Type
0x03 (3)
Read Holding Registers
0x04 (4)
Read Input Registers
0x10 (16)
Write Multiple registers
Note:
You can read and write up to 50 registers in a single Modbus request.
Note:
You must respect a timeout of 10s if you send data to SIGFOX and a timeout of 500ms if you modify
all the configuration registers (60007 to 60011). Finally, if you send the 50 data registers in local radio, a time
out of 1.2s must be respected. If you send data to SIGFOX and locally and with the modified configuration
registers, a timeout of 11.7s must be respected.
Note:
If you are sending data in SIGFOX and local radio, the SIGFOX data is sent first and then the local data
is sent.
Note:
During a SIGFOX transmission, the 12 bytes are transmitted.
