• Byte 5:
o Bits 0 to 3:
0: deactivated
1: activated
o Bits 4 to 7: The user identifier defined in register 322
• Bytes 6 to 7: Value measured on the probe 2
• Signed value on 16 bits,
• Expressed in tenths of degrees,
• Most Significant Byte first
• The special value 0x8000, equivalent to -3276,8°C is returned in the event of a fault in the sensor.
In the example in grey this gives:
• Byte 2=0xD1:
o Bits 0 to 3 = 0x1: The probe 1 is activated
o Bits 4 to 7 = 0xD: the identifier of the probe 1 defined by the user is equal to 0xD
• Bytes 3 to 4=0x015E: The value measured on the probe 1 is 350/10=35°C
• Byte 5=0x81:
o Bits 0 to 3 = 0x1: The probe 2 is activated
o Bits 4 to 7 = 0x8: the identifier of the probe 1 defined by the user is equal to 0x8
• Bytes 6 to 7=0xFF06: the hexadecimal value 0xFF06 = -250. Hence the value measured on the probe 2 is -250/10=-25°C
