嗟乎！师道之不传也久矣！欲人之无惑也难矣！古之圣人，其出人也远矣，犹且从师而问焉；今之众人，其下圣人也亦远矣，而耻学于师。是故圣益圣，愚益愚。圣人之所以为圣，愚人之所以为愚，其皆出于此乎？爱其子，择师而教之；于其身也，则耻师焉，惑矣。彼童子之师，授之书而习其句读者，非吾所谓传其道解其惑者也。句读之不知，惑之不解，或师焉，或不焉，小学而大遗，吾未见其明也。巫医乐师百工之人，不耻相师。士大夫之族，曰师曰云者，则群聚而笑之。问之，则曰：“彼与彼年相若也，道相似也，位卑则足羞，官盛则近谀。”呜呼！师道之不复，可知矣。巫医乐师百工之人，君子不齿，今其智乃反不能及，其可怪也欤！
圣人无常师。孔子师郯子、苌弘、师襄、老聃。郯子之徒，其贤不及孔子。孔子曰：三人行，则必有我师。是故不必不如师，师不必贤于，闻道有先后，术业有专攻，如是而已。
李氏子蟠，年十七，好古文，六艺经传皆通习之，不拘于时，学于余。余嘉其能行古道，作《师说》以贻之。

从基层的操作人员，到高层的管理人员，过程系统用户都面临持续不断的挑战。传统和专有的 DCS 系统无法适应现代需求的变化，这不但为运营带来风险，并且会增加成本。在系统能力有限的情况下，确保设备持续在线成为一个棘手的难题。如果缺乏关键数据的支撑，推动业务改进就会变成一个既复杂又耗费成本的过程。
PlantPAx 5.0 DCS
罗克韦尔自动化近日在过程解决方案用户组 (PSUG) 活动上宣布计划发布最新版 PlantPAx? 分布式控制系统 (DCS)，以现代化的方法帮助各企业应对工厂生命周期每个阶段的行业挑战。该版本将于 2020 年夏季发布。
利用 PlantPAx 5.0 DCS，不但可以提升工厂所有区域的生产效率，并且可以简化控制系统策略。在这个版本中，罗克韦尔自动化采用了先进的、性能更可靠的过程控制器，可以提高可扩展性和成套设备集成度，同时提供一个简化的低成本架构。嵌入式本机流程对象有助于降低工程成本，并确保项目的一致性。新的网络安全能力和系统认证有助于提升操作的安全性。
罗克韦尔自动化全球过程控制业务总监 Jim Winter 表示：“我们广泛听取了客户意见，包括我们的客户咨询委员会成员的意见，他们指出了促使其生命周期成本上升的关键问题。借助 PlantPAx 5.0，我们在现代 DCS 方法的基础上进一步扩展了功能，并添加创新功能来实现更智能、性能更高、更具成本效益并经得起未来考验的系统。”
