浩浩乎,平沙无垠,夐不见人。河水萦带,群山纠纷。黯兮惨悴,风悲日曛。蓬断草枯,凛若霜晨。鸟飞不下,兽铤亡群。亭长告余曰:“此古战场也,常覆三军。往往鬼哭,天阴则闻。”伤心哉!秦欤汉欤?将近代欤?
吾闻夫齐魏徭戍,荆韩召募。奔走,连年暴露。沙草晨牧,河冰夜渡。地阔天长,不知归路。寄身锋刃,腷臆谁愬?秦汉而还,多事四夷,中州耗斁,无世无之。古称戎夏,不抗王师。文教失宣,武臣用奇。奇兵有异于仁义,王道迂阔而莫为。呜呼噫嘻!
吾想夫北风振漠,胡兵伺便。主将骄敌,期门受战。野竖旌旗,川回组练。法重心骇,威尊命贱。利镞穿骨,惊沙入面,主客相搏,山川震眩。声析江河,势崩雷电。至若穷阴凝闭,凛冽海隅,积雪没胫,坚冰在须。鸷鸟休巢,征马踟蹰。缯纩无温,堕指裂肤。当此苦寒,天假强胡,凭陵杀气,以相剪屠。径截辎重,横攻士卒。都尉新降,将军复没。尸踣巨港之岸,血满长城之窟。无贵无贱,同为枯骨。可胜言哉!鼓衰兮力竭,矢尽兮弦绝,白刃交兮宝刀折,两军蹙兮生死决。降矣哉,终身夷狄;战矣哉,暴骨沙砾。鸟无声兮山寂寂,夜正长兮风淅淅。魂魄结兮天沉沉,鬼神聚兮云幂幂。日光寒兮草短,月色苦兮霜白。伤心惨目,有如是耶!
吾闻之:牧用赵卒,大破林胡,开地千里,遁逃匈奴。汉倾天下,财殚力痡。任人而已,岂在多乎!周逐猃狁,北至太原。既城朔方,全师而还。饮至策勋,和乐且闲。穆穆棣棣,君臣之间。秦起长城,竟海为关。荼毒生民,朱殷。汉击匈奴,虽得阴山,枕骸徧野,功不补患。
苍苍蒸民,谁无父母?提携捧负,畏其不寿。谁无兄弟?如足如手。谁无夫妇?如宾如友。生也何恩,杀之何咎?其存其没,家莫闻知。人或有言,将信将疑。悁悁心目,寤寐见之。布奠倾觞,哭望天涯。天地为愁,草木凄悲。吊祭不至,精魂无依。必有凶年,人其流离。呜呼噫嘻!时耶命耶?从古如斯!为之奈何?守在四夷。

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。”
