Periodic transmission with redundancy

The product enables to ad redundancy in the frame with historisation (cf scheme here under). Thanks
to redundancy the product will memorize a certain number of data and send them again in the next
frame.
The parameters associated with this mode of operation are:
• Historisation period (register 321) and sending frequency (register 301)
FR
• Enabling and Configuring inputs (register 320)
• Number of data to be repeated (register 340).
Example with redundancy:
Register
EN
S320
S301
S321
S322
S340
In this example:
• 1 historisation of the index each hours (1800x2seconds = 60 minutes)
• 1 sending every 2 savings so every 2 hours
• The 2 channel of the product are activated so the 2 periodic frame are sent (0x5A et 0x5B)
• When it is possible, the product will send for each channel the 2 recent index and the last 4 index
memorized
