自面世以来，PLC就一直没有停止创新和发展的脚步，它通过利用当前的微处理技术和电子信息技术可以实现扫描。从技术应用趋势来看，电脑软件技术将会在程序化控制器的设计和生产上得到更多的应用，未来必然会出现存储功能强大、运算速度更快、智能化水平更高的PLC产品。一个小型的PLC相当于8-10个继电器，具有十分广泛的应用空间。从产品规模上看，会进一步向超小型及超大型方向发展；从产品的配套性上看，产品的品种丰富、规格，完人机界面、完备的通信设备会更好地适应工业控制的需求。从市场上看，少数几个品牌垄断市场，会出现通用的编程语言。
2、控制系统正在向现场总线方向发展
现场总线是近年来迅速发展起来的一种工业数据总线，它主要解决工业现场的智能化仪器仪表、控制器、执行机构等现场设备间的数字通信以及这些现场控制设备和控制系统之间的信息传递问题。由于现场总线简单、可靠、经济实用等一系列的优点。现场总线是安装在制造或过程区域的现场装置与控制室内的自动控制装置之间的数字式、双向传输、多分支结构的通信网络。现场总线使测控设备具备了数字计算和数字通信能力，提高了信号的测量、传输和控制精度，提高了系统与设备的功能、性能。它不仅是一个基层网络，而且还是一种开放式、新型全分布控制系统。国内现场总线的发展趋势是：①多种现场总线在国内展开激烈竞争，竞争的是应用工程；②自己开发的现场总线产品开始投入市场；③各行业的现场总线应用工程迅速发展。
3、工业自动化控制软件的发展趋势
IDE为每个应用程序组件提供了一种历史记录审核跟踪机制，包括用户标识符、时期与时间戳、以及关于变化的详细的摘要信息。IAS对用户而言可显著降低工程成本，为简化分布式自动化的开发、部署、维护与管理提供了基础。近的工业自动化软件系统正利用的软件技术朝着集成化、网络化、平台化、综合管理等方向发展。
