4.2.3 Network configuration information frame
During the passage into operation mode (from the Park or Command Mode), the following frame (0x20) representing the network configuration
of the product is transmitted:
0 1
Code Status
FR
0x20 Cf Status
0x20 0x42
Description of the frame:
• Byte 2: S200 register, WMBUS channel
• Byte 3: S201 register, frame format
EN
In the example in grey this gives:
• Byte 2=0x18: the WMBUS channel is 24
• Byte 3=0x01: the frame format is B
4.2.4 Keep Alive frame
This frame (0x30) is transmitted only in the event mode at the frequency defined by register 300.

0x30 Cf Status
0x30 0x42
Description of the frame:
• Byte 2: Type of the sensor on channel A. Configured by the user (register 320).
• Bytes 3 to 5: Value measured on channel A.
• If the type of sensor is 0-10V: The value is expressed in µV
• If the type of sensor is 4-20mA: The value is expressed in nA
• Byte 6: Type of the sensor on channel B. Configured by the user (register 322).
• Bytes 7 to 9: Value measured on channel B.
• If the type of sensor is 0-10V: The value is expressed in µV
• If the type of sensor is 4-20mA: The value is expressed in nA
In the example in grey this gives:
• Byte 2=0x02: register 320, channel A configured for a 4-20mA sensor
• Bytes 3 to 5=0x0C3500=800,000 in decimal i.e. A value measured on channel A of: 800,000,x10=8,000,000nA i.e. 8mA
• Byte 6=0x01: register 322, channel B configured for a 0-10V sensor
• Bytes 7 to 9=0x4C4B40=5,000,000 in decimal i.e. a value measured on channel B of: 5,000,000 µV i.e. 5V
