Maynuo Electronic M9712 - Coil with the Register Address Allocation

35
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.

Example：
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.
Query: 0x01 0x10 0x0A 0x01 0x00 0x02 0x04 0x40 0x13 0x33 0x33 0xFC 0x23
The Corresponding Logical Response: 0x01 0x10 0x0A 0x01 0x00 0x02 0x13 0xD0
