工业界对于分布式控制系统(DCS)与可编程逻辑控制器(PLC)两者孰优孰劣的争论已经持续了至少40年。然而,随着技术的发展,争论并未停止。由于两者功能特性越来越接近,价格差异也在缩小,曾经一度很清晰的选择,现在似乎变得越来越模糊。要想理解这两者之间的争论,就一定要明确这两种平台之间的根本性差异。
要想理解这两者之间的争论,就一定要明确这两种平台之间的根本性差异。例如,DCS体系结构源自一种完整的系统方法,其焦点在于基于网络实现分布式控制,协助作业人员监视并操控工厂中的任何一个区域。通过高性能的确定性网络实现一致、同步并且完整的过程数据正是DCS体系结构的核心。
另一方面,PLC体系结构聚焦于灵活**的本地控制,PLC技术**近的发展为其增加了过程控制能力。当PLC和HMI软件集成在一起时,其**终形态看起来与DCS十分类似,但是这仍旧是一种自建(DIY)的实现方法,意味着工程师必须亲力亲为实现系统的每一个环节。对于控制来说这种方法更加灵活,但是DIY通常意味着在组网和性能上更大的技术风险,其导致的成本增加会在后期慢慢体现。
以前,相对于PLC系统来说,DCS通常更加昂贵,而且与今天面临的状况不同,当年很多工厂对生产速度、产量、废物排放、安全性和遵循法规上的需求并不高。正是因为这样,基于PLC的系统才获得了发展,因为它们能够提供更低的固定资产投资,同时提供的功能也足够用。但是随着时代的变迁,在全球市场范围DCS系统的价格不断降低,制造企业对其需求也随之上升。因此,在投建新自动化项目时,很多控制系统工程师、维护经理和工厂经理开始重新审视DCS和PLC控制系统两者的优劣。
