Alarm Frame; Periodic Frame With 1 Hour-History - ADEUNIS LoRaWAN AS-923 Pulse Guide Utilisateur

LoRaWAN AS-923 Pulse - Guide utilisateur / User guide version V1.0.0

4.1.7 Alarm frame

This frame (0x47) is sent if the measured flow of one of the channels exceeds the configured threshold 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 configuration).
• 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.
In the example in grey this gives:
• Byte 2: frame index: index of this frame in a multi-message sequence (always null in this configuration) = 0 (first frame)
• Bytes 3 to 6 : Counter - channel A : counter value of channel A 10 minutes after transmitting the previous frame = 0x00015C4F so
89,167 pulses
• Bytes 7 to 10 : Counter - channel B : counter value of channel B 10 minutes after transmitting the previous frame = 0x0000F74A so
63,306 pulses

Description of the frame:
• Byte 2: frame index: index of this frame in a multi-message sequence
• Bytes 3 to 4 : Delta A0 : index variation of channel A during the time interval between 10 to 20 minutes after transmitting the previous frame.
• Bytes 5 to 6 : Delta B0 : index variation of channel B during the time interval between 10 to 20 minutes after transmitting the previous frame.
• Bytes 7 to 8 : Delta A1 : index variation of channel A during the time interval between 20 to 30 minutes after transmitting the previous frame.
• Bytes 9 to 10 : Delta B1 : index variation of channel B during the time interval between 20 to 30 minutes after transmitting the previous
frame.
