Search on WeChat Jicheng Training The programming language of PLC software has distinct characteristics compared to general computer languages. It is neither a high-level language nor a typical assembly language, and it must meet the requirements of being easy to write and debug. Early PLCs only supported ladder diagram programming and instruction list programming. Currently, … Read more
1. Overview For many years, the Programmable Logic Controller (PLC) has made a leap from wiring logic to storage logic since its inception; its functions have progressed from weak to strong, achieving advancements from logic control to digital control; its application fields have expanded from simple control of individual devices to various tasks such as … Read more
Click “Mechanical Industry Press E-World” to follow quickly A programmable logic control relay is a “programmable”, “general-purpose”, and “intelligent” control relay. Different manufacturers have different product names, such as the electronic control relay “easy” from Germany’s Weidmüller; the intelligent control relay “BoxX” from Turck; the general logic module “LOGO!” from Siemens; Schneider Electric’s “Zelio Logic” … Read more

Focusing on automation training for 14 yearsJicheng Training Network Before understanding how a PLC controls a servo motor, we need to clarify two questions: How does a PLC control a servo motor? And how to design a servo system? We will start from these two questions and detail how PLCs control servos and how they … Read more
From “Old Antique” to Intelligent System: A Record of the Transformation of the S7-400 Rolling Mill Control System in the Metallurgical Industry Do you remember the urgent call I received three years ago? “Engineer Li, the No. 3 rolling mill has stopped again, the old system just can’t hold up anymore!” At that time, I … Read more
Today, fieldbus systems have become an integral part of real-time distributed control, which is an effective way to enhance the safety of control and monitoring production processes. Choosing the right communication technology is crucial in the early stages of project development, as it determines whether control performance can directly reach the field level and the … Read more
PLC is a new generation of general industrial control devices based on microprocessors, integrating computer technology, automatic control technology, and communication technology. It uses user-oriented “natural language” programming for control processes, making it suitable for industrial environments, easy to understand, user-friendly, and highly reliable.PLC is developed based on relay sequential control and is a general … Read more
Anyone engaged in electrical work knows that the automation control provided by PLCs is indispensable for industrial production and technological development. Broadly speaking, a PLC can be understood as a centralized relay extension control cabinet. In practical production applications, PLCs significantly reduce the costs of industrial control and enhance centralized management and automatic control of … Read more
It is well known that industrial production and technological development rely heavily on the automation control provided by PLCs. A PLC can be broadly understood as a centralized relay extension control cabinet. In practical production applications, PLCs significantly reduce the costs of industrial control and enhance centralized management and automatic control of equipment. To master … Read more
