E.g.:
Register Encoding value Value Result
S301 Decimal 0 Event mode
S320 Hexadecimal 0xD0 Identifier of the probe 1 set to 0xD
S322 Hexadecimal 0x80 Identifier of the probe 2 set to 0x8
S321 Hexadecimal 0x03 For the probe 1:
Detection of high and low thresholds
S323 Hexadecimal 0x02 For the probe 2:
Detection of high thresholds only
S324 Decimal 300 The value of the high threshold of the probe 1 is:
300/10=30°C
S325 Decimal 10 The value of the hysteresis of the high threshold of the probe 1 is:
10/10=1°C
S326 Decimal 50 The value of the low threshold of the probe 1 is: 50/10=5°C
S327 Decimal 5 The value of the hysteresis of the low threshold of the probe 1 is:
5/10=0.5°C
S328 Decimal 400 The value of the high threshold of the probe 2 is: 400/10=40°C
S329 Decimal 20 The value of the hysteresis of the high threshold of the probe 2 is:
20/10=2°C
S330 Decimal -300 The value of the low threshold of the probe 2 is: -300/10=-30°C
S331 Decimal 10 The value of the hysteresis of the low threshold of the probe 2 is:
10/10=1°C
S332 Decimal 12 The acquisition period is 12 minutes
S333 Decimal 6 The number of samples to be measured and stored between two
transmissions is 6
In this example:
• The product compares the measurements every 12 minutes and transmits if necessary
• As the super-sampling factor is 6, there will be a measurement and a storage operation every 12/6=2 minutes
• The value sent will therefore be an average of 6 temperatures collected every 2 minutes
Caution: averaging can reduce the importance of some peaks (maximum values) if the temperature changes quickly.
Take care also over the values of the period and the super-sampling because they have an impact on the consumption of the product. In the
extreme an acquisition period of 1 minute and a super-sampling factor of 10 produces a measurement every 6 seconds.
