在同級別小型 PLC 中。因此終確定了用S7-200 SMART PLC + SMART LINE 700 IE觸摸屏替換了歐姆龍PLC+維綸觸摸屏的控制系統(tǒng)的方案。
4產品硬件配置
SIMATIC S7-200 SMART具有集成PROFINET接口,實現(xiàn)低成本與編程設備的通訊、強大的集成工藝功能,有效的解決方案,滿足自動化需求、和靈活的可擴展性、安裝簡單方便、可拆卸的端子、緊湊的結構可大大節(jié)省了控制柜安裝占用空間等特點。因此系統(tǒng)采用了SR40 CPU AC/DC/RLY的PLC作為控制中樞,其電源為AC220V,節(jié)省了電源模塊、數字量輸入為DC24V 24點,可直接與輸入點連接、16點輸出為繼電器輸出,干觸點電壓為5~30VDC或5~250VAC,電磁閥的線圈和接觸器的線圈供電電壓為AC220V,故可直接與PLC輸出電路連接,使系統(tǒng)簡單可靠。
SMART LINE 700 IE觸摸屏準確地提供了人機界面的標準功能,經濟實用,具備高性價比。具有集成PROFINET(以太網)接口,實現(xiàn)低成本與PLC控制設備的通訊,方便,快捷,強大的通訊功能, 256色真彩顯示,800 X 480 dpi寬屏顯示設計和傳統(tǒng)屏幕相比具有更大的可視面積,使單個畫面中可以顯示更多的信息,讓操作員具有更舒適的視覺體驗,高分辨率使畫面更清晰,畫質更細膩。由于使用了SMART LINE 700 觸摸屏,使得設備界面更加美觀,大方,也大大提高了操作的靈活性。下圖為觸摸屏操作界面。見圖5、圖6、圖76應用體會
SIMATIC S7-200 SMART自動控制系統(tǒng)與開關按鈕系統(tǒng)比較,增加了監(jiān)控功能,具有可靠性強、安全性好、準確性高等優(yōu)點,可節(jié)省人員的編制,大大減少因人為的誤操作或開關損壞而造成的故障,從而提高了工作效率,并相對提高了社會經濟效益,是一種有效而實用的自動控制系統(tǒng)。
通過客戶的使用,證明了氣密測漏機控制系統(tǒng)用 PLC 控制的方法是切實可行的。氣密性檢測裝置采用 SIMATIC S7-200 SMART PLC 控制器能大大地提高系統(tǒng)的可靠性和極大地提高了設備自動化程度,并使操作程序更加簡便,客戶較為滿意。the dual PROFIBUS-DP fieldbus network to form the station control level of the system. Water is the basic material condition related to human survival and social development. It is a limited and irreplaceable precious resource and an important guarantee for the sustainable development of economy and society. In recent years, with China's rapid economic growth, the development of urban intensive areas such as the Pearl River Delta has ushered in an unprecedented period of opportunity. However, the progress of industrialization has also led to problems such as water supply shortage and water pollution, and even serious "ecological crisis" events. The state has paid a huge cost of resources and environment. The contradiction between economic development and resources and environment is becoming increasingly acute and needs to be solved urgently.

The State Council issued the outline for the reform of sewage treatment in the Pearl River Delta, and pointed out that the discharge rate of domestic waste should reach
