HI,

has somebody used h5.modbus with 16bit floating point values? at the moment i'm not sure if it's working, i only see 32bit floating point.

is 16bit possible?

The read/write multiple holding register functions work with instances of Buffer, so it doesn't matter what is in them. You need to read a Buffer and then read 16-bit float with some stackoverflow magic.
