4 Product Features

4.1 Analog input AI

4.1.1 Analog input AI description

The analog input AI measures the current signal, the acquisition range is 0-20mA or 4-20mA, the accuracy is 3‰,

and the resolution is 12 bits. Adopt single-ended input, sampling frequency 10Hz, input impedance 100Ω.

4.1.2 Analog input AI filter parameters

The filter parameters of the AI channel can be set, the effective value is 1-16, and the default is 6.

Note:

(1) AI channel filter parameter is a filter parameter shared by all AI channels. The larger the filter parameter, the

stronger the anti-interference ability of AI sampling, but at the same time it has time delay.

(2) AI channel filter parameter address is 0x04B0, and the register type is holding register. Function code 0x06,

0x10. When writing AI filter parameters, if the written parameter value is not within the range of 1-16, it will

automatically take the closest value to write. If the write filter parameter is 0, the device will take 1 as the filter parameter,

and Modbus will not return. Wrong instruction

4.1.3 Analog input AI sampling range

Set the sampling range of all AI channels, valid values are 1 and 0 (default 0).

0: Represents 0～20mA

1: Represents 4～20mA

(1) The AI sampling range is shared by all channels. When the AI channel sampling range is configured for

4-20mA sampling, if the current signal is lower than 4mA, the engineering value of the channel is converted to 0. For

signals greater than 20mA, there is no conversion limit, but it cannot exceed 25mA (there is a risk of equipment damage

if it exceeds 25mA).

(2) AI channel sampling range parameter address is 0x04B2, the register type is holding register, function code

0x06, 0x10. When writing the AI channel sampling range parameter, if the value of the parameter written is not within

the range of 0 to 1, it will automatically take the closest value to write. For example, if the write sampling range

parameter is 2, the device will take 1 as the sampling range parameter. And MDOBUS does not return an error command

4.1.4 Analog input AI raw value, engineering value

There are two ways to read the magnitude of the current signal collected by the device:

(1) Read the original value of AI and calculate the input current based on the input impedance.

The address of the AI original value register is 0x0000 ～0x0003, the register type is input register, and the read

Chengdu Ebyte Electronic Technology Co.,Ltd. 【2DI + 2AI + 4DO】MA02-AACX2240 User Manual

function code is 0x04. The value returned by this method is 2 bytes representing a channel, and the range of the value

read is 0～4095. The method of calculating the current is 0～4095 corresponding to 0～25mA.

The register type is discrete input register, and the read function code is 0x04.

  

 󰇛󰇜

(2)Read the AI engineering value and directly convert to get the input current.

The address of AI engineering value register is 0x0064 ～0x0067, the register type is input register, and the read

function code is 0x04. The value returned by this method is 2 bytes representing 1 channel, and the value read is 0 ～

25000.

The method of calculating the current is 0～25000 corresponding to 0～25mA.

  

 󰇛󰇜

4.1.5 Analog input AI calibration

When reading the AI measurement current, when the error is large, it can be calibrated by setting the high point

calibration register and low point calibration register of each channel.

Each channel of AI has an independent high (low) point calibration register. The address of the high point

calibration register is 0x0190～0x0193, and the address of the low point calibration register is 0x0258～0x025C. The

The calibration method can input an accurate current signal for the AI channel and write the value for calibration.

For example, if the AIx channel corresponding to the calibration device has an actual input current of 20mA, then read

the AI original value of the AIx channel and write the original value to the high calibration register of the AI channel.

Generally, the low point calibration can be set to 0 by default.

Note: This function calibration is only used when the error is large. It is not recommended under normal

circumstances.

4.2 Switch input DI

4.2.1 Switch input DI description

Switch input DI to measure level signal or edge pulse signal (rising edge, falling edge). Support dry node collection,

support DI counting function, the maximum count is 65535 (the count is automatically cleared when 65535 is exceeded).

The switch input DI supports three trigger modes of rising edge, falling edge and level (the default rising edge

trigger mode).

The clearing method supports automatic clearing and manual clearing (default automatic clearing).

4.2.2 Switch input DI description

When the switch inputs the DI to collect the signal, it needs to keep multiple sampling periods before confirming.

The filter parameter can be set from 1 to 16 (default 6 sampling periods). The DI filter parameters can be set through the

configuration software

Figure 4-2-1 Setting DI filter parameters

4.3 Switch output DO

4.3.1 Switch output DO description

Switch output DO, with level mode, pulse mode, follow mode (only follow DI). Using C-type relay output

(normally open + normally closed), the single-channel output supports a maximum load (contact capacity) of 30V/10A or

250V/10A.

Each DO output is designed with an output indicator (red LED indication) to indicate whether the output port is on

or off. When the LED indicator is on, it means the relay is closed (normally open on, normally closed off); when the LED

indicator is off, it means the relay is not closed (normally open off, normally closed on).
