I'm not familiar with the PV, last time I used one was 16 years ago.
However if you only need to display it some HMI's have a scaling option. so you could scale it like raw = 0-2048 scaled = 0-100.0 It depends on the HMI but by putting a scaling factor in this function can be a simple way.
Some years ago I created a function that scales raw data into anything you want, it takes raw values i.e. 0-32767 and converts it to what ever you need
an example is raw low = 512 raw high = 2048 scaled low = 0 scaled high = 1500. Note this was done for a specific application where internally I needed to convert integer to real to do the calc more accurately, and back to integer (the HMI displayed it as 0-150.0 so even though it was an integer. you could modify it to give out the real value rather than integer.
