PLC在开放性方面也有了实质性的突破。**多年PLC被攻击的一个重要方面就是它的专有性，现在有了较大的改观。PLC采用了各种工业标准，如IEC 61131，IEEE802.3以太网，TCP/IP，UDP/IP等，各种事实上的工业标准，如Windows NT，OPC等。
PLC在硬件上也有长足进步。微电子技术的进展全都运用到PLC中，元器件的集成度越来越高，促使PLC成本下降和可靠性提高。专为PLC的设计的PLC-on-a-chip芯片业已问世多年。PLC的产品在体系结构和操作系统上都有了质的变化,性能大幅提高。一个机架上可装多个模块。也出现了以Web为基础的PLC系列产品。
PLC、软PLC、IEC 61131在中国的未来
