This allows to read register command for the next time
Write multiple registers (function code 16): When writing successfully, the written data will be sent to the
CAN bus.
Send command:
[Device Address] [Command No. 16 (0x10)] [The lower register address is required to be 8 bits high] [Low
8 bits] [The number of data is high 8 bits] [The number of data is lower 8 bits] [The lower data is 8 bits higher ]
[Low 8 bits] [...] [...] [High 8 bits of CRC check] [Low 8 bits of CRC check]
Such as:
Write 5 bytes of data by writing a command: 01 10 00 00 00 05 0A 00 11 00 22 00 33 00 44 00 55 , write
this instruction to the special tool (Modbus CRC 16 calculator), calculate the CRC check value And added to the
instruction: 01 10 00 00 00 05 0A 00 11 00 22 00 33 00 44 00 55 47 84, sent in HEX format, 5 bytes of data will
be written. When written successfully, the data is sent to the CAN bus, ie the CAN bus will send 5 bytes of data:
11, 22, 33, 44, 55. In the CAN message, the frame information and the frame ID are configured by the user in
advance.
Note: The register address of this command is only allowed to be 00 00 and is not allowed to be sent in
format as follows: 01 10 00
