MVME51105E-2261工控模块系统备件
打开为脱机保存的图形文件或工作区将连接到OfflineOPC，而不是真正的OPC服务器。请注意，某些DriveWindow操作需要重新启动驱动器。重新启动DriveWindow启动的驱动器会导致OPC服务器的内部断开和重新连接。当DriveWindow启动时，系统会要求您连接到OPC服务器，除非您通过双击NT Explorer中的文件启动DriveWindow（例如）。如果要恢复工作区，请单击“取消”按钮，然后打开工作区。如果您要通过本地DriveOPC处理系统软件，我们建议您不要连接，而是单击“取消”按钮。如果您没有连接到OPC服务器，您可以通过从“网络”菜单中选择“网络服务器”或按Ctrl+N请求连接。在上下文菜单中也可以找到相同的命令，当浏览树窗格为空且尚未连接时，可以通过在浏览树窗格上单击鼠标右键获得该命令。请注意，如果您已经连接到OPC服务器，则必须首先断开当前服务器的连接。切勿直接连接到OfflineOPC。出现选择OPC服务器对话框：OPC服务器7-4 DriveWindow 2如果列出了多个OPC服务器，请选择ABB。单击SMP。如何继续，取决于您是要连接到本地还是远程OPC服务器。另请参阅：什么是OPC服务器连接到DDCS网络本地连接远程连接2.1本地连接如果您想本地连接，请选择ABB。当出现“选择OPC服务器”对话框时，单击SMP，然后单击“确定”按钮：注意，根据您的操作系统及其配置方式，也可以“远程”连接到本地服务器（EXE）。通常，远程连接到\\localhost或127.0.0.1实际上连接到同一台PC中的本地服务器。连接需要一段时间，因为DriveOPC标识DDCS网络。光标变为沙漏，状态栏通知您连接。如果您的本地PC上没有安装DDCS硬件，则通信库会给您一条错误消息。OPC服务器DriveWindow 2 7-5然而，在这种情况下，也会建立到DriveOPC的连接，但当然，您看不到任何驱动器。因此，您需要在尝试新连接之前断开OPC服务器。自DriveWindow 2.01版（DriveOPC 2.02版）起，如果另一个应用程序已经在使用DDCS硬件，则通信库会向您显示错误消息。在旧版本中，或者如果DriveOPC配置为远程使用，则不会显示任何消息。
Opening a graph file or a workspace saved for offline connects to OfflineOPC instead of a real OPC Server. Note that some DriveWindow operations require restarting of a drive. Restarting a drive initiated by DriveWindow does an internal disconnecting and reconnecting of the OPC Server. You are asked to connect to an OPC Server when DriveWindow is starting, unless you started DriveWindow by double clicking a file in NT Explorer (for example). If you are going to restore a workspace, click the Cancel button, and then open the workspace. If you are going to handle system software through the local DriveOPC, we recommend that you do not connect, but click the Cancel button If you are not connected to an OPC Server, you can request to be connected by selecting Network Servers from the Network menu or by pressing Ctrl+N. The same command can be found in the context menu, which you get by clicking with the right mouse button on the browse tree pane when it is empty and you are not yet connected. Note that if you already have connected to an OPC Server, you have to disconnect the current server first. Never connect directly to OfflineOPC. A Select OPC Server dialog box is presented: OPC Server 7-4 DriveWindow 2 If there are several OPC Servers listed, select ABB.SMP by clicking it. How to proceed, depends on, whether you want to connect to the local or a remote OPC Server. See Also: What is OPC Server Connecting to DDCS Network Local Connection Remote Connection 2.1 Local Connection If you want to connect locally, select ABB.SMP by clicking it, and click the OK button, when the Select OPC Server dialog box is presented: Note that depending on your operating system and how it is configured, it may also be possible to connect to the local server (EXE) “remotely”. Typically, connecting remotely to \\localhost or 127.0.0.1, actually connects to the local server in the same PC. Connecting takes for a while, because DriveOPC identifies the DDCS network. The cursor turns to hour-glass and the status bar informs you about connecting. If you do not have DDCS hardware installed in your local PC, the communication library gives you an error message. OPC Server DriveWindow 2 7-5 However, connection to the DriveOPC is established also in this case, but, of course, you cannot see any drives. So, you need to disconnect the OPC Server before trying a new connection. Since version 2.01 of DriveWindow (version 2.02 of DriveOPC), if another application program is already using the DDCS hardware, the communication library gives you an error message. In older versions, or if DriveOPC is configured to be used remotely, no message is shown.
