What is the serial server for? What are the main applications?

Functions and application fields of serial port server;

The serial server provides the function of serial port to network, which can convert RS-232/485/422 serial port into TCP/IP network interface, and realize bidirectional transparent data transmission between RS-232/485/422 serial port and TCP/IP network interface.

The serial device can immediately have the function of TCP/IP network interface and connect to the network for data communication, which greatly expands the communication distance of the serial device.

First, the role of the string server

1. The serial server can immediately connect the traditional RS-232/422/485 devices to the network. The serial device networking server is like a microcomputer with CPU, real-time operating system and TCP/IP protocol, which transmits data between serial ports and network devices. Using serial server, you can access, manage and configure remote devices with your computer anywhere in the world through the network.

Let electrical equipment have serial interfaces, such as RTU, CNC machine tools, testers, etc. , easy to connect with Ethernet, and realize networked management and remote control.

Second, the application field of serial server

Serial server is widely used, which can be used for data acquisition and remote control network engineering transformation.

Give three common examples:

1. Unattended weighing: connect weighing instruments, receipt printers, road gates and other supporting equipment to the local area network by using a serial server, and complete centralized control and data statistics management by using a local area network computer.

2. Remote attendance: Attendance machine and serial server can transmit attendance data to the server, which is very convenient for attendance statistics of offices all over the country.

3.PLC remote control: PLC adds a serial port server, and programming software combines with a virtual serial port to realize PLC remote programming.

The serial server can also be used in new energy, electric power, intelligent transportation, intelligent manufacturing, environmental monitoring and petrochemical industries.

And other industries.

In a word, the serial server is an essential network device to realize Internet of Things communication, remote control and data acquisition. An excellent serial server should have industrial-grade high performance and rich expansion functions.
