产品内容介绍
PM866-2单元控制系统
导入附加指令
1在Controller Organization（控制器组织）窗口中，展开TASKS文件夹和子文件夹，直到已访问MAINPROGRAM文件夹。
2在MAINPROGRAM文件夹中，双击打开MAINROUTINE梯形图。
3在新例程中选择一个空梯级，然后单击鼠标右键打开快捷菜单。在快捷菜单上，选择IMPORT RUNG。
4导航到PC上保存附加指令的位置（适用于例如，我的文档或桌面）。
选择MVI56ESIE_ADDON_RUNG_V1_X。L5X文件。此操作将打开“导入配置”对话框。
单击标记参考将显示将创建的控制器标记。
5如果模块正在不同的插槽（或远程机架）中使用，请选择正确的定义模块路径的连接输入和输出变量。
如果模块位于本地机架的插槽1中，不需要执行此步骤。调整输入和输出阵列大小
模块的内部数据库分为两个用户可配置区域：
读取数据
写入数据
读取数据从模块移动到处理器，而写入数据从处理器移动到模块。
MVI56E-SIE附加指令梯级配置为600个读数据寄存器和600个写入数据寄存器，这对于大多数应用程序来说足够了。
然而，你可以配置这些数据区域的大小以满足应用程序的需要。
要点：
由于模块一次以200个寄存器的块为单位分页数据，您应该配置200个寄存器的倍数中的用户数据区域。
警告：当阵列大小更改时，RSLogix可能会将SIE标记重置为零。
为了避免数据丢失继续之前，请确保保存设置。
将电脑连接到ControlLogix处理器有几种方法可以在您的电脑和ControlLogix处理器。
以下步骤显示了如何建立通信通过串行接口。不强制使用处理器的串行接口。
处理器可以通过系统有关其他方面的信息，请参阅罗克韦尔自动化文档连接方法。
1将电缆的直角连接器端连接到控制器通信端口。
2将电缆的直连接器端连接到计算机上的串行端口。
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.
