F_Byte_to_Temp : REAL

This function converts a byte raw value into a REAL variable.

Temperature data transmitted with EnOcean® is one byte in size and is sent in a specific format. This data is usually scaled to a specific temperature value.

For example, a value is transmitted from a range of values from 0 to 40°C. The minimum and maximum data value and the raw value are transferred to the function. The output of the function then outputs the temperature as REAL variable.
