3. Product Features
3.1. AI Data Acquisition
3.1.1. AI channels: The device can acquire 0-20mA or 4-20mA current
with a resolution of 12 bits.
Note: There are two ways to read the current value acquired by the device:
· Read AI Engineering quantity registers (holding register): The point value is a floating-point number,
and 4-byte of the returned value represents a channel, and the function code is "03". If the RS485 address of
the device is 1, the hexadecimal instruction to read the data of 2 channels at a time is 01 "03 02 58 00 04 C4
62".
· Read AI Original value registers (holding register): 2-byte of the returned value represents a channel,
and the function code is "03". The method of calculating the current is 0-20mA corresponding to 0-4095. If
the RS485 address of the device is 1, the hexadecimal instruction to read the data of 2 channels at a time is
"01 03 02 BC 00 02 04 57".
3.2. Other Features
3.2.1. AI Filter Parameter
The filter parameter for all AI channels ranges from 1 to 16 (default value is 4).
3.2.2. AI Sampling Range
The valid values are 0 and 1 (default value is 0). 0 means "0-20mA", and 1 means "4-20mA".
3.2.3. AI Original Value High/Low Point Calibration
When there is a large error in reading current value, it can be calibrated through this register. The calibration
method is to give a 0-20mA current signal to the AI channel and write 4095 for calibration.

· AI1 ~ AI2 Engineering quantity: AI Engineering quantity point value on the software divided by 1000 is the
actual current value. For example, the "12021.77" for AI1 Engineering quantity means the measured current is
12.022ma.
· AI1 ~ AI2 Original value: 12bit resolution, 0-20mA corresponds to AI original value 0-4095. For example, the
"2461" for AI1 Original value means the measured current is 12.022mA.
