mb.setfloat16precision(2) sets how float16 is converted to integer. By default it's 2 decimals (0.01 precision). Change 2 to 0 to convert to integer without any decimals.
Hi! Yes, it works. Not a big problem to convert back to float on master device, but just to clarify. Is it possible to make pure float register (either it can be little or big endian)?

float32 data type is handled as is without any conversion. The script can be modified to convert float16 to float32 instead of int16.
Edit: script has been updated with optional conversion of float16 to float32: https://kb.logicmachine.net/integration/modbus-rtu-tcp-slave/

How do i set up the script to use slave id 1 on the first RS-485 port and slave id 2 on the second RS-485 port on an LM5 Lite?
RE: Universal Modbus TCP/RTU Slave - admin - 12.06.2024
Create two separate scripts, one for each port.

This thread is for modbus slave and you are using master so if you have issues create dedicated topic for your case please.

Check the register description in the device documentation.
