Industrial control configuration technology has become an important component of intelligent manufacturing,and is widely used in the field of industrial control for human-machine interaction interfaces.This paper uses MCGS config-uration software to design and implement a calculator project,and optimizes its appearance in the user window;Using a script program,the calculator's four arithmetic operations,expression display,and reset operations were implemented.The implementation of this project not only solves the computing needs of special control situations such as confidentiality and explosion-proof,but also reduces the waste of resources in user system storage devices.
