Modbus unsigned int 16

Here are 4 simple functions for bit manipulation:

I tend to use a set of functions that help me avoid typos... //Get bit function getBit(number, bitPosition) { return (number & (1 << bitPosition)) === 0 ? 0 : 1; } //Set Bit function setBit(number, bitPosition) { return number | (1 << bitPosition); } //Clear Bit function clearBit(number, bitPosition) { const mask = ~(1 << bitPosition); return number & mask; } //Update Bit function updateBit(number, bitPosition, bitValue) { const bitValueNormalized = bitValue ? 1 : 0; const clearM…

It is safer to use those.

It would be easier for us, if you would export the whole Flow, so we can check out.
You have only exported 1 record with some values.
