2.4.1 Periodical transmission with or without historisation

The product enables to measure and send the data from the probe following the diagram bellow.
This periodical transmission can be done with or without historisation of the data.
The product enables to activate or deactivate a probe. The 0x57 frame will be different depending if 1 or 2 probes are activated.
FR
Parameters associated to this mode are:
• Sampling period (register S321), historisation frequency (register S320) and transmission frequency (register S301)
• Activation of the probes (register S324).

Example without historisation:
Register Encoding Value
S321 Decimal 1800
S320 Decimal 1
S301 Decimal 1
S324 Decimal 3
In this example:
• 1 sample (reading) every hour (1800 x 2 seconds = 60 minutes)
• 1 historisation at each sample and the frame is sent immediately (so every
hour)
• The 2 probes are activated so the product will read the temperature on the 2
probes every hour.
Example with historisation:
Register Encoding Value
S321 Decimal 1800
S320 Decimal 1
S301 Decimal 12
S324 Decimal 3
In this example:
• A sample (reading) every hour (1800x2secondes = 60 minutes)
• An historisation done at each sampling (so every hours)
• A transmission is done every 12 historisations (so every 12 hours, so 2 times
a day)
• The 2 probes are activated so the product will read the temperature on the 2
probes every hour.
Result
1 sample every hour
(1800 x 2 seconds = 60 minutes)
1 historisation for each sample
1 transmission for each historisation
The 2 probes are activated
Result
1 sample every hour
(1800 x 2 seconds = 60 minutes)
1 historisation for each sample
1 transmission every 12 historisations
The 2 probes are activated
