With the integration and development of IT and OT technology, the industrial Internet of Things has become the trend of the times, and the related technologies of PLC communication and the Internet of Things will be popular in the future. Common PLC controller communication includes communication between PLC controllers and communication between PLC controllers and other intelligent devices. With the development of industrial control automation, all PLC controller manufacturers attach great importance to the communication function of PLC controllers and have launched their own network systems. The new PLC controller has a communication interface, which is very convenient for communication. Miniaturization and integration will be higher and higher. With the requirements of the market for miniaturization and integration, PLC technology will be more integrated into industrial, automotive, communications and other products. PLC products are characterized by control and data processing. While meeting the functions, the process requirements are also more detailed. With the development of intelligent factories and the Internet of Things, new requirements have been put forward for the technical development of PLC in the fields of joint control of factory equipment, data interaction between PLC and mainframe and other intelligent products, and big data application. This is a new opportunity and a huge challenge. This requires that PLC products have strong environmental adaptability, stability and reliability, can easily access various networks while maintaining a high cost performance ratio, and give full play to the role of PLC products in data acquisition and data interaction.

PLC is a kind of equipment used for automatic control of industrial production. Generally speaking, it can be used directly in industrial environment without any measures. However, despite the above high reliability and strong anti-interference ability, when the production environment is too bad, the electromagnetic interference is particularly strong, or the installation and use is inappropriate, it may lead to program error or operation error, resulting in incorrect input and output, resulting in equipment out of control and misoperation, to ensure the normal operation of PLC. In order to improve the reliability of the PLC control system, on the one hand, the PLC manufacturer is required to improve the anti-interference ability of the equipment; On the other hand, we need to attach great importance to design, installation, use and maintenance. Multi-party cooperation can improve the problem-solving ability and effectively improve the anti-interference performance of the system.
