What is the difference between touch screen program and plc program

Touch screen program is programmed with graphics, PLC program is ladder language.

PLC program is also called programmable controller, is used to control the transmission of electrical equipment, intelligent instruments, which requires engineers to use the programming language to write programs to achieve a variety of control methods.

Touch screen program can be directly connected to the PLC programmable controller to achieve the programmable controller to write programs directly, as well as through the programmable controller programming on the collected variables of the actual monitoring and control.

Expanded Information

PLC programming is an electronic system of digital operations designed for use in industrial environments. It employs programmable memory, which is used to store instructions within it for performing operations such as logic operations, sequence control, timing, counting, and arithmetic operations, and to control various types of machinery or production processes through digital and analog inputs and outputs.

Programmable controllers and their related equipment should be easy to make the industrial control system to form a whole, easy to expand its function of the principle of design.
