What is the Industrial Role of the Ethernet To Serial Converter?

What is an Ethernet to serial converter?

The Ethernet to serial converter provides the function of converting the serial port to the Internet, can convert the RS232/485/422 serial port into the TCP/IP network interface, and maintain the bidirectional and transparent transmission of the statistical data of the RS232/485/422 serial port and the TCP/IP network interface. The serial port equipment can immediately have the function of a TCP/IP network interface, the network connection is used for developing data communication, and the communication distance of the serial port equipment is greatly expanded.

How to make serial devices in the automation technology industry have the ability to connect to the network and connect to the network immediately? The serial port connects the network server to connect the traditional RS232/422/485 machine equipment to the network immediately. The hardware configuration of the machine equipment, which uses the maintenance of TCP/IP serial port data flow analysis and transmission to operate and manage the method, is a highway bridge dedicated to the design scheme of the serial port to Ethernet interface. Serial devices are connected to the network. The network server is like a microcomputer with a CPU, real-time operating system, and TCP/IP protocol, which facilitates the transmission of data between serial ports and computer devices.

You can use your computer to store, manage methods and equip machines with remote control from anywhere in the world via the Internet. The Ethernet to serial converter provides the function of converting the serial port to the Internet and can convert the RS232/485/422 serial port into a TCP/IP network interface, Maintain two-way transparent transmission of statistical data between RS232/485/422 serial port and TCP/IP network interface. The serial port equipment can immediately have the function of a TCP/IP network interface, the network connection is used for developing data communication, and the communication distance of the serial port equipment is greatly expanded.

The farthest transmission distance of the 485 bus adopted by the serial port equipment is not more than 1200 meters. In order to make the data transmission of this equipment farther, it is necessary to add an Ethernet to serial converter to make the serial port equipment immediately have the function of TCP/IP network interface and communicate data through the Internet. Data from serial devices can be accessed anywhere there is an Internet connection.

In that practical application, the implementation of the Ethernet to serial converter is to map the Ethernet interface of the TCP/IP protocol to a standard serial port under the Windows operate system, and the application program can receive, transmit and control the Ethernet interface just like a common serial port, For example, a general computer has two serial ports COM1 and COM2, the serial port on it can be mapped to COM3, COM4, COM5, etc. Through the Ethernet to serial converter.

The most common communication interfaces used to connect these devices are the RS-232 and RS-422/485 buses. Ethernet/Internet and other network architectures have gradually been widely used in the automation industry, replacing traditional serial communication and becoming the mainstream of automation system communication.

What does the Ethernet to serial converter do

The key function of Ethernet to serial converter is to connect RS485, RS232, and RS422 serial devices to network communication transmission, and to collect and push statistical data. The serial port connection network server selects the British genuine product the import integration IC and inserts the present popular Ethernet connection communication data format, and the adaptation is very omnidirectional. Easily connect machine devices to an Ethernet interface, making it the ideal industrial production communication solution for your data collection, monitoring, and commodity.

The Ethernet to serial converter can select several working methods such as local area network, Internet technology, external network address, cross-gateway IP, etc. It can not only communicate internally but also do real-time monitoring and collection in two different big cities. It is a reliable choice for the application of Ethernet switches in industrial production. When the Ethernet to serial converter is connected, the main parameters of the machine equipment do not need to be changed, because the Ethernet to serial converter has the functions of fully automatic data acquisition and main parameter configuration, For many, this is not only technical to be simple and easy to use. Intelligent practical operation. Perhaps according to different application requirements, the control module can also change the main parameters, network segments, etc. According to the gateway IP that has already been applied, without the customer changing the main parameters of the existing machinery and equipment. Really plug and play.

TCP Server, TCP Client, UDP Server, UDP Client, Socket, and virtual serial port can be selected in the transmission mode. The upper computer and the lower computer can be switched at will in the application. Practically, it has various common fault repair systems such as disconnection inspection, disconnection and reconnection, embedded watchdog, and IP authentication systems for managers.

At the industrial safety level, magnetic couple or optical protection, embedded national standard electrical system, advanced safety protection integrated IC, lightning protection, single pulse, and electromagnetic induction maintenance are selected. Machines and equipment can be used alone or in pairs, and are suitable for point-to-point and point-to-multipoint two-way transparent transmission without changing the original agreement data format.

The working mode of Ethernet to serial converter

The work mode of the Ethernet to serial converter is applicable to the following work mode. The work mode can be converted to the necessary mode by configuring the main parameters of the work through the management method of the Ethernet to serial converter.

1. Network working mode

TCP/IP Server mode

The Ethernet to serial converter records the TCP/IP port number and waits for a connection. The Ethernet to serial converter can be connected to a computer or another embedded computer device.

2. TCP/IP Client mode

The Ethernet to serial converter connects to a specific remote control server TCP/IP port number according to the setting. This server must work in Server mode.

3. UDP broadcast program mode

In this mode, the Ethernet to serial converter will use the UDP broadcast program method to carry out data communication. By default, the statistical data will be sent to the broadcast address 255.255.255.255: 246 using the UDP method. In addition, Ethernet to serial converter slave detailed address: 255.255.255.255: 378

Receiving the data, the customer can also change this main parameter depending on the necessity.

This approach can maintain a plan for a single virtual serial port to communicate with several Ethernet to serial converters. One Ethernet to serial converter can also be maintained push the English one-to-one transparent transmission plan accepted by multiple Ethernet to serial converters.

4. Browse across network segments

Server and Client modes are suitable for cross-network browsing.

TCP/IP Server mode

Set the gateway address of the Ethernet to serial converter as the IP detailed address of the reasonable gateway IP. Set the NAT standard on the gateway IP, map the IP detailed address, and record the port of the Ethernet to serial converter to one TCP/IP port number on the gateway IP, and connect to this port number on the gateway IP.
