| Abstract: | The basic method of designing a PLC using MCS 51 micro controller is presented in this paper. The PLC has several kinds of input and output channels. Timing function and counting function are supported when hardware circuit is designed. During software development, MCS 51 assemble language is used to emulate PLC instructions. The simulations are correct and efficient. |
