2.2.2 Periodical transmission with redundancy
The product enables to add redundancy in the frame sent (cf diagram bellow). Thanks to the redundancy the product will save samples locally in
order to resend them in the next frame.
Parameters associated to this mode:
• Sampling period (register 321), historisation frequency (register 320) and transmission frequency (register 301)
• Activation of the probes (register 324).
• Number of samples to be repeated from a frame to another (register 323).
When redundancy is activated, the frame will contain the number of bytes corresponding to the total number of samples, so S301+S323. At the
start-up of the product, bytes assigned to the redundant samples will be filled with zeros as long as there is no memorized samples.
Example with redundancy:

S321

A sample every hour
(1800 x 2 seconds = 60 minutes)
S320
Decimal
1
1 historisation at each sampling
S301
Decimal

1 transmission every 2 historisations
S324

The 2 probes are activated
S323
Decimal
1
1 sample repeated in each frame
In this example:
• A sample (reading) every hours (1800 x 2 seconds = 60 minutes)
• A historisation at each sampling
• A transmission done every 2 historisations (so every 2 hours)
• 2 probes are activated
• The product will send 2 new samples measured every hour and 1 memorized sample.
