PLC plays a huge role in industrial automation control because of its high programming reliability, strong anti-interference ability, flexible combination, simple programming, convenient maintenance and many other advantages. And with the development of computer technology and communication technology, PLC integrates computer technology, automatic control technology and communication technology, and becomes the core equipment to realize the automation of stand-alone machines, workshops, and factories.
A large domestic equipment company's business involves port handling systems, marine engineering equipment systems, coal, iron ore and other mining yard material conveying systems, steel plant material yard conveying systems, thermal power station coal conveying systems, cement plant bulk material conveying systems, etc. , Mainly provides large-scale equipment design, research and development, manufacturing, sales, installation, commissioning, financial leasing and system assembly services in the above-mentioned fields.

And with the development of the market economy, product competition is increasing, and users have higher and higher requirements for the timeliness of after-sales service. How to quickly and effectively solve customer problems has become a difficult problem for customers.
After many communications and visits by Huachen Zhitong technical engineers to understand the needs of customers, they proposed to use HiNet gateway to connect with PLC, combined with PLC cloud remote monitoring system to solve the problem of customer PLC remote programming and debugging. First, according to the working process of the controlled object, use Huachen Zhitong's HDRS (Device Remote Monitoring Internet of Things) cloud platform to create corresponding device accounts. Second, set the parameters of the equipment to be monitored, and then use Huachen Zhitong's hardware HiNet Industrial Intelligence The gateway and the PLC establish a physical connection with the PLC through wired or 3G, wifi and other wireless methods. Finally, remote operations such as real-time monitoring and programming debugging of the controlled object are realized through Hinode windowns Client and PLC programming software. It used to take 2-3 days, but now it only takes a few minutes to complete, and customer satisfaction is greatly improved.
