PLC(ProgrammableLogicController)自1968年被发明,经过40余年的发展至今,已经是非常成熟的控制器。根据调研机构的估计,过70%的PLC应用是低于128点且单纯是数字I/O,而且工程师只需利用数字I/O和少量的模拟I/O数以及简单的编程技巧就可完成80%的工业应用,所以近年来PLC的趋势是朝向低成本简单的PLC,促进了低成本微型PLC的成长。
    然而,虽然一方面80%的应用需要使用简单的低成本控制器,而另一方面其它的20%应用则出了传统PLC控制系统所能提供的功能。工程师在开发这些20%的应用需要有更高的循环速度,复杂控制运算,更多仿真功能以及能更好地和企业网络集成。此外,工业领域传统的控制类型包括离散控制、过程控制与运动控制,以前往往分别采用独立、的控制器,彼此之间通讯时,需要编制大量的工程化软件,工作量大且复杂。所以这部份的需求使得PLC开始演化成开放式架构,统一的开发软件,覆盖了多种控制类型,完成了控制平台的横向集成,在系统设计、项目实施、运行维护、培训、系统集成、备件等环节上,都大大减少了用户成本。
