You can't, decimal (integer) or HEX (BCD) are the only 2 methods available in the NT21 to display/set numeric data. Floating point data was only introduced in NS series. Use FIX/FIXL or FLT/FLTL instructions in the PLC to convert floating point data to 16/32 bit, and in case you want to convert to BCD afterwards use BIN/BCD instructions.

I see what you mean, but there is no way as far as I know to get direct ASCII data to display on the NT21. There may be other tricks but I would not know. You have to remember NT21 is a pretty old screen.
