2.1.5.01 Periodic sending with or without backup
The product allows the measurement and periodic transmission of the values of the pressure delta sensor and/or the analog input according to
the following diagram:
Product in standby
Period

sure delta and/or input

ADVICE FROM ADEUNIS : By default the product is set to read the pressure delta every hour (S321 = 1800). For pure periodic transmission, it is
recommended to configure the acquisition period at the desired backup frequency in order to gain considerably in autonomy
Be careful about backup and sending values that will also depend on the network used and its bandwidth.
Note: for a transmission without history, it is sufficient to set register 301 for the pressure delta or register 324 for the analog input 0-10V
(transmission period) to 1 so the product will send a frame to each backup.*
The main parameters associated with this operating mode for the pressure delta are:
• Period of acquisition (S321)
• Backup period (S320)
• Period of transmission(S301)
The main parameters associated with this operating mode for the analog input are:
• Period of acquisition (S323)
• Backup period (S322)
No
• Period of transmission(S324)
The complete list of registers can be found in paragraph 3.4.
Example :
Register Value encod-

In this example:
• The product reads the pressure delta every hours and saves the information.
• No information reading on the analog input.
• The product will perform 5 backups and transmit them 4 times a day.
• The product is in pure periodic emission since the alarms are disabled.
Value Result
1 reading every 3 hours
1800
1800*2sec = 3600 sec = 1h
1 1 backup for each reading
1 sending every 5 backups (5*1h) =
5
every 5 hours
Disabling the periodic mode and alarm
0
for the analog input
0 Delta pressure alarm deactivated
0 Alarm Analog input disabled
0x00 Disabled Channel 1 alarm
0x00 Disabled Channel 2 alarm
