M .5 Data Type
Modbus communicates using words (the contents of 16bit holding registers).
This means data will be received/send as 16-bit data for each holding register.
Some data types require a higher precision than a whole number (integer), these data types will be multiplied with a factor so the precision is not lost.
When the value for that data type is read it must be divided by the same factor to get the real value.
This also applies to writing the value, then the value must first be multiplied by the factor before writing it to the Holding register.
