西門子PLC的MPI通訊詳解隨著科技的進(jìn)步，智能化芯片的發(fā)展逐漸成熟起來設(shè)備的智能化程度也相應(yīng)提高，隨之智能化設(shè)備之間基于開放標(biāo)準(zhǔn)的現(xiàn)場(chǎng)總線技術(shù)構(gòu)成的自動(dòng)化控制系統(tǒng)也逐漸成熟起來。于是西門子PLC除了使用工業(yè)以太網(wǎng)和profibus。

　　設(shè)定時(shí)可根據(jù)負(fù)載轉(zhuǎn)矩特性，選擇相應(yīng)曲線，但也有例外，筆者在調(diào)試一臺(tái)鍋爐引風(fēng)機(jī)的變頻器時(shí)，先將加減速曲線選擇非線性曲線，一起動(dòng)運(yùn)轉(zhuǎn)變頻器就跳閘，調(diào)整改變?cè)S多參數(shù)無效果，后改為S曲線后就正常了。究其原因是起動(dòng)前引風(fēng)機(jī)由于煙道煙氣流動(dòng)而自行轉(zhuǎn)動(dòng)，且反轉(zhuǎn)而成為負(fù)向負(fù)載，這樣選取了S曲線，使剛起動(dòng)時(shí)的頻率上升速度較慢，從而避免了變頻器跳閘的發(fā)生，當(dāng)然這是針對(duì)沒有起動(dòng)直流制動(dòng)功能的變頻器所采用的方法。轉(zhuǎn)矩矢量控制矢量控制是基于理論上認(rèn)為異步電動(dòng)機(jī)與直流電動(dòng)機(jī)具有相同的轉(zhuǎn)矩產(chǎn)生機(jī)理。

　　在我們常用的編程、組態(tài)、通訊還用到了MPI、ASI等技術(shù)。這些技術(shù)協(xié)議實(shí)現(xiàn)西門子PLC主機(jī)與智能從站之間的通訊，甚至兼容符合第三方產(chǎn)品的通訊協(xié)議。西門子通訊大致有MPI網(wǎng)絡(luò)通訊、PROFIBUS網(wǎng)絡(luò)通訊、工業(yè)以太網(wǎng)通訊這三種。
　　西門子PLC的MPI網(wǎng)絡(luò)通訊MPI叫多點(diǎn)接口通信，一般用于小范圍、小點(diǎn)數(shù)現(xiàn)場(chǎng)級(jí)通訊，可實(shí)現(xiàn)西門子PLC的操作面板（TP/OP）和上位機(jī)之間的數(shù)據(jù)交換，例如西門子PLCs7-200/300/400，它的通訊速率19.2Kbit-12Mbit，多可連接32個(gè)接點(diǎn)，通訊距離50m以內(nèi)
