F&F LE-03MQ Modbus energy counter

[Erwin van der Zwart]

While Erwin's code works it easier to use built-in datatype read function:

Code:

-- read 32-bit floating point value from input register nr 123, use word swap
res, err = mb:readinputregistervalue(123, "float32", "w")

Aha, i thought i know most stuff by now but still new items to discover (:

Is this all documented somewhere? 

Thanks admin!

Hi Buuuudzik,

Modbus specification specify daisy chain ( in -> out ) and not a star topology...

The reflections in your star can cause weird behavior..
