Chengdu Ebyte Electronic Technology Co.,Ltd.
Address range: 40017(0x0010)～40020(0x0013)
Description: The unit of analog input value is uA
Example: function code 0x03, read AI input.
Assuming AI1 ( current type ) input is 9955uA, the corresponding value should be 0x26E3, AI3 input is 5000uA, the
corresponding value is 0x1388, AI2 and AI4 are 0.

6.1.4 Read analog AO output

Function code: 03, read holding register
Address range: 40033(0x0020)～40036(0x0023)
Description: The unit of analog output value is uA
Example: function code 0x03, read AO output.
Assuming that the output of AO1 ( current type ) is 9955uA, the corresponding value should be 0x26E3, the output of
AI3 is 5000uA, the corresponding value is 0x1388, and the corresponding value of AI2 and AI4 is 0.
