MVME5110-2261自动化模块备件
已建立与DriveOPC的连接，但您无法看到任何驱动器。因此，您需要在尝试新连接之前断开OPC服务器。无论如何，当前没有任何PC指示的OPC服务器显示在标题栏中：另请参阅：连接到OPC服务器远程连接2.2远程连接由于DCOM涉及安全风险，我们不建议远程使用DriveOPC。如果要远程连接，请选择ABB。当出现“选择OPC服务器”对话框时，单击SMP。通过单击复选框“From a Remote PC”（从远程PC）来标记该复选框。在编辑字段中输入远程计算机的完全限定域名、IP地址或UNC名称，然后单击“确定”按钮：OPC Server 7-6 DriveWindow 2注意，根据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，这是因为建立了DCOM，并且DriveOPC标识了DDCS网络（除非因为另一个客户端而已在运行）。光标变为沙漏，状态栏通知您连接。如果远程计算机不存在、已关闭或未正确配置远程使用（RPC服务尚未启动），您将收到错误消息。如果不允许您访问远程计算机，您将收到一条错误消息。联机功能要求远程计算机连接到您的计算机。如果您的计算机保护不允许远程连接，DriveWindow可以连接，但联机功能不起作用。这表明您多次收到消息框，告知远程计算机无法使用联机功能（每个联机功能对应一个消息框）。如果对任何消息单击“否”，DriveWindow将立即停止尝试连接并保持脱机状态。OPC服务器驱动窗口2 7-7如果连接成功，则标题栏中会显示带有远程PC指示的当前OPC服务器：但是，请注意，即使远程OPC服务器无法使用通信硬件（例如，它当前由其他应用程序使用），也会进行连接。在这种情况下，DriveWindow不显示任何驱动器。另请参阅：连接到OPC服务器本地连接2.3脱机连接自版本2.10起，DriveWindow也可以通过脱机OPC脱机工作。您从未直接连接到OfflineOPC。当您恢复为脱机保存的工作空间或打开保存的图形文件（.dwt）时，DriveWindow将脱机。在脱机模式下，DriveWindow的外观和感觉就像它真的连接到了驱动器一样。您可以通过查看DriveWindow标题栏中的网络（OPC）服务器来区分联机和脱机模式。在脱机模式下，服务器名称为ABB。离线OPC，在线模式下为ABB。SMP（或其他一些真正的OPC服务器）。您可以通过断开OPC服务器或打开未保存为脱机的工作区来退出脱机模式。
Connection to the DriveOPC is established, however, but you cannot see any drives. So, you need to disconnect the OPC Server before trying a new connection. Anyway, the current OPC Server without any PC indication is shown in the title bar: See Also: Connecting to OPC Server Remote Connection 2.2 Remote Connection Because of security risks involved in DCOM, we do not recommend using DriveOPC remotely. If you want to connect remotely, select ABB.SMP by clicking it, when the Select OPC Server dialog box is presented. Mark the check field “From a Remote PC” by clicking it. Enter the fully qualified domain name, the IP address, or the UNC name of the remote computer into the edit field, and click the OK button: OPC Server 7-6 DriveWindow 2 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 of establishing the DCOM and because DriveOPC identifies the DDCS network (unless it is already running because of another client). The cursor turns to hour-glass and the status bar informs you about connecting. If the remote computer does not exist, it is down, or it is not configured properly for remote use (RPC service has not been started), you will get an error message. If you are not allowed to access the remote computer, you will get an error message. On-line features require that the remote computer connects to your computer. If your computer protection does not allow the remote to connect, DriveWindow is able to connect, but the on-line features do not function. Indication of this is that you get several times a message box telling that the remote computer cannot use on-line features (one message box for each on-line feature). If you click No to any of the messages, DriveWindow stops immediately trying to connect and stays offline. OPC Server DriveWindow 2 7-7 If connecting succeeded, the current OPC Server with the remote PC indication is shown in the title bar: However, note that connection is made even if the remote OPC Server is not able to use the communication hardware (it is currently used by some other application, for example). DriveWindow just does not show any drives in such a case. See Also: Connecting to OPC Server Local Connection 2.3 Off-line Connection Since version 2.10, DriveWindow is able to work also off-line by the help of OfflineOPC. You never connect directly to OfflineOPC. DriveWindow goes off-line when you either restore a workspace that was saved for off-line, or open a saved graph file (.dwt). In off-line mode the look and feel of DriveWindow are the same as if it was really connected to drives. You can differentiate between on-line and off-line mode by looking at the Network (OPC) server in the title bar of DriveWindow. In off-line mode, the server name is ABB.OfflineOPC, while in on-line mode it is ABB.SMP (or perhaps some other real OPC Server). You exit off-line mode by either disconnecting the OPC Server, or by opening a workspace that was not saved for off-line.
