Chapter 3 Analog Input Module AS04/08AD-A
3- 19
5. Channel detection
If an input signal exceeds the allowable range of inputs, an error message appears. You can disable this
function so that the module does not produce an alarm or a warning when the input signal exceeds the
input range.
6. Limit detections for channels
This function saves the maximum and minimum values for channels so that you can determine the peak to
peak values.

7. Records for channels (applicable for AS04AD)
Record the input values of the cyclic sampling for each channel. The system saves up to 500 data
points and the recording time is 10 ms.

8. Scale range
You can set the scale range when the format is floating-point. The analog output mode of a channel has
a corresponding digital range. Digital values correspond to analog outputs sent by the module. For
example, if the analog range is -10 V to +10 V, the digital range is -10.0 to +10.0, the HSP scale is 10.0,
and the LSP scale is -10.0. The digital values -10.0 to +10.0 correspond to the analog values -10 V to
+10 V, as the example below shows.
