PM866-2單元控制系統(tǒng)
導入附加指令
1在Controller Organization（控制器組織）窗口中，展開TASKS文件夾和子文件夾，直到已訪問MAINPROGRAM文件夾。
2在MAINPROGRAM文件夾中，雙擊打開MAINROUTINE梯形圖。
3在新例程中選擇一個空梯級，然后單擊鼠標右鍵打開快捷菜單。在快捷菜單上，選擇IMPORT RUNG。
4導航到PC上保存附加指令的位置（適用于例如，我的文檔或桌面）。
選擇MVI56ESIE_ADDON_RUNG_V1_X。L5X文件。此操作將打開“導入配置”對話框。
單擊標記參考將顯示將創(chuàng)建的控制器標記。
5如果模塊正在不同的插槽（或遠程機架）中使用，請選擇正確的定義模塊路徑的連接輸入和輸出變量。
如果模塊位于本地機架的插槽1中，不需要執(zhí)行此步驟。調(diào)整輸入和輸出陣列大小
模塊的內(nèi)部數(shù)據(jù)庫分為兩個用戶可配置區(qū)域：
? 讀取數(shù)據(jù)
? 寫入數(shù)據(jù)
讀取數(shù)據(jù)從模塊移動到處理器，而寫入數(shù)據(jù)從處理器移動到模塊。
MVI56E-SIE附加指令梯級配置為600個讀數(shù)據(jù)寄存器和600個寫入數(shù)據(jù)寄存器，這對于大多數(shù)應用程序來說足夠了。
然而，你可以配置這些數(shù)據(jù)區(qū)域的大小以滿足應用程序的需要。
要點：
由于模塊一次以200個寄存器的塊為單位分頁數(shù)據(jù)，您應該配置200個寄存器的倍數(shù)中的用戶數(shù)據(jù)區(qū)域。
警告：當陣列大小更改時，RSLogix可能會將SIE標記重置為零。
為了避免數(shù)據(jù)丟失繼續(xù)之前，請確保保存設置。
將電腦連接到ControlLogix處理器有幾種方法可以在您的電腦和ControlLogix處理器。
以下步驟顯示了如何建立通信通過串行接口。不強制使用處理器的串行接口。
處理器可以通過系統(tǒng)有關其他方面的信息，請參閱羅克韋爾自動化文檔連接方法。
1將電纜的直角連接器端連接到控制器通信端口。
2將電纜的直連接器端連接到計算機上的串行端口。
Importing the Add-On Instruction
1 In the Controller Organization window, expand the TASKS folder and subfolder until the MAINPROGRAM folder is reached. 2 In the MAINPROGRAM folder, double-click to open the MAINROUTINE ladder. 3 Select an empty rung in the new routine, and then click the right mouse button to open a shortcut menu. On the shortcut menu, choose IMPORT RUNG.4 Navigate to the location on the PC where the Add-On Instruction was saved (for example, My Documents or Desktop). Select the MVI56ESIE_ADDON_RUNG_V1_X.L5X file.This action opens the Import Configuration dialog box. Clicking on Tags Reference will show the controller tags that will be created.5 If the module is being used in a different slot (or remote rack), select the correct connection input and output variables that define the path to the module. If the module is located in Slot 1 of the local rack, this step is not required.
Adjusting the Input and Output Array Sizes
The module’s internal database is divided into two user-configurable areas: ? Read Data ? Write Data The Read Data is moved from the module to the processor, while the Write Data is moved from the processor to the module. The MVI56E-SIE Add-On Instruction rung is configured for 600 registers of Read Data and 600 registers of Write Data, which is sufficient for most applications. However, you can configure the sizes of these data areas to meet the needs of your application. Important: Because the module pages data in blocks of 200 registers at a time, you should configure your user data areas in multiples of 200 registers. Caution: When the array size is changed, RSLogix may reset the SIE tags to zero. To avoid data loss, be sure to save the settings before continuing.
Connecting Your PC to the ControlLogix Processor
There are several ways to establish communication between your PC and the ControlLogix processor. The following steps show how to establish communication through the serial interface. It is not mandatory to use the processor's serial interface. The processor may be accessed through whatever network interface is available on the system. Refer to the Rockwell Automation documentation for information on other connection methods. 1 Connect the right-angle connector end of the cable to the controller at the communications port. 2 Connect the straight connector end of the cable to the serial port on the computer.
