessAlarmLatch .RateAlarmLatch

.TenOhmOffset .DigitalFilter .RateAlarmLimit

.LowSignal .HighSignal .LowEngineering

.HighEngineering .LAlarmLimit .HighAlarmLimit

.LLAlarmLimit .HHAlarmLimit .AlarmDeadband

.CyclicAutocalPeriod 0-3 INT

Perform module auto-calibration:

0: Only on powerup and reset.

1: Every 1 minute.

2: Every 10 minutes.

3: Every 30 minutes.

Note: Options 1 through 3 are not valid if cyclic autocal is disabled.
