IFC-AI08 is analog input card while CX422 is digital output sensor. IFC-AI08 is not designed for digital type of sensor. You should connect CX422 to IFC-DI08 instead.

to write code , u can refer to IFC-AI08 library reference doc.
there should be function to call to get the value of analog channel that u connect the sensor to.
thanks&regards,

Hi, we do not have library for all the analog sensors, there are thousand of analog :)

Even we shrink the sensor to Sharp Infrared distance sensor, there are at least 5 models that I know of, all these sensors have analog output which provide different information at certain voltage. So writing a universal sample code is not possible.

You will need to ready the datasheet of that particular sensor and under the relationship between voltage and distance, further understand the value of ADC function in IFC-AI08, finally, convert the ADC value to distance.

You can try study theexample code of PR23 R2 where we convert the ADC to distance in cm.
