現(xiàn)場(chǎng)總線PROFIBUS-DP
PROFIBUS-DP是經(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)和分布式I/O站以及現(xiàn)場(chǎng)設(shè)備之間的通信而設(shè)計(jì),使用PROFIBUS-DP模塊可取代價(jià)格昂貴的24V或0到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,其主要特點(diǎn)是zui小化的響應(yīng)時(shí)間,高抗干擾性。
PROFIBUS-DP使用物理層和數(shù)據(jù)鏈路層,這種精簡(jiǎn)的結(jié)構(gòu)保證了數(shù)據(jù)的高速傳輸,特別適合PLC與現(xiàn)場(chǎng)分散的I/O設(shè)備之間的通信。直接數(shù)據(jù)鏈路映像程序DDLM提供對(duì)數(shù)據(jù)鏈路層的訪問。用戶接口規(guī)定了設(shè)備的應(yīng)用功能、PROFIBUS-DP系統(tǒng)和設(shè)備的行為特性。PROFIBUS-DP特別適合于PLC主站與從站之間的主從方式,以及這兩種方式的混合。
PROFIBUS-DP用于設(shè)備級(jí)的高速數(shù)據(jù)傳送,*控制器通過高速串行線同分散的現(xiàn)場(chǎng)設(shè)備進(jìn)行通信,多數(shù)數(shù)據(jù)交換是周期性的,除此之外,智能化現(xiàn)場(chǎng)設(shè)備還需要非周期性通信,以進(jìn)行配置、診斷和報(bào)警處理。
*控制器周期地讀取從設(shè)備的輸入信息并周期地向從設(shè)備發(fā)送輸出信息,總線循環(huán)時(shí)間必須要比*控制器的程序循環(huán)時(shí)間短。除周期性用戶數(shù)據(jù)傳輸外,PROFIBUS-DP還提供了強(qiáng)有力的診斷、保護(hù)、組態(tài)和配置功能,數(shù)據(jù)通信是由主站和從站進(jìn)行監(jiān)控的,具有同步和鎖定功能。主站和從站的數(shù)據(jù)分三個(gè)階段:參數(shù)化、組態(tài)和數(shù)據(jù)交換進(jìn)行周期化傳送。
