PLC五大主題介紹:


1、外形、體積篇
PLC產品發展至今從{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新，以便讓它更易于操作和擴展，進而提{gx}率，降低人力和時間成本。
請從外形、尺寸、結構、接線安裝、操作等方面結合需求描繪PLC的未來。
2、性能、功能篇
如今的PLC，運算速度、掃描速度、存儲容量、I/O點數，早已今非昔比。而在多CPU并行、指令的功能與數量、特殊功能單元、擴展能力等方面，也有長足的發展，如：順序控制、運動控制、過程控制等功能的集成，信息安全與設備診斷的理念等。
無論是小型設備還是對速度和準確性要求較高的復雜設備，或是特殊需求場合，現在的PLC都可游刃有余的完成工作。
請試從PLC的性能、功能方面，結合需求說出你對下一代PLC的觀點。
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。現場總線的發展，使得一個個獨立的PLC系統能夠相互連接，加之工業以太網與PLC的結合，PLC系統可方便接入信息化系統之中。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等無線網絡技術，也逐步應用。
如何連接外部系統和舊的系統？特殊傳感器如何連接？總線協議千變萬化，如何實現wq兼容？接口是否自診斷？編程接口是否統一？面對眾多來自實際應用的問題，您認為，PLC的通訊性能究竟應該怎樣發展？
4、編程軟件篇
從上個世紀九十年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，系統中設備間能夠{zd0}程度上實現資源利用與共享。然而，集成自動化離不開強大的開發平臺的支持，開發工具不僅要支持PLC，還要解決故障診斷、網絡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功能。
您對PLC編程軟件有怎樣的應用體會或期待，請發表您的觀點。
5、生命周期篇
傳統的PLC生命周期，包括設備的選型、采購、設計、安裝調試、維護維修、服務等環節，而模塊化PLC，讓這些環節趨向標準和簡化。作為工程師的我們，工作于產品生命周期的各個環節，或設計、或采購、或調試、或維護，而在這些環節，您認為PLC會有怎樣的變革？
