集成在 SIMATIC PCS 7 中的 S7-300 / S7-400 打包裝置

應(yīng)用程序目的
應(yīng)用程序的目標(biāo)是描述必須如何通過 WinCC (TIA 應(yīng)用程序) 創(chuàng)建一個 S7 程序，以便日后可以集成到 PCS 7 系統(tǒng)中。

例如，用于機械制造商打包裝置的 STEP 7 / WinCC 應(yīng)用程序，一般都創(chuàng)建為 TIA 應(yīng)用程序。這些應(yīng)用程序中有一部分日后必定會集成到生產(chǎn)設(shè)備的控制系統(tǒng)中。為此，必須在創(chuàng)建這樣的應(yīng)用程序時就已考慮到某些組態(tài)規(guī)范。 

此外，該文檔還描述需求和必要的組態(tài)步驟，以便創(chuàng)建一個含有滿足集成到 PCS 7 系統(tǒng)要求的 WinCC flexible 應(yīng)用程序的 S7-300/S7-400 項目。該文檔以分步說明的方式描述了必要的方法。

主要內(nèi)容
本文檔中主要描述了下列幾點：

• 適用的編輯器 (AWL，SCL，CFC)
• 選擇該系統(tǒng)的條件
• OS 傳送措施
• WinCC flexible 連接到 CFC 程序
• 整合 TIA 項目和 PCS 7

有效性
… 對版本為 V6.0 到 V7.1 的 PCS 7 有效

例如，我們要讀取的數(shù)值為1、2、4、7、8，我至少要選擇1個單位的分辨率，選擇2個單位的分辨率是顯然不行的，因為我們讀出了1這個數(shù)值，則2是讀不出來的，在選擇1個單位分辨率的基礎(chǔ)上，我們讀出來的1與真實的1的誤差就是精度。機床上的數(shù)控系統(tǒng)對于直光柵是有分辨率的設(shè)定的，需要讀取的數(shù)值間隔小于分辨率，機床就有可能會抖動或出錯等。 對于式帶增量信號編碼器，能夠精確的保持串行傳輸?shù)奈恢弥蹬c增量值同步，值確切的對應(yīng)一個增量信號，位置值一定在一個增量信號的正弦周期之內(nèi)。如13位式，帶512線的增量信號，位置間隔158秒，若要讀取兩個碼盤位置中間的一個位置是不合適的，但是，我們可以通過對其所帶的1Vpp增量信號進行細(xì)分，如細(xì)分100倍，則相當(dāng)于在兩個位置之間又引入了幾個細(xì)分后的位置，我們可以在位置值的基礎(chǔ)上，通過計算細(xì)分后的增量脈沖數(shù)而讀取兩個位置之間的一個位置值，如：512線細(xì)分100倍，位置1數(shù)值是0，位置2數(shù)值是158，則讀取這兩個位置間的位置可以在位置1：數(shù)值0的基礎(chǔ)上多出一個脈沖則是25，兩個則是25x2=50……但是，帶增量信號的式編碼器本身是不帶細(xì)分的，這就要求用戶能自行的對增量信號進行細(xì)分處理。

如何使用預(yù)定義數(shù)據(jù)類型UDT1“FILE_DB_HEADER”進行S7-300和S7-400的FTP通信？

S7-300和S7-400可以通過Advanced/IT以太網(wǎng)CP卡使用多種FTP功能?？梢栽谝韵氯N模式中選擇：

• FTP客戶端：
  通過“FTP_CMD”指令塊觸發(fā)FTP指令。CP卡訪問遠程FTP服務(wù)器。
• 使用CPU數(shù)據(jù)的FTP服務(wù)器：
  遠程FTP客戶端訪問CP，CP將文件訪問轉(zhuǎn)發(fā)到CPU。例如，一個文件被存儲在CP中，之后CP會將文件內(nèi)容保存在CPU中的相應(yīng)數(shù)據(jù)塊中。
• 使用CP文件系統(tǒng)的FTP服務(wù)器：
  遠程FTP客戶端訪問CP。文件只被存儲在CP的文件系統(tǒng)中而不會轉(zhuǎn)發(fā)到CPU。

