因此，如果“MVI69E-MBS”是數(shù)字Source成員和字符串MVI69E-MBS成員，則在傳輸過程中會應(yīng)用數(shù)字到字符串的轉(zhuǎn)換。成員數(shù)組維度的總元素計數(shù)必須完全匹配。編輯傳輸列表傳輸列表可以在配置編輯器中創(chuàng)建、修改和刪除。在“配置編輯器”樹中選擇“傳輸列表”節(jié)點。內(nèi)容窗格將顯示一個包含所有傳輸列表的表。單擊“新建”創(chuàng)建一個新的傳輸列表。單擊“編輯”以編輯選定的傳輸列表。單擊DELETE（刪除）刪除選定的Transfer List（傳輸列表）。您也可以通過雙擊配置編輯器樹或內(nèi)容窗格中的傳輸列表來編輯傳輸列表。3.4.3轉(zhuǎn)移列表的執(zhí)行轉(zhuǎn)移列表中的轉(zhuǎn)移按序列號指定的順序執(zhí)行。選擇傳輸列表時，工具欄按鈕允許您按執(zhí)行順序向上或向下移動傳輸。如果您選擇一個MVI69E-MBS，然后單擊NEW（新建）按鈕，則會在所選Transfer之前添加新MVI69E-MBS。如果在未選擇轉(zhuǎn)賬的情況下添加新的轉(zhuǎn)賬，則新的轉(zhuǎn)賬將添加到列表的末尾。3.5觸發(fā)器觸發(fā)器定義數(shù)據(jù)何時從一個可編程控制器傳輸?shù)搅硪粋€。觸發(fā)器包含以下屬性。參數(shù)描述名稱唯一標(biāo)識觸發(fā)器的名稱。類型指定觸發(fā)器的激發(fā)方式。此值是固定的，不能修改。掃描周期對觸發(fā)器進(jìn)行評估的速率。條件觸發(fā)器觸發(fā)的條件。MVI69E-MBS條件可以是以下任意一種。
·“更改時傳輸”指示器如果啟用，則表示只要源數(shù)據(jù)發(fā)生更改，就會進(jìn)行傳輸。MVI69E-MBS如果選擇了“更改時傳輸”選項，則源數(shù)據(jù)自上次執(zhí)行傳輸列表以來沒有更改，并且源數(shù)據(jù)的存在時間不到10秒，則不會寫入傳輸目標(biāo)標(biāo)記。這種優(yōu)化可以提高寫入慢速網(wǎng)絡(luò)時的性能。在Source中指定字符串常量時，字符串常量必須以單引號開始和結(jié)束，并且不能包含單引號或雙引號作為要傳輸?shù)淖址囊徊糠帧?.4.1.傳輸期間的數(shù)據(jù)轉(zhuǎn)換當(dāng)來源的數(shù)據(jù)類型與目的地的數(shù)據(jù)類型不同時，來源將轉(zhuǎn)換為基本數(shù)據(jù)類型轉(zhuǎn)換規(guī)則的數(shù)據(jù)類型（第74頁）。將數(shù)據(jù)從一個數(shù)組傳輸?shù)搅硪粋€數(shù)組時，數(shù)組的維度必須在元素總數(shù)上匹配。如果需要，將根據(jù)“基本數(shù)據(jù)類型轉(zhuǎn)換規(guī)則”對所有成員進(jìn)行類型轉(zhuǎn)換。指定元素數(shù)大于1的PLC 5、SLC和MicroLogix標(biāo)記將被視為陣列。如果源和目標(biāo)是結(jié)構(gòu)（UDT），MVI69E-MBS則源和目標(biāo)結(jié)構(gòu)成員的名稱匹配。如果目標(biāo)中不存在源成員，則忽略該源成員。如果源中不存在MVI69E-MBS成員，則不允許進(jìn)行傳輸?；緮?shù)據(jù)類型轉(zhuǎn)換規(guī)則適用于匹配的成員，因此，如果“MVI69E-MBS”是數(shù)字源成員和字符串目標(biāo)成員，則在傳輸過程中應(yīng)用數(shù)字到字符串的轉(zhuǎn)換。成員數(shù)組維度的總元素計數(shù)必須完全匹配。
BAND (Bitwise AND) Fires when Compare Value 1 bitwise ANDed with Compare Value 2 is non zero. ELT, ELTE, EGT, EGTE, EEQ, ENEQ, EBAND These conditions are the same as the conditions above, except that these conditions are edge trigger conditions.MVI69E-MBS They only fire once when the condition evaluates to true. The trigger will fire again once, when the condition evaluates to false and then changes again to true.Parameter Description Tolerance Optional comparison Tolerance value (numeric constant). § Ignored for ALWAYS, NEVER, CHANGE, BAND, and EBAND conditions. § Used as hysteresis value for LT, LTE, GT, GTE, ELT, ELTE, EGT, and EGTE conditions. § Used as range for EQ, NEQ, EEQ, and ENEQ conditions. 3.5.1 Hysteresis Example ·MVI69E-MBS Compare Value 1 = Tag1 · Condition = EGT · Compare Value 2 = 212.0 · Tolerance = 12.0 ·MVI69E-MBS Trigger fires once when Tag1 > 212.0.
If you add a new Transfer while no Transfers are selected, the new Transfer will be added to the end of the list.MVI69E-MBS 3.5 Triggers Triggers define when the data is transferred from one programmable controller to another. A Trigger contains the following attributes. Parameter Description Name The Name that uniquely identifies the Trigger. Type Specifies how the Trigger fires. This value is fixed and cannot be modified. Scan Period The rate at which the Trigger will be evaluated. Condition The Condition under which the Trigger will fire. Condition can be any of the following. Parameter Description ALWAYS Always fires. NEVER Never fires. CHANGE Fires on change of state. LT Fires when Compare Value 1 < Compare Value 2. LTE Fires when Compare Value 1 <= Compare Value 2. GT Fires when Compare Value 1 > Compare Value 2. GTE Fires when Compare Value 1 >= Compare Value 2. EQ Fires when Compare Value 1 = Compare Value 2.MVI69E-MBS NEQ Fires when Compare Value 1 <> Compare Value 2.MVI69E-MBS
so, if "MVI69E-MBS" is a numeric Source member and a string Destination member, a number to string conversion is applied during the transfer. Member array dimension total element counts must match exactly.Editing Transfer Lists Transfer Lists can be created, modified, and deleted in the Configuration Editor. Select the Transfer Lists node in the Configuration Editor tree. The content pane will display a table containing all of the Transfer Lists. Click NEW to create a new Transfer List. Click EDIT to edit the selected Transfer List. Click DELETE to delete the selected Transfer List. You can also edit a Transfer List by double clicking on the Transfer List in the Configuration Editor tree or in the content pane. MVI69E-MBSExecution of Transfer Lists The Transfers in the Transfer List are executed in the order specified by the Sequence Number. When you select a Transfer List, the toolbar buttons allow you to move the Transfers up or down in the order of execution. If you select a Transfer and then click the NEW button, the new Transfer will be added BEFORE the selected Transfer.
