 Enter the module address, 0 through 15, in the Value: entry field and click OK.
The ain0_type parameter sets the analog input type for analog input channel 1. There are
four input types available.
 An ain_type of 0 sets the input type to measure 0 to 5V input signals.
 An ain_type of 1 sets the input type to measure 1 to 5V input signals.
 An ain_type of 2 sets the input type to measure 0 to 20mA input signals.
 An ain_type of 3 sets the input type to measure 4 to 20mA input signals.
 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 analog input type for analog input channel 2. See
ain0_type description above.
The ain2_type parameter sets the analog input type for analog input channel 3. See
ain0_type description above.
The ain3_type parameter sets the analog input type for analog input channel 4. See
ain0_type description above.
The ain4_type parameter sets the analog input type for analog input channel 5. See
ain0_type description above.
The ain5_type parameter sets the analog input type for analog input channel 6. See
ain0_type description above.
The ain6_type parameter sets the analog input type for analog input channel 7. See
ain0_type description above.
The ain7_type parameter sets the analog input type for analog input channel 8. See
ain0_type description above.
The ain_filter parameter sets the input filter for all analog inputs. Filtering is used to dampen
process variations or noise. There are four filter selections available.
 An ain_filter value of 0 sets the input filter for 3Hz and the response time to 155ms
at 60Hz and 185ms at 50Hz.
 An ain_filter value of 1 sets the input filter for 6Hz and the response time to 85ms at
60Hz and 85ms at 50Hz.
