Reply Frame To A Register Value Request In A Downlink Frame; Data Frame - ADEUNIS Sigfox RC1 ANALOG Guide Utilisateur

sigfox RC1 ANALOG - Guide utilisateur / User guide version V2.0.1
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

Reply frame to a register value request in a downlink frame

Following reception of a downlink frame with the code 0x40, the frame 0x31 is transmitted.
It contains all the values of the registers requested in the downlink frame 0x40.
• Frame (0x40) sent to the product (downlink) :
0 1
Code
0x40 CONF ID1
The CONF IDX (8bits) fields represent the index of the registers to be sent. The corresponding register is 300 +
CONF IDX value.
• Response frame (0x31) from the product:
0 1
Code Cf. Status
VALUE1
0x31 Status
In this example: CONF ID1 is a 2-byte register, CONF ID2 a 1-byte register and CONF ID3 a 2-byte register.
If an error is detected in the request, the returned 0x31 frame will be empty.

Description de la trame :
• 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
