RS485 wiring diagram

The built-in serial port of a computer is usually RS232, which requires a 232-485 converter (active and isolated converters are recommended for industrial environments). After conversion, RS485 is divided into two wires, A and B. A is connected to terminal A on the board and not to terminal B. 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.

If the relay responds, the connection is successful.

Method for changing device address

Introduction to device address

Device offset address refers to offsetting based on the thin code switch address, with the specific relationship being: device address=dip switch address+offset address.
Note: This device does not have a dip switch, so the device address=offset address.

Reading device address

Click on 'Read Address' at the top of the software

Setting and Reading of Offset Address

Click on "Read" or "Set" after the offset address below the software to read or set the offset address of the device.

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.

Introduction to Working Mode Functions

Non lock linkage mode of this machine

The board module itself has optocoupler input and relay output. In this mode, the input optocoupler and relay are directly linked. Namely: the optocoupler input signal takes effect ->the corresponding relay is engaged, the optocoupler input signal is cancelled ->the corresponding relay is disconnected.
In this mode, due to mechanical and program delays, there will be a certain delay from the optocoupler input signal to the relay action, but the maximum delay will not exceed 0.05 seconds.
Due to the fact that all relays are directly linked by optocouplers in this mode, there may be a phenomenon where the serial port cannot operate the relay. This is not an abnormal phenomenon, but rather a situation where the relay is linked by the optocoupler before it is activated after being operated through the serial port.

Local self-locking linkage mode

The module itself is a board module with optocoupler input and relay output. In this mode, every time the optocoupler inputs a signal, the corresponding relay flips once. Namely:
The optocoupler input signal takes effect ->the relay flips (switch from engagement to disconnection, switch from disconnection to engagement);
The optocoupler input signal is cancelled ->the relay does not operate;
This mode also has the delay issue of non lock mode, but the delay time will not exceed 0.05 seconds.
This mode can mainly be used in situations where external signals are triggered to control the start and stop of equipment, such as when an optocoupler is connected to a button and the corresponding relay is connected to an electrical device. Each time the button is pressed, the device will switch between start and stop states.

interlocked mode

The module itself is a board module with optocoupler input and relay output. In this mode, every time the optocoupler inputs a signal, the corresponding relay will engage, and other optocouplers without input signals will disconnect their corresponding relays. Namely:
The optocoupler input signal takes effect ->the corresponding relay is engaged and other relays are disconnected;
The optocoupler input signal is cancelled ->the relay does not operate;
This mode also has the delay issue of non lock mode, but the delay time will not exceed 0.05 seconds.
This mode can mainly be used for external signal triggering to control the start and stop of different devices. For example, if a multi-channel optocoupler is connected to an external button and the corresponding relay is connected to an electrical device, pressing one button will switch the corresponding device to the starting state, and other devices will stop running.

Dual machine non lock linkage mode

This mode requires two devices with the same address and mode to complete. After the two devices are connected through direct 485 or cross 232, the optocoupler status of module 1 will directly control the status of the corresponding relay of module 2, that is:
Module 1's No.1 optocoupler input signal takes effect ->Module 2's No.1 relay is engaged
Module 1's input signal for optocoupler 1 disappears ->Module 2's relay 1 is disconnected
The corresponding delay time of the relay in this mode is longer than the previous modes, but it will not exceed 0.1 seconds (9600 baud rate)
If a 485 bus is used in this mode, multiple devices can be connected in parallel, with each device matching its address, allowing for remote transmission of switch values. For example, if there are multiple low-speed switch signals on site that need to be transmitted to a control room 500 meters away to control alarm lights or electric bells, then only a few modules need to be arranged in the factory and connected to the corresponding modules in the room through two twisted pair shielded wires to complete the task. Similarly, the button signal for operating the computer room can also be directly transmitted to the relay located in the computer room module.

Dual machine self-locking linkage mode

This mode requires two devices with the same address and mode to complete. After the two devices are connected through direct 485 or cross 232, the optocoupler status of module 1 will take effect and flip the corresponding relay status of control module 2, that is:
Module 1's No.1 optocoupler input signal takes effect ->Module 2's No.1 relay flips
The input signal of optocoupler 1 in module 1 disappears ->the relay 1 in module 2 does not operate
The application of this mode is similar to the "dual machine non lock linkage" mode, but it is more suitable for remote control of device start and stop. Simply install a button on the operating end to achieve the action of pressing start and stop once.

Flash on/off function and settings

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: 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;

Flashing and disconnecting settings

Open the "Juying Soaring DAM Series Configuration 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])

Example of Communication Instructions

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".
Modbus protocol Chinese reference: http://www.juyingele.com.cn/software/software/Modbus%20POLL Software and User Tutorial. rar

This product also supports Modbus RTU format.

Modbus Register 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 Modbus device commands 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 holding registers (usually storing device configuration information)

Using a 5-digit code format, the first character determines the register type, and the remaining 4 characters represent the address. Address 1 starts from 0, such as 00001 corresponding to 0000.

② Table of baud rate values correspondence

③ Relay status can be queried through address 30002 or address 00001--00002, but control can only use address 00001--00002.

The data length of 30002 address is 16 bits. It can represent up to 16 relays.

The corresponding results are as follows:

The bit 8 of the data in register 30009 is the same as the data in register 00001.

Similarly, the same goes for optocoupler input. The bit8 and bit9 of register 30003 and registers 10001 and 10002 correspond to the specified hardware.

The register address follows the PLC naming convention, where the real address is obtained by removing the highest bit and then subtracting one.

Instruction generation instructions

Application example and explanation: In addition to the dip switch address, the default broadcast address for this device is 254. When there is only one device on the bus, there is no need to worry about the dip switch address. Simply use the 254 address. When there are multiple devices on the bus, select different addresses through the dip switch and send control instructions based on address differentiation.

Note: The RS232 bus is a 1-on-1 bus, which means there can only be two devices on the bus, such as a computer and a relay board. Only the 485 bus can mount multiple devices.

The instructions can be obtained through the debugging information of the "Juying Soaring DAM Series Configuration 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 0001 corresponding to relay 1.

Common problems and solutions

1. After the relay board is powered, communication cannot be established using the 232 interface and cannot be controlled

Firstly, test whether different baud rates can be controlled. Pay attention to the A+, B-line, and shielded line of the 485 interface. Shielded line is not necessary, but it must be connected in cases of high communication error rate, even if the distance is very close.

2. 485 bus, with more than one device mounted, I sent relay 1 suction and sum at broadcast address 255, but not all modules have relay 1 suction and sum.

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.

3. Siemens PLC and equipment cannot communicate normally

The definition of Siemens 485 bus AB is opposite to that of equipment