除了zui后一個模式之外的所有模式必須使用CPU中的一個結(jié)構(gòu)的數(shù)據(jù)塊。在每個文件DB的開始必須使用預(yù)定義的數(shù)據(jù)類型UDT1 “FILE_DB_HEADER”，該數(shù)據(jù)類型可以從SIMATIC_NET_CP指令庫中找到。

預(yù)定義的數(shù)據(jù)類型UDT1 “FILE_DB_HEADER”的結(jié)構(gòu)　
表格 01列出了如下內(nèi)容：

• 預(yù)定義的數(shù)據(jù)類型UDT1 “FILE_DB_HEADER”的參數(shù)。
• 如何使用這些參數(shù)。
• 這些參數(shù)如何通過系統(tǒng)自動設(shè)置。

Chen Piao was 16 years old from the river to the wind in the wind, in the more developed early, strong, brave and decisive character. Small fire wheel down the river, Chen float side boat side, and came to the cab Jenkins chat. They looked at the river, sometimes a few finless porpoise playing in the water, not well-known white birds around the small fire wheel upside down, the distant waves shining bright light shining in the sun, the two sides of Castle Peak and small fire round to go, this is really like a dream, everything is so natural, so harmony. Jenkins enjoyed the beautiful natural scenery, mesmerizing: "ah, this place is beautiful." Chen Piao reminded him: "you are not to experience the evil beach to stimulate feelings of it, we have to walk a few minutes later!" "Then I can't miss the golden opportunity or go to the deck to enjoy this wonderful experience."!" Said Jenkins, walking from the cab to the deck of the small fire wheel, and looking ahead. Pibozhanlang small fire wheel rapidly toward the beach for evil, Captain Chen Piao two big eyes staring at a bayonet bayonet practice of warriors, fast to the devil beach, he put the bow in front of the big black lagoon, fast marching. Standing on the deck of the Jenkins suddenly found the little steamer to the field away, he was scared, shouted: "my God, are you crazy? We're going to hit the reef......" Chen drift unmoved, a small fire wheel is still rapid towards the field for the small fire wheel to hit a big moment field, desperate Jenkins decided to throw the helve after the hatchet, he took a deep breath, suddenly from the wheel of fire on the deck of the jump to the big black lagoon, at the last moment, a small fire wheel bow swing smoothly passed large black lagoon. Originally, Chen Piaogang only action is intentional, which he had sailed a beach evil trick, every evil Big Black Lagoon Beach, he always dare to ship in front of a large open field in the field, from the big stone two feet away left the bow, the ship with the waves rushed to the big black on the reef and back to the boat, so that the ship hit a reef will not only through the place near the great black lagoon. Chen drift and use this method too large field hundreds of times, no one missed. Chen Piao looked at Jenkins on the rocks and was stunned: "Jenkins!"......" In the field of Jenkins also desperay shouted: "Mr. Chen, please help me......" The small fire wheeled relentlessly down the stream, where no ship was coming. For five days, passing ships will see a blond blue eyed foreigner standing in the field on the waving to them for help, but no one can save him. Five days later, Jenkins, standing on the rocks, was gone. Because of the death agreement, Chen Piao finally failed to get into court. The rain in the morning, Chen Piao in a grave soil put offerings, murmured: "brother, brother Jenkins died, give you revenge!" Originally, Jenkins is nominally a life-saving doctor, is actually a guy with a commit all sorts, diplomatic immunity, not only the bully, also open to Chongqing to sell opium. Some treat patients in his hospital, he secretly took western medicine to give them doping opium drugs, cure disease, but also addicted, then go, had to go to Jenkins there to buy expensive opium, lots of shining white silver flowed into Jenkins's pocket. Caughtsmokeaddiction people. Is very poor, often broken up, but because Jenkins is a foreigner, and with local authorities, local officials will wink.
