I am trying to read an analog input from a digital I/O pin on my 7I76. According to the manual this is possible albeit in 8 bit mode only which is fine for me. I have a spindle drive that provides a 0 5V output for spindle load and I want to read this and show this in my Glade sidepanel.
The manual says: All field input pins are capable of reading the input voltage. These are not highly accurate or high resolution but can be useful for things like potentiometer inputs. Input resolution is 8 bits and input full scale value is 36.3V. Accuracy is +-5%. Software process data modes 1 and 2 allow reading the analog voltage on inputs 0 through 3, in addition to the 32 digital bit inputs. I already used my 0 through 3 so I need to use one of my free inputs left on the 7I76 and 8 bit resolution is fine for this. I looked at PncConf and there is no option to select an analog input for a digital I/O. I run the card in mode 2 combined with a 6I25. How do I go about this and read an analog voltage from a digital I/O pin on my 7I76?
