Transmitting The Keep Alive Frame - ADEUNIS Sigfox DELTA P Guide Utilisateur

Sigfox DELTA P - Guide utilisateur / User guide version V2.0.1
Explanation of thresholds and hysteresis:
High alarm enabling
The parameters associated with this operating mode are:
• The transmission period (equal to zero in this case of use) (S301 or S324)
• The acquisition period (S321 or S323).
• The type of alarm for the pressure delta (S330) or the 0-10 V analog input (S350).
• The high alarm threshold for the pressure delta (S331) or the 0-10 V analog input (S351).
• The high alarm hysteresis for the pressure delta (S332) and the analog input 0-10 V (S352).
• The low alarm threshold for the pressure delta (S333) or the 0-10 V analog input (S353).
• The low alarm hysteresis for the pressure delta (S334) or the 0-10 V analog input (S354).
The complete list of registers can be found in paragraph 3.4.

2.1.6 Transmitting the Keep Alive frame

If the device does not have periodic data configured, and no threshold is exceeded, it may not transmit data for a long time. So, to be sure that
the device is working properly, it transmits a Keep Alive frame (0x30) according to a determined frequency (S300). It is also possible to send this
frame to know instantaneously the delta pressure, the value on the 0-10 V analog input or to know the state of the 2 digital inputs, putting a
magnet during 3 seconds on the "2" of the case or sending a 0x05 downlink frame.
The parameters associated with this operating mode is the setting of the transmission period of the Keep Alive frame (register 300).
