Please tell the advantages and disadvantages of single chip microcomputer and PLC.

PLC. Advantages: high reliability and stability.

Disadvantages: the architecture of PLC is relatively closed, the hardware systems of PLC manufacturers are incompatible with each other, and the programming languages and instruction systems are also different. When choosing PLC products, users must choose the corresponding control program and learn a specific programming language.

Personal computer Can realize the control function of the original PLC. It has stronger data processing ability, powerful network communication function, the ability to execute more complex control algorithms and almost unlimited storage capacity.

Disadvantages: PC-based automation control also has its shortcomings, and its equipment has poor reliability, real-time performance and stability.
