解决从站设备地址冲突、地址不可修改的协议转换器

​​1、 Hardware device positioning and core value​​

This hardware device is a​​Protocol converter​​. Its core value lies in the fact that it can be flexibly defined into multiple roles through dedicated configuration software to adapt to different application scenarios

• •​​Protocol conversion gateway​​: InModbus RTU, Modbus TCPEven seamless conversion between user private protocols.
• •​​Communication hub (HUB) ​​: expands one master station channel into four independent slave station channels to achieve bus isolation and expansion.
• •​​Intelligent address router​​: solves core pain points such as address conflicts and address immutability of slave station devices.
• •​​Data mapper​​: remaps register addresses to provide a unified and concise data view for upper level master stations. In simple terms, this is a highly flexible hardware platform that defines its functions through software configuration.

​​2. Hardware capability disclosure: looks at the essence through software​

​

​

​

each function of the configuration software corresponds to a core capability of the hardware device.​​

Multi protocol and multi interface support capability​​1. Software interface display​​

• •​​In​​Communication protocol and parameters“Region.) The main station interface of the hardware can be configured as (serial communication) or”Hardware capability demonstration RS485This indicates that the hardware device has at least 以太网.
• •​​One​​Interface​​AndRS485An Ethernet interface​​. It can be used as a serial port device to connect to traditional devices​​The network can also be connected to Ethernet as a network device to meet the physical access requirements of different scenarios.​​Core working mode (selected by software)RS485In software

​​2. Host communication protocol​​Options directly determine the working brain of hardware devices:“Transparent transmission method”Hardware does not parse data and is only used as a simple data channel or switch.

• •​​User Private Agreement​​This is the key to hardware processing of non-standard devices
• •​​. In this mode, the hardware can recognize user-defined protocol structures and pass them through​​: ​​Address code mapping​​Implement channel based routing.“Hardware is transformed into a standard”Protocol converter or manager with advanced capabilities
• •​​Modbus RTU/TCP​​Data processing capability.ModbusCore function one: Address code mapping (resolutionModbusconflict resolution)

​​3. Software functionalityID: In​​

• •​​Station address mapping​​In the tab, users can set up a mapping table to map the data used by the main station“Modbus Logical address”Map to the slave station on a specific physical channel“Actual address”Hardware implementation“When the hardware device receives a message from the main station”.
• •​​Logical address​​When issuing instructions, its internal processor will automatically forward the instructions to based on the mapping table“Channel2”Go up and address the channel​​The actual address is2​​Go up and address the channel“The actual address is01”From the station.​​This means that even the slave stations on the four channelsIDAll of them01In the eyes of the main station, they are also four devices with different addresses.1,2,3,4Hardware solves the problem of address conflicts physically through this approach.​​ Core Function 2: Register Mapping (Simplified Data Access)

​​4. Software functionality​​

• •​​: In​​Register mapping“Modbus In the table, users can define”Master station register address“And with”Slave mapping register“The corresponding relationship.”Hardware implementation
• •​​As shown in the screenshot, when the master station reads a continuous virtual address segment (​​), the hardware will automatically map these requests to discrete actual register addresses (such as0000- 000D, etc.) in the slave station device.0100, 0400For the master station, it is like accessing a large slave station with a continuous data area, greatly simplifying the programming logic of the upper computer and reducing maintenance complexity.​​3、 Typical hardware application scenarios​​

​​Based on the powerful features revealed by the software, this hardware device is suitable for:​​

Equipment reuse and system upgrade

1. 1.​​: Multiple items​​On the bus, using private protocols orRS485The old equipment can easily connect to the new Ethernet based monitoring system.Modbus RTUMulti vendor equipment integrationModbus TCPWhen different brands of devices appear
2. 2.​​When there is an address conflict or different register planning, integration can be achieved without modifying any slave devices through the address and register remapping function of this device.​​Building a highly reliable networkModbusBy connecting devices to different channels, bus isolation is achieved to avoid a single point of failure causing the entire system to crash.
3. 3.​​4、 Summary: A complete solution combining software and hardware​​This four-way protocol converter hardware, together with its feature rich configuration software, constitutes a complete industrial communication solution. Hardware provides stable and reliable multi-channel communication interfaces and a powerful data processing foundation, while software endows hardware with unparalleled flexibility and intelligence.
