Frames Of Information On The Product Configuration - ADEUNIS WMBUS TEMP Guide D'utilisateur

WMBUS TEMP - Guide utilisateur / User guide version V2.0.0
4.2.1.02 Status Byte
The status byte is broken down in the following way:
Alarm Status Bit 7
No Error
Low bat
HW Error
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.
• Low Bat: bit at 1 if the battery voltage is less than 2.5V, otherwise 0. This information remains permanent.
E.g.:
A value of the status byte equal to 0xA2 (= 10100010 in binary) gives:
• Bit 7 at 5 = 101 = 0x05 i.e. a frame counter at 5
• Bit 4 at 0 = 00010 in binary i.e. a low battery alarm

4.2.2 Frames of information on the product configuration

During the passage into operation mode (from the Park or Command Mode), the following frames (0x10 to 0x12) representing the application
configuration of the product are transmitted:
0 1
Code Status
0x10 Cf Status S300
0x10 0xA2 0x48
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 transmission (periodic mode), expressed in tens of minutes
• Byte 4: register 320, configuration of the internal sensor
• Byte 5: register 321, configuration of the events of the internal sensor
• Byte 6: register 322, configuration of the external sensor
• Byte 7: register 323, configuration of the events of the external sensor
• Byte 8: register 306, product mode (Park, Standard (production), Test or REPLI)
• Byte 9: type of external sensor:
o 0 = disabled
o 1 = unknown
o 2 = FANB57863-400-1
• Byte 10: register 332, periodicity of the acquisition, expressed in minutes
In the example in grey this gives:
• Byte 2=0x48: register 300, Keep Alive frame transmitted every 12 hours
• Byte 3=0x00: register 301, event mode
• Byte 4=0xD0: Registry 320, identifier of the internal sensor given by the user is equal to 0xD
• Byte 5=0x03: Registry 321: detection of high and low thresholds of the internal sensor
• Byte 6=0x80: Registry 322, identifier of the external sensor given by the user is equal to 0x8
• Byte 7=0x02: Registry 323: detection of high and low thresholds of the external sensor
• Byte 8=0x01: register 306, Production mode in progress
• Byte 9=0x02: The type of the external sensor is FANB57863-400-1
• Octet 10=0x0A: register 332, periodicity of acquisition is 10 minutes
