建立 Node-RED 容器

本指南涵蓋了在 Pixsys 上安裝 Node-RED 容器 WebPanel “WP” and TouchController “TC” series.
Displaying the Node-RED dashboard on the screen is possible only on WP – WebPanel devices and on TC – TouchController panels with the “WebVisu” license only. On TouchController – TC panels with a “TargetVisu” or “TargetVisu + WebVisu” license, it is not possible to display the Node-RED dashboard.

登入

Access the device in configuration mode by holding down the STOP button that appears at startup.
輸入下列憑證存取設定控制台:

使用者名稱: 使用者
密碼: 123456

If the device IP is known, it is also possible, and recommended, to access the configuration console from a browser on the user’s PC by accessing the address: https://device-IP-.9443/ 並使用上述憑證。

為 Node-RED 建立資料夾

即將啟動的容器需要一個空間來儲存使用者資料。
For this purpose, in the devices, there is a folder /data/user.
Using WinScp or another sFTP access software, create a folder node-red within the path /data/user, following the steps below:

  • Open WinSCP, connect to the device using the IP and credentials already used to access the configuration console, and choose /data/userPixsys Web Panel Touch Controller Software - Creating the folder for Node-RED
  • From the Menu “New” select the option “Directory…”.Pixsys Web Panel Touch Controller Software - Directory
  • Create the folder node-red, enabling all “R/W/X” permits:Pixsys Web Panel Touch Controller Software - Create the folder node-red enabling

The same process is also possible by SSH access and using the following prompts:
mkdir -p /data/user/node-red
chmod a+rwx /data/user/node-red

Pixsys Web Panel Touch Controller Software - Same process is possible also by SSH access

Download of the container

在功能表列上存取“Podman 容器”:Pixsys Web Panel Touch Controller Software - Download of container

Select the option“Download new image” in the menu to the right with the three-dot icon

Pixsys Web Panel Touch Controller Software - Download new imageSelect the search area “docker.io“Pixsys Web Panel Touch Controller Software - Select the search area在“中輸入“node-red”搜尋

Pixsys Web Panel Touch Controller Software - “node-red

Select official image “docker.io/nodered/node-red”:

容器創建

In the “Containers” Tab, press the “Create container” button. A menu will open to configure the container you want to create.

Tab Details:
From the “Image” box, choose the downloaded image as described in the previous chapter:

Pixsys Web Panel Touch Controller Software - Tab Details

Configure “Memory limit” to 128 or 256 MB.
“Restart Policy” set to “Always” sets the container to start automatically and be restarted even in the event of a user-commanded shutdown.

Tab Integration:
Configure port mapping to expose port 1880 in both TCP and UDP, and map the Container Path /data, visible from node-red, in Host Path /data/user/node-red

Tab Health check:
This Tab defines the control checks on the correct operation of the container and how it will behave in case of an error.
The image below shows the default parameters:

測試容器

When the container creation procedure is finished, the “Containers” list will display the new running container (State: Running):

Pixsys Web Panel Touch Controller Software - Testing the container

Open a browser on PC and go to the page: http://device-IP.1880

建立儀表板

儀表板允許 Node-RED 呈現/發布動態 web 頁。
Install “node-red-dashboard”, opening the Menu Manage palette:

Pixsys Web Panel Touch Controller Software - Creating a dashboard

搜尋 node-red-dashboard within the tab Install

Pixsys Web Panel Touch Controller Software - <span>Search for</span> node-red-dashboard within tab Install

Wait for the installation to be completed, and then log in to the console and import the Flow entered at the end of the guide from the menu Import:

Pixsys Web Panel Touch Controller Software - IMport

**這是前ample code with no real purpose.
NB for the use of Node-RED and the Dashboard, please refer to the documentation available online.

Opening page http://device-IP.1880/ui, the result will look like the following:

Pixsys Web Panel Touch Controller Software - result will look like the following

配置面板以顯示儀表板

At this point, for panels that allow it, access the menu WP Settings, then Main application settings, and enter URL http://localhost.1880/ui
Use the term localhost or IP 127.0.0.1 to make the browser access the device itself, regardless of its actual IP.

Pixsys Web Panel Touch Controller Software - Configuring the panelUpon reboot, the device will show the full-screen Node-RED Dashboard.
