“PLC在工厂自动化中具有核心地位的原因在于:PLC的技术具有长期的稳定性.又能适时地推进技术的发展。软硬件均应用方便,即插即用,价格适中,堪称工业控制的适用技术。可以说,当今工业控制所要求的性能,PLC可满足85%～90%。其不足部分也可用其他办法补充。就产品功能而言,PLC在不断提高其技术内涵的前提下,融合了IT技术,包括以太网、因特网、无线网技术和现场总线技术,以及运用软件工程方法提升PLC的编程语言,开发全新的编程系统等。”——PLCopen中国组织主席彭瑜
“PLC in the factory automation has the core status because: PLC’s technology has long-term stability, but also promote the development of technology in a timely manner. Hardware and software are easy to use, plug and play, affordable, called industrial control Can be said that the performance required by today’s industrial control, PLC can meet 85% to 90% of its deficiencies can also be supplemented by other means.In terms of product features, PLC in the continuous improvement of its technical connotation of the premise, Integration of IT technologies, including Ethernet, Internet, wireless networking and fieldbus technologies, as well as software engineering to upgrade PLC programming languages, development of new programming systems, etc. ”- Peng Yu, Chairman of PLCopen China
