PLC五大主題介紹:
1、外形、體積篇
PLC產(chǎn)品發(fā)展至今從{dy}代的龐然大物,到今天的小型化、易于安裝,它在外形和體積等方面,發(fā)生了巨大變化。無論是從大到小,還是接口、外形的變化,都是為了讓用戶能快速、輕松的安裝、連接和啟動,為此各廠商都在尋求創(chuàng)新,以便讓它更易于操作和擴(kuò)展,進(jìn)而提{gx}率,降低人力和時間成本。
請從外形、尺寸、結(jié)構(gòu)、接線安裝、操作等方面結(jié)合需求描繪PLC的未來。
2、性能、功能篇
如今的PLC,運(yùn)算速度、掃描速度、存儲容量、I/O點(diǎn)數(shù),早已今非昔比。而在多CPU并行、指令的功能與數(shù)量、特殊功能單元、擴(kuò)展能力等方面,也有長足的發(fā)展,如:順序控制、運(yùn)動控制、過程控制等功能的集成,信息安全與設(shè)備診斷的理念等。
無論是小型設(shè)備還是對速度和準(zhǔn)確性要求較高的復(fù)雜設(shè)備,或是特殊需求場合,現(xiàn)在的PLC都可游刃有余的完成工作。
請?jiān)噺腜LC的性能、功能方面,結(jié)合需求說出你對下一代PLC的觀點(diǎn)。
3、通訊性能篇
作為開放趨勢的重要因素之一,PLC的通訊一直為大家所熱烈討論。現(xiàn)場總線的發(fā)展,使得一個個獨(dú)立的PLC系統(tǒng)能夠相互連接,加之工業(yè)以太網(wǎng)與PLC的結(jié)合,PLC系統(tǒng)可方便接入信息化系統(tǒng)之中。為此,各種總線可謂百花齊放:ProfiBus/ProfiNet, CANOpen, DeviceNet,Ethernet/IP, POWERLINK,EtherCAT等。另外,GSM/CDMA/3G等無線網(wǎng)絡(luò)技術(shù),也逐步應(yīng)用。
如何連接外部系統(tǒng)和舊的系統(tǒng)?特殊傳感器如何連接?總線協(xié)議千變?nèi)f化,如何實(shí)現(xiàn)wq兼容?接口是否自診斷?編程接口是否統(tǒng)一?面對眾多來自實(shí)際應(yīng)用的問題,您認(rèn)為,PLC的通訊性能究竟應(yīng)該怎樣發(fā)展?
4、編程軟件篇
從上個世紀(jì)九十年dk始,集成自動化的理念逐漸深入人心。在一個集成自動化體系里,系統(tǒng)中設(shè)備間能夠{zd0}程度上實(shí)現(xiàn)資源利用與共享。然而,集成自動化離不開強(qiáng)大的開發(fā)平臺的支持,開發(fā)工具不僅要支持PLC,還要解決故障診斷、網(wǎng)絡(luò)通信能力以及基本自動化硬件以外的附加高級語言軟件開發(fā)功能。
您對PLC編程軟件有怎樣的應(yīng)用體會或期待,請發(fā)表您的觀點(diǎn)。
5、生命周期篇
傳統(tǒng)的PLC生命周期,包括設(shè)備的選型、采購、設(shè)計(jì)、安裝調(diào)試、維護(hù)維修、服務(wù)等環(huán)節(jié),而模塊化PLC,讓這些環(huán)節(jié)趨向標(biāo)準(zhǔn)和簡化。作為工程師的我們,工作于產(chǎn)品生命周期的各個環(huán)節(jié),或設(shè)計(jì)、或采購、或調(diào)試、或維護(hù),而在這些環(huán)節(jié),您認(rèn)為PLC會有怎樣的變革?
