WMBUS ANALOG PWR - Guide utilisateur / User guide version V2.0.0
Details of the fields:
• Frame counter: Frame counter, it increments at each transmission and allows the user to see quickly if a frame has been lost. It counts
from 0 to 7 before looping back.
• HW: This bit is set to 1 when a hardware error has occurred, for example a writing problem in the EEPROM, a reading problem on the
ADC, etc. The product must be returned to the service dept.
E.g.:
A value of the status byte equal to 0xA0 (= 10100000 in binary) gives:
FR
• Bit 7 at 5 = 101 = 0x05 i.e. a frame counter at 5
• Bit 4 at 0 = 00000 in binary i.e. a low battery alarm
4.2.2 Product configuration information frames
During the passage into operation mode (from the Park or Command Mode), the following frames (0x10 to 0x14) representing the application
configuration of the product are transmitted:
EN
0 1
Code Status
0x10 Cf Status
0x10 0xA0
Description of the frame:
• Byte 2: register 300, periodicity of the Keep Alive frame, expressed in tens of minutes
• Byte 3: register 301, periodicity of the transmission, expressed in tens of minutes
• Byte 4: register 320, configuration of the channel A sensor
• Byte 5: register 321, configuration of the events on channel A
• Byte 6: register 322, configuration of the channel B sensor
• Byte 7: register 323, configuration of the events on channel B
• Byte 8: register 306, product mode (Park, Standard (production), Test or REPLI)
In the example in grey this gives:
• Byte 2=0x48: register 300, Keep Alive frame issued every 12 hours
• Byte 3=0x00: register 301, event mode
• Byte 4=0x02: register 320, channel A configured for a 4-20mA sensor
• Byte 5=0x03: register 321:
o Detection of high and low thresholds on channel A
o Detection of event on disabled digital input
o No waiting period
• Byte 6=0x01: register 322, channel B configured for a 0-10V sensor
• Byte 7=0x02: register 323:
o Detection of high and low thresholds only
o Detection of event disabled digital input
o No waiting period
• Byte 8=0x01: register 306, Production mode in progress
WARNING : if none of the channels is configured (value = None in registers 320 and 322), the product will send the configuration frame 0x10
periodically (period defined by register 300)
0 1
Code Status
0x11 Cf Status
0x11 0xA0
Description of the frame:
• Bytes 2 to 4: register 324, high threshold of channel A sensor
• Bytes 5 to 7: register 325, high hysteresis of channel A sensor
