Alarm Frame; Periodic Frame With 1 Hour-History - ADEUNIS WMBUS Pulse Guide Utilisateur

WMBUS Pulse - Guide utilisateur / User guide version V2.2.0

4.2.6 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

4.2.7 Periodic frame with 1 hour-history

This frame (0x48) is sent every hour if the feature is activated in register S321.

Its size is of 31 bytes.
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.
• Bytes 11 to 12 : Delta A0 : index variation of channel A during time interval between 10 to 20 minutes after transmitting the previous frame.
• Bytes 13 to 14 : Delta B0 : index variation of channel B during time interval between 10 to 20 minutes after transmitting the previous frame.
• Bytes 15 to 16 : Delta A1 : index variation of channel A during time interval between 20 to 30 minutes after transmitting the previous frame.
• Bytes 17 to 18 : Delta B1 : index variation of channel B during time interval between 20 to 30 minutes after transmitting the previous frame.
• Bytes 19 to 20 : Delta A2 : index variation of channel A during time interval between 30 to 40 minutes after transmitting the previous frame.
• Bytes 21 to 22 : Delta B2 : index variation of channel B during time interval between 30 to 40 minutes after transmitting the previous frame.
• Bytes 23 to 24 : Delta A3 : index variation of channel A during time interval between 40 to 50 minutes after transmitting the previous frame.
• Bytes 25 to 26 : Delta B3 : index variation of channel B during time interval between 40 to 50 minutes after transmitting the previous frame.
• Bytes 27 to 28 : Delta A4 : index variation of channel A during time interval between 50 to 60 minutes after transmitting the previous frame.
• Bytes 29 to 30 : Delta B4 : index variation of channel B during time interval between 50 to 60 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
• 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
• 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 = 0x0012 so 18 additional pulses
