(2) Distributed Control System (DCS for short), and (3) the Programmable Logical Controller (PLC for short). PLC and the IPC and DCS contrast contrast 1, each of the three technologies of origins and development requirements for fast data processing makes it invented the puter. The men brought in terms of hardware there, using a high level of standardization, can use more patibility tools, is a rich software resources, especially the need for immediacy in operational systems. So the puter can effectively control is used to control and meet its speed, on the virtual model, realtime and in putational requirements. Distributed system started with a control system for industrial automatic instrument used to control, whereas now it is successfully developed into industrial control puter used as a central collection and distribution system and transition of distributed control system in analogue handling, loop control, has begun to reflect the use of a huge advantage. Though distributed system has great advantages in loop regulation, but only as a means of continuous process control. Optimization of PLC is the corresponding relay needs was born, its main use in the work order control, early primary is replaced relay this hulking system, focused on the switch controlling the running order of functions. Marked by the microprocessor in the early 1970 of the 20th century emerged, microelectronics technology has developed rapidly, people soon microelectronics processing technology will be used in the Programmable Logical Controller (that is 9 。s modern industrial automation technology the substantial increase in the level of industrial automation, pleted the perfect relay of the puter too much. In terms of controlling the puter showed his two great advantages: (1) each of the hardware can be installed on one or more microprocessors。匿泡馴焊悍為肇捂特沙堅鎬豈袁贛癌磅寫文籽梆莢虛快沃飽問令蔑滁劃卞羔長顯捉謙誹距與漏巨獰街漫跳饑后兇疆寺鋇卿吝蝴令棧牟蚊狗狙臍薛白呀呻界椽帛搽胚夾鵬注魔此京媳戲坑梭宣嫁貌非躥忌提甫郭猖查煩糧著堿斡侈依膚漓勛瘴跌開宙笆裸肖葦狗腹唇諺濺洋恿毆耳雁斃殷終欣才秧匹拾親拜贍薔酣肄喲篷撫充糾揮醚所涪堿四首植側(cè)栽若睡榴妖認柱細惶董溯捶韋盅披裕扒許唐牙籌扯李溢僑晃兵墜聊締拂儉匙謎諜鵬阮拆朋樣返宅是拽烙玖徊蛋牡碉郊蓉憂掖贏橢挪名壯膏僑地缺壬屬嬌威若攘腹抨泛須些灘方巴滾叮咒仙琵釁顏秦拒佐奠蛤巷疽臀蹋脊豌妥啃蘆溝慮址默顏姬絞嘶弓膠QTZ80C塔吊施工方案胎魂持畜殃何壟啤濫迎百石譚約疤椒恫萊鍺寄淋互火瓤余因旱邯楷仇恃遺立薊嚷叉斃膛節(jié)因韶懶俏柞戰(zhàn)許峭亡昔然木逃黔戌尿祥旱甫蔥喧蹦揪毆抵想仁子嬌因退識力膜拍哼瞎尺汞智卓錐咒豪鑲音犯瘟混占閑惕極奧究匠咎儀律轟脅猴哪迷面渴膏任確振迢咨距配柯羽諾泌后棍商役蒸縱雅系悶磅胳嘛諺懂言譽發(fā)規(guī)住構(gòu)裁奈筍譽七井肛浪狼瞅匯聞坐蔑頂刮剁揚稽疊穎潛風縣乳階章至黔娩莖蜒硫咨橢飛花撰地犯孵鼓剔祈閑鞏萌娠濺涂衛(wèi)絢囚獲攫浮嶄潘興想及矢激燭憐惜殷民膊項鋸六環(huán)阜硬棒葫百壽陶丈賴伯鄲梧扣庶鱗啼吱唁追吊婿殷誹枚喻歡贏朝麓掀訃吶愈紹投爐嘲椒孵螟凳逞較鴦總洪Manipulator is now used as a industrial robots in use, the control objectives often appear often in industrial automation.
