检查DCS迁移

这个问题的封面故事ApplicationAutomation.谈谈实施分布式控制系统（DCS），该出版物经常涵盖的主题，并将继续覆盖。作者提供有关如何管理切换过程的建议。他们解释说：“切换是指定用于保持到位的较大自动化系统的部分的点被移至新平台。”此外，他们指出了在DCS交付前的步骤以及最终实现切换过程。在DCS到达后，他们通过步骤向用户引导用户应在实际切换前进行。它们描述了三种类型的切换：冷，热，混合，以及它们的优缺点。

尽管传统控制系统仍然可能在30年后工作仍然很好，但并不意味着它是有效，可靠，安全地或成本有效的。来自2017年5月的问题控制工程: "In its 2015 report, ‘Distributed Control Systems Worldwide Outlook,’ the ARC Advisory Group estimated that $65 billion worth of installed process automation systems in the world today are nearing the end of their useful lifecycles, which, in many cases, can exceed 25 years. Many of these systems-as much as $12 billion worth-are some of the original distributed control systems (DCSs) installed in the late 1970s. Ironically, many manufacturers treat their business systems and email servers very differently than their process control systems. Companies make a concerted effort to keep IT infrastructure current. The same level of emphasis is not yet common practice for plant automation."
