毛海分享了智能汽車技術(shù)的發(fā)展趨勢(shì)，圍繞車聯(lián)網(wǎng)、自動(dòng)駕駛、共享出行、新能源四個(gè)方面做出了精彩的分享。其中具體分析解答了智能汽車產(chǎn)業(yè)，為何在今后發(fā)展趨勢(shì)中，將在達(dá)到的規(guī)模。 Ingo Clausse分享了如何現(xiàn)實(shí)和虛擬之間的融合，如何借助工業(yè)4.0這個(gè)愿景來(lái)成為的物聯(lián)網(wǎng)公司。 會(huì)上，王煒圍繞化的必要性，中小企業(yè)的合作的前景和空間，如何利用平臺(tái)的資源來(lái)實(shí)現(xiàn)的對(duì)接和溝通，如何建立自己的化的能力，如何通過(guò)合作共贏這五方面做出了精彩的演講。 Hermann Schaufler圍繞政策，市場(chǎng)，人才教育三方面如何對(duì)企業(yè)發(fā)展起到?jīng)Q定性作用，展開(kāi)了精彩的演講。建議大家這幾點(diǎn)要素，以合作機(jī)制雙贏。
) 臨時(shí)變量
臨時(shí)變量?jī)H在邏輯塊運(yùn)行時(shí)有效，邏輯塊結(jié)束時(shí)存儲(chǔ)臨時(shí)變量的內(nèi)存被操作系統(tǒng)另行 分配。S7將臨時(shí)變量定義在L堆棧中，L堆棧是為存儲(chǔ)邏輯塊的臨時(shí)變量而專設(shè)的。當(dāng)塊程序運(yùn)行時(shí)，在L堆棧中建立該塊的臨時(shí)變量，一旦塊執(zhí)行結(jié)束，堆棧重新分配，因而信息丟失。
邏輯塊局部數(shù)據(jù)的數(shù)據(jù)類型
在變量聲明表中，要明確局部數(shù)據(jù)的數(shù)據(jù)類型，這樣操作系統(tǒng)才能給變量分配確定的 存儲(chǔ)空間。局部數(shù)據(jù)可以是基本數(shù)據(jù)類型或復(fù)式數(shù)據(jù)類型，也可以是專門用于參數(shù)傳遞 的所謂的“參數(shù)類型”。參數(shù)類型包括定時(shí)器、計(jì)數(shù)器、塊的地址或指針等，見(jiàn)表5.2。表5.2 參數(shù)類型變量
參數(shù)類型 大 小 說(shuō) 明
定時(shí)器(Timer) 2 B 在功能塊中定義一個(gè)定時(shí)器形參，調(diào)用時(shí)賦予定時(shí)器實(shí)參
計(jì)數(shù)器(Counter) 2 B 在功能塊中定義一個(gè)計(jì)數(shù)器形參，調(diào)用時(shí)賦予計(jì)數(shù)器實(shí)參
塊：
Block_FB
Block_FC
Block_DB
Block_SDB 2 B 在功能塊中定義一個(gè)功能塊或數(shù)據(jù)塊形參變量，調(diào)用時(shí)給功能塊類或數(shù)據(jù)塊類形參賦予實(shí)際的功能塊或數(shù)據(jù)塊編號(hào)，如
FC 101、DB 42
指針(Pointer) 6 B 在功能塊中定義一個(gè)形參，該形參說(shuō)明的是內(nèi)存的地址指針。例如，調(diào)用時(shí)可給形參賦予實(shí)參P#M50.0，以訪問(wèn)內(nèi)存M50.0
ANY 10 B 當(dāng)實(shí)參的數(shù)據(jù)類型未知時(shí)，可以使用該類型
1) 定時(shí)器或計(jì)數(shù)器參數(shù)類型
在功能塊中定義一個(gè)定時(shí)器或計(jì)數(shù)器類型的形參，功能塊就能使用一個(gè)定時(shí)器或計(jì)數(shù)器，而不需明確具體的定時(shí)器或計(jì)數(shù)器，等到調(diào)用該功能塊時(shí)再確定定時(shí)器或計(jì)數(shù)器號(hào)。這使用戶程序能靈活性地分配和使用定時(shí)器或計(jì)數(shù)器。當(dāng)給定時(shí)器或計(jì)數(shù)器參數(shù)類型形參分配實(shí)參時(shí)，在“T”或“C”后跟一個(gè)有效整數(shù)，如T 100。
2) 塊參數(shù)類型
當(dāng)定義一個(gè)作為輸入輸出的塊時(shí)，參數(shù)聲明決定了塊的類型(FB、FC、DB等)。當(dāng)為塊參數(shù)類型形參分配實(shí)參時(shí)，可以使用物理地址，如FC 101，也可使用符號(hào)地址，如“valve
