LoRaWAN 863-870 Pulse - Guide utilisateur / User guide version V2.0.0
4.1.7
Alarm frame
This frame (0x47) is sent if the measured flow of one of the channels exceeds the configured thresh-
old for this channel (registers S326 and S327).

Code
0x47
0x47
Its size is of 6 bytes.
Description of the frame :
•
Bytes 2 to 3: measured flow on channel A when detecting the exceeding of flow, in pulses per
hour.
•
Bytes 4 to 5: measured flow on channel B when detecting the exceeding of flow, in pulses per
hour.
In the example in grey this gives:
•
Bytes 2 to 3: measured flow on channel A when detecting the exceeding of flow, in pulses per hour
= 0x2904 so 10,500 pulses per hour
•
Bytes 4 to 5: measured flow on channel B when detecting the exceeding of flow, in pulses per hour
= 0x206C so 8,300 pulses per hour
4.1.8
Periodic frame with 1 hour-history
This frame (0x48) is sent every hour if the feature is activated in register S321.

Description of the frame :
•
Byte 2: frame index: index of this frame in a multi-message sequence (always null in this configu-
ration).
•
Bytes 3 to 6 : Counter - channel A : counter value of channel A 10 minutes after transmitting the
previous frame.
•
Bytes 7 to 10 : Counter - channel B : counter value of channel B 10 minutes after transmitting the
previous frame.
•
Bytes 11 to 12 : Delta A0 : index variation of channel A during the time interval between 10 to 20
minutes after transmitting the previous frame.
•
Bytes 13 to 14 : Delta B0 : index variation of channel B during the time interval between 10 to 20
minutes after transmitting the previous frame.
•
Bytes 15 to 16 : Delta A1 : index variation of channel A during the time interval between 20 to 30
minutes after transmitting the previous frame.
•
Bytes 17 to 18 : Delta B1 : index variation of channel B during the time interval between 20 to 30
minutes after transmitting the previous frame.
•
Bytes 19 to 20 : Delta A2 : index variation of channel A during the time interval between 30 to 40
