Data Data from Slave
If there is no error in the data, Bits 4…7 hold the value of the slave
object, with the low order first and the high order last. If there is an error
in the data, the data of these four bits is not equal to the value of the
slave object

Example:
The master sends an "upload" command to the slave:
01 40 F0 2F 09 58 02 00 00 3D(This command is to read the target
speed of the slave 2FF00910)
Slave response:
01 4B F0 2F 09 58 02 00 00 32
Direction: 01 Slave number is 1
4B
Received 2 bits, saved by byte4 and byte5 in the 10 bits of the response
F0 2F
The object index address is 2FF0
09
The object subindex address is 09
58 02 00 00 Data is 00 00 02 58(hex)= 600 rpm
