The editor will share with you the differences between the upper computer and the lower computer. I hope you will gain something after reading this article. Let's discuss it together.

Differences: 1. The upper computer plays a main control role in the system, mainly as the planning and control of the system, belonging to the decision-making layer, while the lower computer is the specific executive layer, which mainly completes the tasks assigned by the system planning layer. 2. The upper computer refers to the computer in which people can directly issue control commands, while the lower computer is the computer that directly controls the equipment to obtain the status of the equipment.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

What is the upper computer?

The upper computer refers to the computer that can issue the control command directly.

It's usually PC/host computer/master computer/upper computer.

Various signal changes (hydraulic pressure, water level, temperature, etc.) are displayed on the screen.

What is the lower computer?

The lower computer is the computer that directly controls the equipment to obtain the condition of the equipment.

Generally PLC/ single-chip microcomputer single chip microcomputer/slave computer/lower computer and so on.

The difference between the upper computer and the lower computer

Upper computer: the main control in the system, mainly as the planning and control of the system, belongs to the decision-making layer.

Lower computer: the specific execution layer, which mainly completes the tasks assigned by the system planning layer.

The upper computer refers to the computer in which people can directly issue control commands, usually PC, which displays various signal changes (hydraulic pressure, water level, temperature, etc.) on the screen. The command issued by the upper computer is first given to the lower computer, and then the lower computer is interpreted as the corresponding timing signal to directly control the corresponding equipment according to this command.

The lower computer is a computer that directly controls the equipment to obtain the status of the equipment, usually the PLC/ single-chip microcomputer and so on. From time to time, the lower computer reads the equipment status data (usually analog), which is converted into digital signal and fed back to the upper computer.
