Description of the frame:
FR
• Bytes 2 to 4: register 330, low threshold of channel B sensor
• Bytes 5 to 7: register 331, low hysteresis of channel B sensor
In the example in grey this gives:
• Octets 2 à 4=0x2DC6C0=3 000 000 in decimal: register 330, the low threshold value for channel B is: 3 000
000 µV so 3V
• Octets 5 à 7=0x0F4240=1 000 000 in decimal: register 331, the high threshold value for channel B is: : 1
000 000µV so 1V

Description of the frame:
• Byte 2: register 320, number of repetitions
In the example in grey this gives:
• Byte 2=0x02 : the number of repetitions will be 2

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).
• 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
• Bytes 7 to 9: Value measured on channel B.
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
