I am attempting to use a LabJack UE9 data acquisition device with LinuxCNC using mb2hal. I want to read analog input channels, which the UE9 stores in modbus registers starting at 0 as 32-bit floating point numbers (two 16-bit registers per value).
When mb2hal reads the two registers (function 3), it does not do any conversion. I get exactly the same number in the "float" pin as the "s32" pin. The first register appears to be the high word, and the second register appears to be the low word. I believe I need to concatenate these two 16-bit registers to recover the 32-bit float, and then convert the 32-bit float to a 64-bit float, which is what HAL uses. Are there any components already existing that would help with this, or do I need to write a new component?
