3.20世紀80年代初,S5系統(tǒng)進一步升級——U系列PLC,較常用機型:S5-90U、95U、100U、115U、135U、155U
4.1994年4月,S7系列誕生,它具有更際化、更高性能等級、安裝空間更小、更良好的WINDOWS用戶界面等優(yōu)勢,其機型為:S7-200、300、400
5.1996年,在過程控制領(lǐng)域,西門子公司又提出PCS7(過程控制系統(tǒng)7)的概念,將其優(yōu)勢的WINCC(與WINDOWS兼容的操作界面)、PROFIBUS(工業(yè)現(xiàn)場總線)、COROS(監(jiān)控系統(tǒng))、SINEC(西門子工業(yè)網(wǎng)絡(luò))及控調(diào)技術(shù)溶為一體
6.現(xiàn)在,西門子公司又提出TIA(Totally Integrated Automation)概念,即全集成自動化系統(tǒng),將PLC技術(shù)溶于全部自動化領(lǐng)域。
