Download means that the master sends a command to write a value to the slave object. If
downloaded to a non-existent object, the master will generate an error.

Data Sending data
The order of the four bits in the data is that the high bit is in the back and the low bit is in the front.

example ：
Write 600rpm to the "target speed" of the slave station, the internal unit of 2FF0.09 is rpm, 600 is
decimal, and hexadecimal is 258. Since the length of the object to be written is 4 bits, but the
calculation result is only two Bit, should be filled with 0 in the high order, so the final result = 00 00
