If you open your project in project view, expand the project tree, and then double click on device configuration, now expand your hardware in the middle lower pane until you find the analog input device and channel you have wired the device(s) to. It should show you the addresses you can use to read the values in your PLC programming. Also, if you look to the right of the configuration details in upper middle pane, it shows an overview of assigned I/O memory addresses. Lastly, you must have already downloaded the Hardware configuration matching your needs and hardware setup to the PLC for all this to work the first time.
