What is PLC?
A Programmable Logic Controller (PLC) is an electronic system designed for digital operations in industrial environments. It uses a programmable memory to store instructions for logical operations, sequential control, timing, counting, and arithmetic operations, and controls various types of machinery or production processes through digital or analog input and output. By 2025, the PLC market in China is projected to reach 100 billion RMB. However, China’s market share in PLCs is relatively small. Let’s look at some of the most renowned PLC brands in China. (The ranking is in no particular order and is compiled from online sources for reference purposes only.)

PLC is Packaging Equipments popular Control system
A Programmable Logic Controller (PLC) is widely used in the control of packaging equipment and machinery. PLCs are popular in this field due to their reliability, flexibility, and ease of programming. They are designed to handle the demands of industrial environments and can control a wide variety of machines and processes efficiently.
In packaging operations, PLCs can manage tasks such as filling machine, sealing, labeling machine, and packing. Their programmability allows for quick changes in the production line to accommodate different types of products or packaging requirements. Additionally, PLCs can be integrated with other systems like Human Machine Interfaces (HMIs) and network systems, enhancing automation and monitoring capabilities in packaging facilities.
