MCGS industrial control configuration software featuresAs a new type of computer input device, touch screen is the most simple, convenient and natural human-computer interaction method. The touch screen is often used in conjunction with the PLC, which can replace the main electrical appliances such as buttons and switches in the contactor-relay control system, and can also replace the output devices such as indicator lights, meters, and digital displays. Not only can it simplify the wiring, but the reliability of the work is greatly improved. The production of the touch screen screen is achieved by means of the following software.
