F_Byte_to_Temp : REAL

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

In EnOcean, temperature data are transmitted in a certain format, which is one byte in size. These data are usually scaled to a certain temperature value.

For example, a value is transmitted from a range of values from 0 to 40 °C.

The minimum and maximum data values are now input to the function along with the raw value. The output of the function then outputs the temperature as REAL variable.

VAR_INPUT

byData       : BYTE;
minTemp      : REAL := 0;
maxTemp      : REAL := 40;

byData: Raw data.

minTemp: Minimum temperature.

maxTemp: Maximum temperature.

F_Byte_To_Temp: Temperature value, scaled over minTemp and maxTemp.
