8.10.6 Measurement value representation
Temperature measurement
16-bit representation
The measured temperature is multiplied by 10.
Example:
10,1 °C 101 0x0065
12-bit representation
Value representation depends on the measuring unit (°C or °F).
Celsius:
The measured temperature is shifted 4 bit to the left.
Example (°C): 10,1 °C 10 (0x000A <<4) 0x00A0
Fahrenheit:
The measured temperature is divided by 2 shifted 4 bit to the left.
Example (°F): 10,1 °C 5 (0x0005 << 4) 0x0050
Example of a value representation (thermocouple type K)

NOTE
In 12 bit representation, the module‘s diagnostic data are mapped into bit 0 - 3 of the
input data.
