WebVisu

什么是WEBVISU？

当运行装有WebVisu的机器时，您可以通过网页浏览器远程查看和操作机器的人机界面。
CODESYS WebVisu 3.5 可与 Epec 6107 显示器、Epec 6112 显示器和 Epec 6200 远程访问单元一起使用。

为什么WEBVISU如此实用？

• 它可以帮助技术支持或服务团队通过远程桌面访问现场机器的人机界面进行查看诊断。
• 它可以帮助服务和研发工程师轻松创建服务和诊断门户，而不需要额外搭建任何网络服务器。
• 服务人员可以在机器周边移动、执行相关维护调试服务的同时，通过平板电脑或智能手机直接连接机器的用户界面（可通过内置WLAN接入点功能的Epec 6000系列单元实现）。
• WebVisu 操作简便，无需设置任何 Web 服务器。
• 无需为平板电脑/智能手机定制开发任何应用程序，任何带有标准网络浏览器的设备均可使用。

WebVisu是一款理想的按需启动远程服务门户的解决方案。当机器不在线不需要访问数据，或者当不需要同时查看多台机器的可视化数据时，您可以选择不启用WebVisu。

若机器不需要安装本地人机用户界面，但偶尔也会需要对机器进行调整、诊断等操作时，配备有WLAN和WebVisu的Epec 6200 远程接入单元便是一个完美的解决方案。操作人员可以将他的智能手机作为人机界面使用，对机器完成需要的设置。

为什么选择WebVisu？

就远程诊断而言，比起将所有诊断数据上传到某个云服务器进行可视化分析记录，使用 WebVisu 具有以下优势：

• 首先，您可以使用可能具备相同或类似屏幕/功能的现有本地用户界面，而无需创建任何新的用户界面。
• 此外，您无需将诊断数据发送到服务器进行可视化分析诊断，而可以直接访问机器，从而最大限度地减少延迟、做到对数据的实时可视化分析诊断。
• WebVisu 不仅提供远程桌面视图，它还能帮助您远程操作人机交互界面。你可以在不同窗口之间进行导航，也可以执行与本地操作人员相同的交互操作。此外，多个远程用户还能同时登陆并通过各自的用户界面进行操作。
• WebVisu为您的服务团队提供了经济高效的远程诊断门户。只需在原有Epec 6000系列单元产品价格上再支付一小笔一次性许可费，您即可拥有WebVisu。

What?

When a machine with WebVisu is running, you are able to see and operate the machine’s HMI remotely using a web browser.

CODESYS WebVisu 3.5 can be used with Epec 6107 Display unit, Epec 6112 Display unit and Epec 6200 Remote Access Unit.

WebVisu is useful because:

• It can provide a remote desktop view of the local HMI to help the work of techsupport or service team
• It can be used to create service and diagnostics portals easily for service and R&D engineers without setting up any web servers
• A service person can move around the machine performing needed service activities while using the machine HMI with a tablet or smartphone at the same time (Epec 6000 series unit’s built-in WLAN access point feature enables this)
• Using WebVisu is easy, there is no need to setup any web servers
• There is no need to develop any App for the tablet/smartphone, any device with a standard web browser is suitable.

WebVisu is an ideal solution for on-demand remote service portal if there is no need to access data while machine is not online or to visualize data simultaneously from several machines.

If there is no need for local HMI in the machine, but still some adjustment, diagnostics, etc. need to be done occasionally, Epec 6200 Remote Access Unit with WLAN and WebVisu is a convenient solution, since the operator can use his smartphone as a HMI when needed.

Why?

For remote diagnostics purposes, using WebVisu offers benefits compared to sending all diagnostic data to some cloud server and visualising it there:

• Firstly, you don’t necessary need create any new UI since your local UI probably already has same or similar screens/features which you can utilize.
• In addition, you don’t need to send diagnostic data to the server for visualizing it, instead you have a direct access to the machine, which minimizes the latencies and enables visualizing the data in more real-time.
• WebVisu is not just a remote desktop view, it enables you to also operate the HMI remotely, you can navigate between windows and make same interactions as the local operator, there can be several remote users simultaneously and each can operate an own instance of the UI.
• WebVisu is a cost-efficient way of providing a diagnostics portal to your service organisation. There is only small one-time license fee added to the price of the Epec 6000 series unit.
