The technology of PLC has been continuously evolved. It has gradually added more functions such as timing control, analog control, multi-machine communication, etc. from the original function of circuit logic control, and even PCs with integrated industrial computer (using embedded operating system) and PLC architecture. BASE controller, an electronic system that controls machine equipment, manufacturing process flows, and other control modules through digital or analog input/output modules.
The basic requirements for PLC controllers must be flexible and configurable to meet the needs of different plants and applications. But this is not enough. Guo Jiahao said that the new generation of industrial control systems puts more difficult tasks on the PLC, not only hopes to be more efficient, smaller and more flexible, but also built-in protection. To prevent potentially damaging electrostatic discharge (ESD), electromagnetic interference, and radio frequency interference (RFI/EMI), as well as large-value transient pulses that are common in harsh industrial environments.
For decades, Programmable Logic Controllers (PLCs) have been part of factory automation and industrial program control. From simple lighting functions to environmental systems, to chemical processing and other applications, PLC control is inseparable.
