Development of Decoding Program Module for PLC Output Expansion

PLC출력 확장 디코딩 프로그램 모듈 개발

In this paper, we proposed the program module that expand output points when increased of the output machine for the design of process control system with PLC. In order to incense output points we need the decoding. There is a hardware decoding and a software decoding. In this paper, we proposed the decoding program module which is a software decoding and confirmed feasibility through a simulation.
