PLC技术展的zui终趋势仍然是人们所争论的焦点之一。大多数人认为，PLC将会继续失去*；更有甚者认为，在工业PC面前，PLC将会一步一步走向死亡；但也有一部分人相信，一些特殊工业应用领域仍将为PLC提供一定的*。

    在工业计算机控制领域，围绕开放与再开放过程控制系统、开放式过程控制软件、开放性数据通信协议，已经发生巨大变革，几乎到处都有PLC，但这种趋势也许不会继续发展下去。随着软PLC(SoftPLC)控制组态软件技术的诞生与进一步完善和发展，安装有SoftPLC组态软件和基于工业PC控制系统的*正在逐步得到增长，这些事实使传统PLC供应商在思想上已经发生了戏剧性的变化，他们必须面对现实，在传统PLC的技术发展与提高方面作出更加开放的高姿态。对于控制软件来讲，这是PLC控制器的核心，PLC供应商正在向工业用户提供开放式的编程组态工具软件，而且对于工业用户表现得非常积极。此外，开放式通信网络技术也得到了突破，其结果是将PLC融入更加开放的工业控制行业。
