Which is better for the next-generation automated equipment, using a PLC system or a microcontroller?

In the field of industrial automation, an increasing number of next-generation automation equipment utilize controllers to operate machinery. Among the more commonly used systems today are PLCs and microcontrollers. Today, let's explore the PLC and microcontroller systems, as well as their respective advantages in next-generation automation equipment.

Since the 1960s, PLC control systems (Programmable Logic Controllers) have gradually replaced electrical control devices, experiencing rapid development in industrial control. They are specialized digital computing electronic devices designed for industrial production. Since its establishment in 2012, most of Foshan Hanan Electrical and Mechanical Equipment Co., Ltd.'s automation equipment has been operated and controlled using PLC systems. The electrical and programming departments execute logical operations, sequential control, timing, calculations, and arithmetic operations, executing commands that meet customer requirements. These commands control various types of machinery or production processes through digital or analog input/output.

The PLC system is stable and highly reliable. The PLC system is programmed by relevant technical personnel, and the programs within it are specifically designed for a single device's path. To alter the path, a new program must be entered and rewritten. Typically, for the latest generation of automated equipment, the number of input programs can reach 50 or more, making the modification process quite extensive. However, since the programs are fixed and do not change, they offer high stability and are less susceptible to external interference, thus ensuring strong reliability.

Microcontrollers, widely used in the industrial control field, are integrated circuit chips that integrate ultra-large-scale circuit technology onto a single silicon wafer to form a miniature computer system. Next, Foshan Hanan Electrical and Mechanical Equipment Co., Ltd. will explore more applicable fields in microcontrollers and develop automation equipment to a higher level.

The single-chip microcontroller offers flexibility, allowing modifications based on product characteristics. It is compact, highly expandable, and user-friendly, enabling the creation of diverse control systems, data acquisition systems, robots, and other application systems. The microcontroller integrates circuit technology onto a silicon chip to form a computer system, making information modification easy. However, being a computer system controlled by signals, it is susceptible to interference, which can lead to malfunctions in machinery and disrupt the normal operation of automated equipment.
