由于历史和贸易方面的原因，不同厂家之间的DCS及PLC之间组态数据无法直接兼容，这无疑给产业控制系统的投资带来很多负面的影响。为此，1993年国际电工委员会(IEC)制定了IEC1131 PLC的标准。其中IEC1131-3标准规定有5种形式的编程语言。1998年以后，该标准改为IEC61131。尽管如此，我们看到这也只是解决了一部分PLC组态的兼容性题目，而且PLC组态的兼容性仅停留在界面形态的相似层面上，DCS则根本没有同一标准的组态形式。
      与PLC一样，DCS也需要有相应的组态标准。这种标准将可以极大地保护DCS用户的投资，使得在控制站平台技术版本日新月异以及DCS升级换代过程中，组态资源能够得到充分的利用；不同DCS系统之间也可以有效地共享组态资源；在一体化的DCS系统中，能够采用同一的组态环境，进步DCS的可靠性与可维护性。因此，在信息技术高速发展的，DCS组态的标准化需求是相当重要，也是相当急迫的。

      DCS组态标准的技术困难相对PLC来说要大很多。，人们已经惯了数字与模拟控制信号的混合处理。除了实现跨平台的组态要求外，DCS组态的标准不能像PLC那样使用五种不同风格的语言环境。那么，通过什么技术方法可以促进DCS组态标准的建立呢？我们以为，数据引擎技术是合适的建立DCS组态标准的技术方法。数据引擎技术机理能够在PineCAD图形组态环境与不同DCS控制站计算指令集之间建立一种直接的数据处理的映射关系，这使得无论是 DCS控制站的制造商，还是组态软件的制造商乃至DCS的用户，在推进DCS组态标准化的进程中都不必付出很大的技术投进。
      数据引擎技术除了具备DCS组态标准的技术基础外，还能够消除长期以来DCS控制站与PLC是否存在功能差别的争议，促使PLC真正成为DCS控制站的一种选择。这在DCS技术和贸易两个方面都具有很高的价值。
五、DCS技术方案与工程应用
      数据引擎技术的研究与应用工作在近两年内已经取得很大进展。北京华能新锐控制技术有限公司的研究职员充分利用数据引擎的技术上风，先后研究开发了 PineControl和HNA5000两款DCS系统。其中PineControl在2002年通过了电力公司的技术鉴定。这两种DCS分别以不同的PLC作为控制站，充分体现了数据引擎跨平台运行和构建一体化DCS的能力。在这样的DCS中，所有控制站的内核都是一致的，不因控制对象的不同而有所改变。控制站的部件种类是同类型产品中少的，其硬件的组合非常轻易。这种安装了数据引擎的PLC，其计算、治理与安全实时性能均能够达到目前国际上 DCS产品及技术的水平，而作为PLC平台，该DCS控制站的环境适应能力与可靠性能均过传统的DCS。
      到目前为止，PineControl分布式控制系统已经在四台燃煤发电机组和两套电站辅助系统中运行，HNA5000也将在发电机组中应用。这些DCS应用工程包括350MW进口发电机组的DCS系统改造、新建引进型国产循环硫化床锅炉供热发电机组的DCS项目、大型发电机组锅炉除灰渣控制系统的改造以及发电机组电气控制系统DCS改造等。经过3年多的运行实践，数据引擎技术的设计思想和实现原理均得到了这些发电机组各种运行工况的考验，达到控制品质和安全可靠无故障的良好应用效果，得到DCS用户的高度评价。
      之，数据引擎是DCS的一项新技术，它给DCS未来的技术发展注进了新的活力，促进了DCS体系的标准化，真正实现了DCS控制站的在线组态功能，消除了DCS控制站与PLC的区别
