I can not figure out how to basically operate a DIO 1 input and use XCTU to export when input changes

I am very new to Xbee and X-CTU coding as i am a student doing this for a first time project. The concept is simple, I have a remote device connected to a coordinator which connects to my PC. I want to use a DIO input so that when any amount of volts is detected i receive the message/frame on my PC. Im using standard XC S2C chips and the modules are connected on the same network as shown on my XCTU screen. If anyone can tell me at least how I can get readings from the end device chip to my PC that would be greatly appreciated.
