为了加深对配置过程的理解，下面列出了有关 mapp Vision HMI 应用程序如何工作的信息。
•当摄像机工作时，不允许关闭页面或通过刷新浏览器更新页面。mapp Vision HMI 应用程序可使用 HMI 应用程序中的按钮和下拉框进行导航。
•在 mapp Vision HMI 应用程序中，会话开始于选择视觉组件并建立连接，结束于再次退出。在会话开始和结束时，视觉组件上定义的视觉应用程序将从 PLC 加载到摄像机。有关详细信息，请参阅保存、加载或删除视觉应用程序。
•在 HMI 应用程序中为循环变量输入的值仅在 HMI 会话期间有效，不会被 mapp Vision 保存。这些值可在用户应用程序中通过过程变量进行设置。
•HMI 应用程序中的视觉功能视图代表摄像机对该特定视觉功能 (VF) 实例的视图。不过，哪些信息可用取决于视觉应用程序的配置。在人机界面应用程序中，只能计算并显示有线的结果。
•mapp Vision HMI 应用程序中的输入和输出值只有在图像采集、执行或特定命令时才会更新。特定命令包括教导模型或在退出编辑模式时应用执行 ROI。
•下拉菜单包含该选项在 I/O 界面上的数值（方括号内）。
•mapp Vision HMI 应用程序中显示的摄像机图像采用 JPEG 格式压缩。图像处理和视觉功能配置总是基于未压缩的图像在摄像机上执行。
•使用 mapp Vision HMI 应用程序进行配置时
•使用配置 HMI 应用程序（mapp Vision HMI 应用程序）需要 mapp View 5.10.1 或更高版本。
•要使用 mapp Vision HMI 应用程序，必须将 mapp View 配置为连接到 "默认 OPC UA 服务器"（请参阅配置 OPC UA 服务器连接）。
•要使用 mapp Vision HMI 应用程序，必须在<图像采集>/<采集配置>/<触发源>下的视觉应用程序中选择 "软件"。
•在 mapp Vision HMI 应用程序中配置期间，强烈建议不要以任何其他方式并行操作摄像机（I/O 映射、应用程序）。
•每个 PLC 只能打开和操作一个 mapp Vision HMI 应用程序会话。
•对于 mapp Vision HMI 应用程序，mapp View 设置（文件 .mappviewcfg 中）必须在服务器配置中将协议设置为 "HTTP "或 "HTTP + HTTPS"，端口号必须为 81。默认设置符合这些条件。
•必须为 mapp Vision 使用的端口 81 和 15080 创建一个 B&R 代理，以便通过安全远程维护 SiteManager（参见SiteManager）进行远程维护。
•mapp Vision HMI 应用程序不支持动态线路传感器（参见线路传感器模式）。线路传感器可以配置为静态配置，或者必须在 I/O 接口上指定有效值（CyclicLineScanNettime和CyclicLineScanPeriod）。
In order to provide deeper understanding of the configuration processes, the list below contains information about how the mapp Vision HMI application works.
•While the camera is busy, the page is not permitted to be closed or updated via browser refresh. The mapp Vision HMI application is designed to be navigated using the buttons and drop-down boxes available in the HMI application.
•A session in the mapp Vision HMI application begins by selecting the vision component and establishing the connection ends when it is exited again. At the beginning and end of the session, the vision application defined on the vision component is loaded from the PLC to the camera. For additional information, see Saving, loading or deleting the vision application.
•Values that are entered in the HMI application for cyclic variables are only valid during the HMI session; they are not persisted by mapp Vision. The values can be set in a user application via process variables.
•The view of a vision function in the HMI application represents the camera's view of that specific vision function (VF) instance. Which information is available depends on the configuration of the vision application, however. Only the results that are wired are calculated and can be displayed in the HMI application.
•The values of inputs and outputs in the mapp Vision HMI application are updated only in the event of an image acquisition, Execute or specific commands. Specific commands include teaching-in models or applying the Execution ROI when exiting edit mode.
•Drop-down menus contain the value (in square brackets) that is present on the I/O interface for this option.
•The displayed camera image in the mapp Vision HMI application is compressed with JPEG. Image processing and configuration of the vision functions is always performed on the camera based on the uncompressed image.
•For configuration with the mapp Vision HMI application
•mapp View 5.10.1 or higher is required to use the configuration HMI application (mapp Vision HMI application).
•To use the mapp Vision HMI application, mapp View must be configured to connect to the "default OPC UA server" (see Configuring the OPC UA server connections ).
•To use the mapp Vision HMI application, "Software" must be selected in the vision application under <Image acquisition> / <Acquisition configuration> / <TriggerSource>.
•During configuration in the mapp Vision HMI application, it is strongly recommended not to operate the camera in parallel in any other way (I/O mapping, application).
•Only one session of the mapp Vision HMI application can be opened and operated per PLC.
•For the mapp Vision HMI application, mapp View settings (in file .mappviewcfg) must be set to "HTTP" or "HTTP + HTTPS" for the protocol in the server configuration, and the port number must be 81. The default settings meet these conditions.
•A B&R agent must be created for the ports used by mapp Vision, 81 and 15080, for remote maintenance via the Secure Remote Maintenance SiteManager (see SiteManager).
•The dynamic line sensor (see LinesensorMode) is not supported on the mapp Vision HMI application. The line sensor can be configured as static for the configuration, or valid values must be specified on the I/O interface (CyclicLineScanNettime and CyclicLineScanPeriod).
