 Enter the module address, 0 through 7, in the Value: entry field and click OK.
The ain0_type parameter sets the measurement type for analog input channel 1. There are
four input types available.
 An ain_type of 0 sets the input point measurement type to degrees Celsius.
 An ain_type of 1 sets the input point measurement type to degrees Fahrenheit.
 An ain_type of 2 sets the input point measurement type to degrees Kelvin.
 An ain_type of 3 sets the input point data measurement as resistance measurement
in ohms.
 To set the ain0_type parameter, click the ain0_type icon and then select the set /
channel parameter command from the Edit menu. The I/O Board parameter dialog is
opened as shown below.
 Enter the analog input type, 0 through 3, in the Value: entry field and click OK.
The ain1_type parameter sets the measurement type for analog input channel 2. See
ain0_type description above.
The ain2_type parameter sets the measurement type for analog input channel 3. See
ain0_type description above.
The ain3_type parameter sets the measurement type for analog input channel 4. See
ain0_type description above.
The ain_filter parameter sets the input filter rate for all RTD inputs. The filter rate is used to
dampen process variations or noise.
 An ain_filter value of 0 sets the input filter rate to 0.5 seconds.
 An ain_filter value of 1 sets the input filter rate to 1 second.
 An ain_filter value of 2 sets the input filter rate to 2 seconds.
 An ain_filter value of 3 sets the input filter rate to 4 seconds.
 To set the ain_filter parameter, click the ain_filter icon and then select the set / channel
parameter command from the Edit menu. The I/O Board parameter dialog is opened as
shown below.
