    PLC Concepts This chapter introduces basic and advanced concepts of ladder logic, which is the mostly adopted programming language of PLC. Users familiar with the PLC concepts can move to the next chapter for further programming concepts. However, for users not familiar with the operating principles of PLC, please refer to this chapter to get a full understanding of PLC concepts.
