欧姆龙的PLC+变频器的组合如果用于泵的顺序控制器，在3个泵组成的系统中控制水压。PLC+变频器的组合对个泵进行连续的闭环控制，另外两个连在平行水管上的泵进行开/关控制。人机界面（MMI）可以进行监控，无线传输可将SMS信号传送至维护。
在美国，市场战略有时甚至比技术本身更让人瞩目，2003年行业内有一个广为流行新词汇：可编程自动化控制器（Programmable Automation Controller，PAC）。
这个崭新的词汇源自于ARC咨询集团市场调查公司的Craig Resnick，他认为，”PLC相当活跃，而且发展良好，具很强的生命力。然而，PLC这个工业的有效工具正在许多方面不断改变，不断增加其魅力。自动化供应商正不断致力于PLC的开发，以迎合市场和特殊用户的需求。功能的增强促使了新系列的系统浮出水面。PAC基于开放的工业标准、具多领域功能、通用的开放平台以及高能。ARC生造了这个词，以帮助用户定义应用需要，帮助制造商在谈到其产品时能更清晰。
是否制造商会将产品名称从PLC改到PAC，还有待观察。但是，GE Fanuc却没有丝毫犹豫，他们立刻接受了PAC的概念，而且在汉诺威展上公开宣布，其新的旗舰控制产品的名称为PACSystems。GE Fanuc使用了这个名称，表达了其产品综合了传统PLC和PC硬件的优点，具有通用的编程环境，Cimplicity Machine Edition软件。有一个单独的软件控制引擎，一个开发工具，多硬件目标编程。硬件不仅包括2个新的PACSystems处理器，还包括GE Fanuc其他的自动化产品，如平板PC、嵌入式PC、MHI和其新的运动控制系统S2K。
“PACSystems代表了控制业的革新，它能使控制集中统一，而非各个完全无关的部件的拼凑，”GE Fanuc自动化（欧洲）的John Pritchard.认为，”一个引擎，加上一个开发工具，用户可以利用强大的工程环境进行多种应用。”
2003年11月Rockwell宣布，其为PAC技术的领导厂商，其产品ControlLogix和CompactLogix PLC事实上就是PAC。
“我们也看到了用户对控制系统数据的无限热情，用户可以收集安全、财务、质保程序等方面的信息，”罗克韦尔自动化Ken Deken认为，”为满足用户的这个要求，用户需要控制器和业务系统之间的直接联系，任何时候都能提供信息。”
随着不断的发展，PAC将采用大量的方法以处理数据，并具有升级，而在多项目控制、集成商务系统分析和生命周期成本管理等方面也能大踏步地前进。
控制系统与计算机控制系统的比较：
能指标计算机控制系统PLC控制系统
可靠商业级工业级
工作方式中断方式，程序等待条件满足扫描方式，条件不满足程序继续执行
编程语言汇编语言、编程语言标准编程语言
工作环境要求较高对环境要求不高，适应工业现场环境要求
