西門子PLC與ABB變頻器之間的現(xiàn)場總線通訊技術(shù)
技術(shù)分類:軟件與信息集成 發(fā)表時間：2007-02-15
PLC主程序中調(diào)用兩個系統(tǒng)功能塊SFC14和SFC15來讀寫這些數(shù)據(jù)，實現(xiàn)到變頻器的通信控制;
(3) 在主PLC程序中建立一個數(shù)據(jù)塊，用于于變頻器的數(shù)據(jù)通信;建立一變量表，用于觀測實時通訊效果。
?????? 4? 變頻器運行設(shè)置
?????? 變頻器與PLC應(yīng)用Profibus-DP現(xiàn)場總線連成網(wǎng)絡(luò)后，除在PLC自動化系統(tǒng)中進行編程外，在每個變頻器上也要進行適當?shù)膮?shù)設(shè)置。
通訊電纜聯(lián)接后，啟動變頻器，完成對變頻器通訊參數(shù)的
?????? 4.1? 基本設(shè)置。
(1) 51.01—模塊類型，本參數(shù)顯示由傳動裝置探測到的模塊型號。其參數(shù)值用戶不可調(diào)整。如果本參數(shù)沒有定義，則不能在模塊與傳動之間建立通訊。
(2) 51.02—本參數(shù)選擇通訊協(xié)議，“0”為選擇Profibus-DP通訊協(xié)議。
(3) 51.03—本參數(shù)為Profibu
s連接選擇的PPO類型，“3”為PPO4，但變頻器上的PPO類型應(yīng)與PLC上組態(tài)的PPO類型一致。
(4) 51.04—本參數(shù)用于定義設(shè)備地址號，即變頻器的站點地址，在Profibus連路上的每一臺設(shè)備都必須有一個單獨的地址。本次設(shè)計中兩臺變頻器分別為2、3號站。[1]
?????? 4.2? 過程參數(shù)的連接
?????? 過程參數(shù)互聯(lián)完成NPBA-12雙端口RAM連接器與變頻器相應(yīng)參數(shù)的定義和連接，包括主站(PLC)到變頻器的連接和變頻器到主站(PLC)的連接兩部分。在變頻器上設(shè)定下列連接參數(shù)。
(1) 從PLC發(fā)送到傳動裝置變頻器的PZD值
l PZD1—控制字，如變頻器的啟動使能、停止、急停等控制命令;??
l PZD2—變頻器的頻率設(shè)定值。
(2) 從傳動裝置變頻器發(fā)送到PLC的PZD值
l PZD1—狀態(tài)字,如報警、故障等變頻器運行狀態(tài);
l PZD2—變頻器的速度實際值、電流實際值等。
?????? 5? 結(jié)束語
?????? 變頻器控制系統(tǒng)采用了Profibus-DP現(xiàn)場總線控制模式后，不但整個系統(tǒng)可靠性強，操作簡便，而且可根據(jù)工藝需要進行靈活的功能修改。該系統(tǒng)在濟鋼鮑德彩板有限公司應(yīng)用以后，運行效果良好，為今后總公司的自動化設(shè)備(不同廠家的網(wǎng)絡(luò)通訊)提供了一個成功典范。
