A’ cruthachadh soitheach Node-RED

Tha an stiùireadh seo a’ còmhdach stàladh soitheach Node-RED air Pixsys. 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.

Log a-steach

Access the device in configuration mode by holding down the STOP button that appears at startup.
Faigh cothrom air consol rèiteachaidh le bhith a’ cur a-steach na teisteanasan a leanas:

Ainm-cleachdaidh: cleachdaiche
Facal-faire: 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/ agus a’ cleachdadh nan teisteanasan gu h-àrd.

A’ cruthachadh am pasgan airson Node-RED

Feumaidh an soitheach a thèid a ghnìomhachadh àite airson dàta luchd-cleachdaidh a stòradh.
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/user
• From the Menu “New” select the option “Directory…”.
• Create the folder node-red, enabling all “R/W/X” permits:

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

Download of the container

Faigh cothrom air “Podman containers” air a’ bhàr-clàr:

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

Select the search area “docker.io“Type “node-red” in “Lorg airson"

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

Then press “Download” and the download of the image will start.

This is a several hundred Mb file; depending on the internet connection, it may take several minutes.

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

Fill in the “Name” field with a name of your choice, replacing the automatically generated random one.

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

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:

Aig seo stage, press “Create and run” and wait for the creation of the container.

Install “node-red-dashboard”, opening the Menu Manage palette:

Lorg airson node-red-dashboard within the 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:

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

Cho luath ‘s a thèid an còd a thoirt a-steach, bheir seo seachad pròiseact mar an tè a leanas:

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.

Upon reboot, the device will show the full-screen Node-RED Dashboard.
