通常，工厂自动化控制系统的核心是控制器（PLC）。它包含在装配线上移动产品的所有逻辑。HMI通常是机器面板或基于PC的工作站，为操作员提供补充或异常数据。然而，越来越需要来自数据分析的操作信息，这推动了对更稳健HMI的需求。在过程自动化中，环境可能是不稳定和危险的，操作员无法看到实际产品，大多数人认为HMI是系统的核心。在这种情况下，HMI是一个中央控制室控制台，它提供了进入过程的完整“窗口”。在PLC环境中，操作员的主要角色是处理异常。状态信息和异常报警有助于让操作员了解过程中发生的情况，在许多情况下，过程可能会“熄灯”。DCS设备需要操作员做出决策并持续与过程交互，以保持过程运行。事实上，利用操作员的流程知识通常对卓越运营和保持流程佳运行至关重要。逻辑执行的速度是一个关键的区别。PLC的设计旨在满足需要10ms或更短扫描速率的高速应用的需求，包括涉及运动控制、高速联锁或电机和驱动器控制的操作。DCS在大多数情况下不必那么快。调节控制回路通常在100至500毫秒范围内扫描。在某些情况下，让控制逻辑更快地执行可能是有害的，可能会导致终控制元件（如阀门）过度磨损，从而导致过早维护和工艺问题。

The extra cost for redundancy, an insurance policy of sorts, may be well worth it in the case of the typical DCS system, but is often not cost-justified for PLC-based systems.Taking the PLC system offline to make configuration and engineering changes may have less impact, since the platform is not running continuously or because the process can be restarted easily. In contrast, configuration changes and tweaks to the DCS system are done on-line, while the process is running virtually non-stop. A blast furnace, for example, is planned to stay on-line continuously for five to seven years.The expectation and desire to be able to create a customized application varies greatly between DCS and PLC users. Because the PLC was originally designed to be a jack of all trades, it’s understood that the development of customized routines and functions is required to meet the unique needs of an application.Pre-engineered solutions, consisting of standards, templates, and extensive libraries, are what DCS application engineers expect out-of-the-box when working with a new system. The highest priority of a DCS is to deliver reliability and availability, which often results in a design which trades unlimited functionality for repeatability and dependability. The significant tradeoff with the DCS is its inability to accept many custom modifications without creating compatibility issues.
