Writing a 32bit Float (le) Modbus

General
1

Hi, I want to write one (or more) float (le) registers:

grafik
grafik1034Ă—977 212 KB

for uint32(be) I know how to do (Steve told me):
grafik
first buffer maker with uint32(be) => buffer parser with uint16(be) length: 2 => write FC16

but for float(le) there is no 32/16bit present.

2

Floats in JS are 32bit (AKA 2 words AKA 4 bytes)

3

ok, is there any possibility to recreate 2x 16bit to write registers ?

example from input:
