6、 Communication wiring instructions

1. RS485 cascade connection method

The built-in serial port of a computer is usually RS232, which requires a 232-485 converter (active isolated converters are recommended for industrial environments). After conversion, RS485 is connected to two wires, A and B. A is connected to terminal A on the board, B is connected to terminal B on the board, and the 485 shield can be connected to GND. If there are many devices, it is recommended to use twisted pair shielded wires and adopt a chain network structure.

2. RS232 wiring: The RS232 interface is a DB9 head interface, connected using standard straight through wires.

3. Communication testing

① Select the current serial port number of the device and open the serial port; ② Select the corresponding product model; ③ Change the device address to 254, click "Read Address", and the software will prompt "Read Successful" at the bottom. If the device address read is "0" and the send and command in the lower right corner of the software are correct, it means that the device has successfully communicated with the computer.

4. Analog data explanation

The query rate of DAM debugging software is 3 seconds. After connecting the input signal, the input status and data can be immediately viewed by clicking on the read optocoupler or reading the analog quantity. The relationship between AI data in software and actual input values: actual value=return value * 0.001

9、 Parameter and working mode configuration

1. Equipment address

1.1 Introduction to device address: DAM series devices default to address 0 and use broadcast address 254 for communication. Communication cannot be achieved with 0. Device address=dip switch address+offset address.

1.2. Device Address Reading: After the device communicates normally, write the initial device address to 254, and then click "Read Address" on the top of the software to read the current address of the device.

1.3. Address of dip switch

1. When all five dialing codes are dialed to the "ON" position, it is the address "31"; 2. When all five dialing codes are dialed to the "OFF" position, it is the address "0"; 3. The leftmost 1 is the binary lowest bit. 4. Address Table:

1.4. Setting and Reading of Offset Address: Click on "Read" or "Set" after the offset address in the DAM debugging software to read or set the offset address of the device.

2. Reading and Setting of Baud Rate

Click on "Read" and "Set" in the baud rate settings bar below to read and set the baud rate and address respectively. After the operation, you need to restart the device and modify the computer serial port settings.

3. Working mode

① Normal version: The default input and output of the device are independent of each other and have no relationship.

② Intelligent self-control version: The correspondence between switch input (DI) and analog input (AI) and relay output (DO) requires the use of DLC configuration software for configuration.

4. Flash on/off function and settings

4.1 Introduction to Flashing and Breaking Functions

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

Flashing mode: For each operation of the relay, the relay will close for 1 second (actual time [unit second]=set number * 0.1) and then automatically disconnect;

Flashing mode: For each operation of the relay, the relay will disconnect for 1 second (adjustable time) and then automatically close;

4.2. Flashing and disconnecting settings

Open the "Juying Soaring DAM Debugging Software" and click the dropdown arrow behind the relay mode to select the mode. (The later time can be set by yourself, actual time=fill in the number * 0.1 [unit second]) Note: The flash off mode cannot be written into the device chip. After selecting the flash off mode on the software, all channels are in flash off mode. Single channel control can be achieved by sending a flash off command for a single channel, without affecting the normal control of other channels.

10、 Development documentation description

1. Communication protocol description: This product supports standard Modbus instructions. For detailed instruction generation and parsing methods, please refer to the register table in this article in conjunction with the "MODBUS Protocol Chinese Version". Download link for Modbus protocol manual:Modbus 20POLL Software and User Manual

2. Modbus Register Description

Coil register address table:

remarks:

① Modbus device instructions support the following Modbus addresses: 00001 to 09999 are discrete outputs (coils), 10001 to 19999 are discrete inputs (contacts), 30001 to 39999 are input registers (usually analog inputs), 40001 to 49999 are hold registers (usually storing device configuration information), using a 5-bit code format, with the first character determining the register type and the remaining 4 characters representing the address. Address 1 starts from 0, such as 00001 corresponding to 0000.

② Table of baud rate values correspondence

3. Instruction generation instructions

The instructions can be obtained by checking the debugging information in the "Juying Soar DAM Debugging Software".

Instruction generation instructions: For instructions not listed in the table below, users can generate them themselves according to the Modbus protocol. For reading and writing relay coils, it is actually reading and writing coil registers in the Modbus 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 register operations. For example, reading or writing the status of relay 1 is actually a read/write operation on the coil register 00001 corresponding to relay 1.

11、 Common problems and solutions

1. 232 communication, device control no response, no action: The device communicates with the upper computer using a 232 direct connection. RX to RX, TX to TX, GND to GND

2. Relays can only be turned on and cannot be turned off: check whether 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

3. When multiple devices are hung on the 485 bus, each device's address cannot be the same, and broadcast address 254 cannot be used for communication When there is only one device on the bus, the broadcast address can be used. If there are more than one device, please use a dip switch to distinguish the address for control. Otherwise, the module may not execute instructions correctly due to asynchronous judgment of communication data.
