3、Communication testing

①Select the current serial port number of the device and open the serial port;

②Select the corresponding product model;

③Change the device address to254Click on "Read Address", and the software will prompt "Read Successful" at the bottom. The device address read is“0”If the sending and command in the lower right corner of the software are correct, it indicates that the device has successfully communicated with the computer.

4Explanation of Analog Data

DAMThe query speed of the debugging software is3sAfter connecting the input signal, you can immediately view the input status and data by clicking on the read optocoupler or read analog quantity.

In softwareAIThe relationship between data and actual input values:

actual value=return value*0.001

9Working mode functions and settings

1、Device Address

1.1、Introduction to device address

DAMThe default address for the series of devices is1Using the broadcast address as254Communicate.

The device address is set through a dip switch.

1.2Address of dip switch

1All five dialing codes have been dialed“ON”When it comes to location, it is the address“32”；

2All five dialing codes have been dialed“OFF”When it comes to location, it is the address“1”；

3far left1It is the lowest binary bit.

4Address Table:

1.3、Reading and Setting of Baud Rate

Click on the baud rate setting bar belowRead "and" Set "can respectively read and set the baud rate and address. After the operation, the device needs to be restarted and the computer serial port settings need to be modified.

2、Flash on/off function and settings

2.1、Introduction to the Flashing and Breaking Function

Manual mode: For each operation of the relay, the relay will flip once (open when closed, close when open);

Flashing mode: The relay closes every time it is operated1Second (actual time in seconds)=Set numbers*0.1）Then disconnect it on its own;

Flashing mode: The relay will disconnect every time it is operated1.Close automatically after seconds (adjustable time);

2.2、Flashing and disconnecting settings

open“Juying SoarsDAMdebuggingsoftware”Click the dropdown arrow after the relay mode to select the mode. (The later time can be set by yourself, the actual time=Fill in numbers*0.1(Unit: seconds)

Note: The flashing and disconnecting mode cannot be written into the device chip. After selecting the flashing and disconnecting mode in the software, all channels are in flashing and disconnecting mode. Single channel control can be achieved by sending a flashing and disconnecting command for a single channel, without affecting the normal control of other channels.

1、communicationProtocol Specification

This product supports standardsmodbusInstructions, for detailed instruction generation and parsing methods, please refer to the register table in this article for reference《MODBUSChinese version of the agreement(Provided in product related downloads)Just enough.

This product supportsmodbus RTUFormat.

2、ModbusRegister Description

This control card is mainly a coil register, which mainly supports the following instruction codes:1、5、15

Coil register address table:

remarks:

①：ModbusThe device instructions support the followingModbusAddress:

00001to09999It is a discrete output(coil)

10001to19999It's a discrete input(contact)

30001to39999It's an input register(Usually an analog input) 40001to49999It's to keep the register(Usually storing device configuration information)

3、Instruction generation instructions

Application example and explanation: In addition to offset address, the local address also has default settings254For the broadcast address. When there is only one device on the bus, there is no need to worry about the dip switch address, and it can be used directly254The address is sufficient. When there are multiple devices on the bus, different addresses can be selected through the dip switch, and control instructions can be sent through address differentiation.

be careful:RS232The bus is1answer1Bus, which means there can only be two devices on the bus, such as a computer and a relay board485Only a bus can mount multiple devices.

Instructions can be obtained throughJu Ying SoarsDAMDebugging software ", to obtain debugging information.

Instruction generation instructions: For instructions not listed in the table below, users can generate them themselves according to the instructions providedmodbusProtocol generation, for the reading and writing of relay coils, is actually aboutmodbusThe reading and writing of the coil register in the register. The address of the relay register has been explained in the previous text, and users only need to generate read and write instructions for the register operation. For example, reading or writing relays1The state is actually related to the relay1Corresponding coil register00001Read and write operations.

11Common problems and solutions

1Relays can only be turned on, not off

Check if the read address is the actual device address, whether there is a return command in the debugging information column, and whether the return command is correct. If the read address fails, there is no return command, or the return command is abnormal, check the communication line and communication converter

2485 busWhen multiple devices are attached, each device address cannot be the same, and broadcast addresses cannot be used254 is used for communication.

The broadcast address can be used when there is only one device on the bus, greater than1Please use dip switches to distinguish addresses when controlling individual devices, otherwise instructions may not be executed correctly due to asynchronous judgment of communication data by the module.
