From table 4.8.7.1 below, we know that the register address of the present voltage value is 0x0B00,
Query:
0x01 0x03 0x0B 0x00 0x00 0x02 0xC6 0x2F
The Corresponding Logical Response:
0x01 0x03 0x04 0x41 0x20 0x00 0x2A 0x6E 0x1A, within which,
0x41 0x20 0x00 0x2A is the read-back voltage valueand the corresponding floating point value is 10V.

：
The following example sets the load
’
s constant current IFIX as 2.3A at the slave device address of 0x01.
From table 4.8.7.1 below, we know that the IFIX register address is 0x0A01and the floating point takes up
a two-word length.
