2.現(xiàn)場(chǎng)總線的選擇
2.1現(xiàn)場(chǎng)總線技術(shù)的選擇
現(xiàn)場(chǎng)總線集控制技術(shù)、計(jì)算機(jī)技術(shù)、通信技術(shù)于一體,是當(dāng)今自動(dòng)化領(lǐng)域技術(shù)發(fā)展的熱點(diǎn)之一。這項(xiàng)技術(shù)可將多個(gè)智能控制儀表連接成網(wǎng)絡(luò)系統(tǒng),實(shí)現(xiàn)分布式計(jì)算機(jī)控制,提高檢測(cè)和控制精度,改善系統(tǒng)的動(dòng)態(tài)響應(yīng)速度,提高系統(tǒng)安全性,從而得到了廣泛的應(yīng)用。
近年來,幾種有影響的現(xiàn)場(chǎng)總線技術(shù)已在一些特定的應(yīng)用領(lǐng)域里顯示出各自的優(yōu)勢(shì)。在此,我們選定了現(xiàn)為德國(guó)和歐洲標(biāo)準(zhǔn)的PROFIBUS(Process Fieldbus)現(xiàn)場(chǎng)總線。一方面由于它是目前數(shù)據(jù)傳輸率快的一種現(xiàn)場(chǎng)總線,傳輸率高可達(dá)12Mbps,另一方面它能夠很好的與西門子的傳動(dòng)設(shè)備相配合,并與西門子PLC(Programmable Logic Controller)結(jié)合緊密且組態(tài)簡(jiǎn)便。
2.2 PROFIBUS現(xiàn)場(chǎng)總線簡(jiǎn)介
參照ISO/OSI參考模型,PROFIBUS現(xiàn)場(chǎng)總線只包含物理層、數(shù)據(jù)鏈路層和應(yīng)用層。由PROFIBUS-DP,PROFIBUS-FMS, PROFIBUS-PA組成PROFIBUS系列。
PROFIBUS-DP:經(jīng)過優(yōu)化的高速、廉價(jià)的通信連接,專為自動(dòng)控制系統(tǒng)和設(shè)備級(jí)分散I/O之間通信設(shè)計(jì),使用PROFIBUS-DP模塊可取代價(jià)格昂貴的24V或0~20mA并行信號(hào)線。用于分布式控制系統(tǒng)的高速數(shù)據(jù)傳輸。
PROFIBUS-FMS :解決車間級(jí)通用性通信任務(wù),提供大量的通信服務(wù),完成中等傳輸速度的循環(huán)和非循環(huán)通信任務(wù),用于紡織工業(yè)、樓宇自動(dòng)化、電氣傳動(dòng)、傳感器和執(zhí)行器、可編程序控制器、低壓開關(guān)設(shè)備等一般自動(dòng)化控制。
PROFIBUS-PA專為過程自動(dòng)化設(shè)計(jì),標(biāo)準(zhǔn)的本質(zhì)安全的傳輸技術(shù),實(shí)現(xiàn)了IEC1158-2中規(guī)定的通信規(guī)程,用于對(duì)安全性要求高的場(chǎng)合及由總線供電的站點(diǎn)。
本設(shè)計(jì)中采用的是PROFIBUS-DP標(biāo)準(zhǔn),PROFIBUS-DP(或DP標(biāo)準(zhǔn))是由歐洲標(biāo)準(zhǔn)EN50170定義的一種遠(yuǎn)程I/O通信協(xié)議。DP表示分布式外圍設(shè)備,亦即遠(yuǎn)程I/O。PROFIBUS-DP還用到了應(yīng)用層接口(ALI),ALI將過程對(duì)象轉(zhuǎn)換為通信對(duì)象。
