PLC制造商已经开始关注到基于工业PC控制技术所带来的强大冲击。在应用方面，很难进一步区分PLC控制系统和工业PC控制系统之间的差异，因为这两者均采用了同样类型的微处理器和内存芯片。工业PC的控制系统，除了在灵活性方面相比传统PLC具有截然不同的优势外，还具有能够缩短系统投放到市场的周期，降低系统投资费用，提高从工厂底层到企业办公自动化的数据信息流动效率等优点。可以相信，PLC技术将继续向开放式控制系统方向发展。

　　5总结

　　PLC从工业领域已经扩展到商业、农业、民用、智能建筑等领域。PLC不仅可以用于代替继电器控制的开关量逻辑控制，也可以用于模拟量闭环过程控制、数据处理、通信联网和运动控制等场合。在国民经济的发展过程中起着越来越重要的作用。随着微处理器、网络通信、人机界面技术的迅速发展，工业自动化技术日新月异，未来PLC将朝着集成化、网络化、智能化、开放化、易用性的方向发展。PLC技术虽然面临着来自其他自动化控制系统的挑战，但同时也在吸收它们的优点，互相融合，不断创新，在今后的国民经济各领域将得到更广泛运用。
