Seriële servertoepassing

Serial networking server products provide solutions for accessing industrial equipment directly through the network. Traditional serial devices can thus be converted into Ethernet devices that can be monitored and controlled from a LAN or even the Internet. XUNWEI’s serial port server provides different configurations and specifications to meet the needs of special applications, including Modbus protocol conversion, TCP, UDP operating modes, etc. Serial port networking server is the simplest way to remodel existing serial port devices, including PLC, CNC machine tools, instruments, sensors, radio transceivers and other serial port devices. In the field of automation industry, there are thousands of sensors, detectors, PLCs, card readers or other devices connected to each other to form a control network, which serves as a tool for managing data in information systems. The communication interfaces most commonly used to connect these devices are RS232 and RS422/RS485. Network architectures such as bus Ethernet Internet have gradually been widely adopted in the automation industry, replacing traditional serial communication. It is the mainstream of automation system communication. Under this trend, more mature openness represented by TCP/IP and Ethernet. Modern network technology is gradually being applied to various automation systems to connect and control all equipment. . For all equipment manufacturing. For businesses and equipment users, seeking an economical and fast solution that allows existing equipment to be immediately connected to the Internet has become an important issue in grasping competitive business opportunities. It can instantly convert traditional TTL serial ports or RS232/485/422 devices into network devices with network interfaces.

Serial server has a wide range of applications, mainly in access control systems, attendance systems, vending systems, POS systems, building automation systems, self-service banking systems, telecommunications room monitoring, power monitoring, etc.

Most traditional network access control management systems use bus connections. The communication distance of the bus is generally less than 1200m, and there are problems such as wiring in the early stages of access control engineering design. Therefore, TCP/IP access control machines based on the existing Internet have emerged. The communication distance, wiring difficulty, and product technology content for customers are enough to make TCP/IP network access control a new favorite in security projects.

However, due to the high cost of the new TCP/IP network access control machine, and there are problems with compatibility with traditional access control machines after the access control is installed. On the basis of being compatible with traditional access control systems, the serial port server can be upgraded to network TCP/IP access control with only minor changes.

It can quickly transform the traditional access control machine into a network access control machine, and it can be compatible with the original access control machine (that is, there are both traditional access control machines and network access control machines) in the network deployment. serial port server specifically adds transparent transmission parameter settings for security access control product applications, which has greater advantages and flexibility than the serial port servers on the market. After using the serial port server, the traditional access control can be transformed into a TCP/IP network access control.

Here are a few common cases:

1. Unattended weighing:

The company’s serial port server can be used to connect weighing instruments, receipt printers, valves and other supporting equipment to the LAN. Centralized control and data statistics management can be completed using a LAN computer.

2. Remote attendance:

The attendance machine and the company’s serial port server can transmit the attendance data to the server, and it is very convenient to collect attendance statistics from offices across the country.

3. Remote control PLC

The company’s serial port server is added to the PLC, and the programming software is combined with the virtual serial port, thus realizing remote programming of the PLC.
