在可编程逻辑控制器(PLC)和分布式控制系统(DCS)之间如何抉择，要取决于具体的项目和工厂类型。因为应用场合不同，对控制系统的要求也各不相同。
自动化项目要想成功，首先需要自动化工程师、设计工程师一起评估应用需求，然后选择最有效的控制系统平台。这些决定将会对工厂的经营业绩带来长远的影响，在某些情况下，影响可长达25年甚至更多。大多数控制系统的决策，可归结为选择可编程逻辑控制器(PLC)或分布式控制系统(DCS)。有时，某种选择非常适合于一个工厂，而在另外一种情况下，它可能就不适用了。在选择控制系统时考虑的因素越多，就越有助于实现短期和长期目标。
控制系统平台，对自动化系统满足优化生产、维持可用性和获取数据等需求的方式，会有一定的影响。在选择控制系统方面缺乏远见，也可能会影响未来的扩展、流程优化、用户满意度和公司利润
除了一些基本准则之外(比如如何控制过程)，设计团队还必须考虑安装、可扩展性、维护、保养等方面的各种因素。
目前，虽然对小设备来讲，PLC系统可能是最划算的，但DCS系统则提供了更具经济性的可扩展能力，更可能获得较高的初始投资回报。
