Le "4G DTU PLC" réalise le contrôle à distance sans fil de l'automatisation industrielle

In recent years, with the increasing improvement of Internet of Things technology, wireless network communication has gradually broken the limitations of PLC local communication control. Nowadays, PLC remote control has become the basic demand of many customers. So, how to realize the connection between PLC and various configuration software at the lowest cost? Zongheng Intelligent Control 4G DTU helps you solve remote communication problems.

To realize remote connection between PLC and configuration software, the traditional serial communication method requires wiring, which will consume a lot of manpower and material resources; relying on ordinary DTU or other PLC remote control modules requires customized drivers or protocols according to different configuration software secondary development, which virtually increases the cost of the project. Zongheng Intelligent Control 4G DTU perfectly solves problems such as wiring, customized drivers and protocol secondary development.

Implementation principle

1. 4G DTU is connected to various PLCs through serial ports (RS485/RS232).
2. 4G DTU relies on 4G/3G/2G communication network to send data to Zongheng Transmission Cloud.
3. Zongheng Transmission Cloud provides a virtual serial port for connection with configuration software. It distinguishes instrument equipment through card number and DTU serial number, and identifies and distributes it to the corresponding serial port, thereby realizing the connection between PLC and various configuration software.

Simply put, 4G DTU and Zongheng Transmission Cloud are equivalent to an invisible serial port line connecting PLC and configuration software to achieve data interaction.

System advantages

1. Transparent data transmission enables PLC remote control without wiring.
2. 4G DTU is extremely cost-effective, and Zongheng Transmission Cloud is free to use at no charge!
3. It saves the cost of customizing drivers and protocol secondary development.

In addition to connecting downward to PLC and upward to configuration software, Zongheng Intelligent Control 4G DTU can also connect downward to various serial devices. PLCs or instruments from various manufacturers are perfectly compatible, and upward can connect to various third-party software. Customers Self-developed software or mainstream configuration software such as Force Control can be perfectly connected.
