What is the most crucial difference between PLC systems and DCS systems at present? Some people prefer to use PLCs, while experts advocate for DCS. Those with experience, please share your views. Thank you!
What is the most crucial difference between PLC systems and DCS systems at present? DCS originated from instrument control, while PLC originated from electrical control.
As long as the application area differs, PLC systems are primarily used for electrical control, focusing on digital input and output； The DCS system is mainly used in automatic control systems for analog input and output.

I’m learning, I’m learning – what does digital signal mean?
The DCS controls the entire process flow and monitors most of the signals in the plant. Some devices, such as pumps and compressors, have their own controllers, which means that a DCS system is not used. These devices have safety requirements as well as SIL level requirements.
