USS通信協(xié)議功能
USS協(xié)議功能遵循主-從通信機(jī)制。主站根據(jù)USS站地址發(fā)請(qǐng)求報(bào)文訪問變頻器從站,從站返回應(yīng)答報(bào)文。USS總線上zui多可以連接31個(gè)變頻器,zui大波特率57.6kbit/s(對(duì)于S7-200,只能達(dá)到19.2kbit/s)。
如何建立USS通信?
硬件*:
– 三芯屏蔽電纜,用于連接變頻器和主站。
– USS通信必須連接在主站的接口0。
– 電纜依次連接變頻器直到zui后一個(gè)
– 變頻器連接端子8 (P+), 9 (N-) 和 10 (M/0V)。
– 為了保證通信穩(wěn)定,在總線上*個(gè)和zui后一個(gè)節(jié)點(diǎn)需要安裝終端電阻。主站上,在端子P+和N-上安裝終端電阻。
–在SINAMICS G110變頻器上,通過前端的DIP開關(guān)設(shè)置終端電阻連接。.
*關(guān)于 SIMATIC S7-200:
– 在S7-200側(cè),使用帶PROFIBUS連接頭的PROFIBUS電纜。
– 需要注意, 信號(hào)地和M (0V)端子已經(jīng)在內(nèi)部提供連接
– M (0V)端子應(yīng)和S7-200的電源M (0V)端子連接。不允許把總線電纜的屏蔽用作M(0V)。
– S7-200側(cè)的終端電阻通過PROFIBUS連接頭上的撥碼開關(guān)進(jìn)行設(shè)置。
– 更多詳細(xì)信息請(qǐng)參考S7-200系統(tǒng)手冊(cè)第11章。
如何調(diào)試和設(shè)置參數(shù)?
以和S7-200通信為例
西門子G110變頻器6SL3210-1KE21-3UB1
G110 參數(shù)*:
總線電纜連接完畢后,需要在變頻器中設(shè)置USS參數(shù)。
請(qǐng)?jiān)O(shè)置如下參數(shù):總線地址(P2011 = 0-31),波特率(P2010 = 7),報(bào)文長(zhǎng)度(P2012 = 2 / P2013 = 127)和報(bào)文監(jiān)控時(shí)間(P2014 = 根據(jù)現(xiàn)場(chǎng)系統(tǒng)要求設(shè)置)。以上操作可以通過選件操作面板或者免費(fèi)的軟件調(diào)試工具STARTER完成。STARTER軟件能夠在PC機(jī)上運(yùn)行,支持的系統(tǒng)為Windows NT/2000/XP Professional/Vista。如果通過PC連接組件連接,取下操作面板,在變頻器相同位置插上和面板相同尺寸的PC適配器即可。
*設(shè)置S7-200
S7-200 programming environment:
S7-200編程環(huán)境是使用Step7 Micro/WIN軟件。
同樣,請(qǐng)參考S7-200系統(tǒng)手冊(cè)第11章。
該軟件需要補(bǔ)充安裝一個(gè)協(xié)議庫,使其能通過USS協(xié)議控制變頻器。在軟件中新建一個(gè)項(xiàng)目,在指令-> 庫-> USS Protocol中調(diào)用USS通信的初始化和控制功能塊。
– 初始化功能塊"USS_INIT"設(shè)置S7-200的interface 0使用USS協(xié)議通信。
– 用控制模塊"USS_CTRL"發(fā)送控制字和速度設(shè)定值給變頻器。控制字的每一位——例如ON/OFF,反轉(zhuǎn),故障應(yīng)答——都是直接控制。其中,速度設(shè)定值用變頻器的參考頻率(參數(shù)P2000)進(jìn)行換算。
在應(yīng)答報(bào)文里,變頻器同時(shí)返回狀態(tài)字和變頻器實(shí)際運(yùn)行頻率。這樣使得已經(jīng)發(fā)生的報(bào)警和故障可以被識(shí)別,變頻器的運(yùn)行狀態(tài)可以被診斷。對(duì)這兩個(gè)功能塊編程,就可以獨(dú)立控制總線上的變頻器,允許他們運(yùn)行于不同的頻率設(shè)定值。
讀寫變頻器參數(shù):
編程軟件還提供了6個(gè)附加功能塊進(jìn)行讀寫操作——3個(gè)讀功能塊和3個(gè)寫功能塊。
注意:
在SINAMICS G110的參數(shù)表里有三種不同的參數(shù)顯示方式:WORD/U16, DOUBLE/U32 and REAL/float。用戶應(yīng)該根據(jù)不同的參數(shù)類型選擇相應(yīng)的功能塊。當(dāng)執(zhí)行一個(gè)寫操作時(shí),需要關(guān)注變頻器的運(yùn)行狀態(tài)。例如,有些參數(shù)諸如電機(jī)額定數(shù)據(jù)只能在調(diào)試模式下修改,而另外一些參數(shù),諸如斜坡上升時(shí)間(加速時(shí)間)甚至可以在變頻器運(yùn)行中修改。
SINAMICS G110 和USS 協(xié)議的可能應(yīng)用
a)生成一個(gè)程序塊,描述所有特定應(yīng)用的參數(shù)和值。總線地址使用一個(gè)S7-200計(jì)數(shù)器遞增,程序塊可以非常簡(jiǎn)單的訪問所有總線上的G110。如果在以后需要更改參數(shù),只要在程序塊里做相應(yīng)的簡(jiǎn)單修改就行,更改后的新值仍然可以寫入總線上的所有變頻器。通過寫操作,操作面板里存儲(chǔ)的參數(shù)也可以被裝載回變頻器里。如果參數(shù)被意外修改需要恢復(fù),或者用戶定制的參數(shù)集需要重新載入,這個(gè)功能就很必要了。
b) 通過附加S7-200模塊,擴(kuò)展通信能力,聯(lián)接到PROFIBUS, ASI-Bus, GSM, Ethernet(以太網(wǎng))或者Internet。
S7-200的通信擴(kuò)展選件允許Sinamics G110——作為Sinamics家族的zui小的變頻器——被集成到Siemens AG的“全集成自動(dòng)化"(TIA)概念之中。
c)使用具有WEB 服務(wù)器功能的IT 模塊將定制的Java小應(yīng)用程序保存到WEB 服務(wù)器,可以通過Ethernet(以太網(wǎng)) 或 Internet瀏覽這些網(wǎng)頁。就可以實(shí)現(xiàn)變頻器的交互控制,也可以實(shí)現(xiàn)參數(shù)的讀寫。
d) 在S7-200上評(píng)估變頻器運(yùn)行狀態(tài)。當(dāng)發(fā)生故障時(shí),相應(yīng)的故障號(hào)通過參數(shù)讀出。并可以通過GSM或者Internet()傳遞該故障。這樣用戶就能收到每個(gè)故障的詳細(xì)信息,并采取相應(yīng)的防范措施。
