提高PLC应用系统可靠性研究

Research on Enhancing Reliability of the PLC Application System

PLC是以微处理为基础的通用工业控制装置,应用面广,功能强大,使用方便.提高PLC应用系统可靠性对提高劳动生产率、有效利用资源和减少能耗、提高生产安全、改善劳动条件有重要作用.

PLC is an general industry control device taking micro processing as the foundation , （completes logic operation through its memory,sequential control, fixed time, operational orders and so on counting and arithmetic operation, and through digital, simulation - like input and output, controls each kind of type machinery or production process. ） The PLC application surface is broad, the function is formidable, easy to operate. Enhances the PLC application system reliability to enhance the labor productivity, effectively using the resources and the reduced energy consumption, the enhancement production safety, the improvement work condition has the vital role.
