Abstract
Today, programmable logic controllers (PLCs) is the dominant technology deployed in control automation systems in modern factories. The main modeling method of the PLC is based on ladder logic diagrams (LLDs).However, as a system gets more complex, LLD implementations poses a stumbling block in the design of more complex and real-time PLCs.the main objective of this paper is to run a motor in different sequence mode and simultaneously run the light with a predefined delay in industrial control.
