What are the advantages and disadvantages of computer control system composed of single chip microcomputer, industrial computer and PLC?

Advantages: small size, low power consumption, low cost, more common in consumer goods.

Disadvantages: poor anti-interference ability, single processing task and slow operation speed. So it is generally not used in industrial equipment.

Industrial personal computer

Advantages: based on Window or linux operating system, friendly human-computer interaction interface, fast CPU processing speed, rich resources, equipped with different PCI cards, real-time collection of various data information, control of production equipment, strong anti-interference ability and anti-electromagnetic interference.

Disadvantages: high price, big body and high energy consumption.

Programmable Logic Controller (PLC)

Advantages: IO has strong driving ability, easy expansion, graphical development interface, moderate price and strong anti-interference ability, so it is mostly used in industrial equipment.

Disadvantages: the processing task is the same as that of single chip microcomputer.
