Then, using ladder diagram programming, and maybe few function blocks or add-on instructions, the program can be quickly written, and it will be easy to support for the long term. It is necessary to define the machine's mode control and functions to start, stop, pause or exit a machine cycle. Write it down.
of the heavy machines or to control the voltage and frequency of the power supplies. In this project, study of the PLC has been done in great detail and also several industrial applications have been studied and realized through ladder diagrams. These ladder diagrams are simulated in either PLC trainer or PLC simulator software.

Ladder logic is the main programming method used in PLC. Ladder logic is based on mimic relay logic. The relay logic diagrams are difficult, hence we have selected ladder logic as main programming method. In modern control systems they used relay but these are not used for logic. A relay is a device that controls a switch using magnetic field.
