我們要學(xué)習(xí)的是SIEMENS的PLC,軟件版本是STEP 7 V5.4,控制器與編程軟件之間采用的是MPI通訊方式。
所要熟練掌握的是PLC機(jī)柜內(nèi)的布線方式。能熟練地將變送器的AI信號(hào)和開關(guān)按鈕的DI信號(hào)接入PLC系統(tǒng)中,并能通過(guò)正確地編寫并調(diào)試邏輯,將邏輯輸出的DO正確輸出到相應(yīng)的指示燈或繼電器。
1.一個(gè)機(jī)架上的S7-300PLC模板的安排
在CPU單元右邊可以安裝不超過(guò)八個(gè)模板,模板的配置原則是接口模板(IM.如果有)總是位于3號(hào)槽,個(gè)
信號(hào)模板(SM)的左邊。
2.確定模板的地址:
S7300有兩種編址方法,種是面向槽位編址的地址分配,是300的缺省值的編址方法,,即確定模板起始地址取決于它所在的機(jī)架號(hào)和槽位號(hào),第二種方法是面向用戶的地址分配,即由用戶自由分配。
數(shù)字量模板地址:一個(gè)輸入點(diǎn)或輸出點(diǎn)的地址由字節(jié)部分和位部分組成,,字節(jié)地址取決于其模板的起始地址,位地址是印在其模板上的數(shù)碼號(hào),范圍是0-7,共8位。
模擬量模板的地址:模擬量輸入通道或輸出通道的地址總是一個(gè)字地址,如果塊模擬量模板插在第4號(hào)槽,則它的缺省起始地址為256,隨后的模擬量模板的起始地址每一槽增加16。
