Application for the logic.hub:



Sawdust
automatic dust extraction

Automated dust extraction system

With this application, we show you how you can automatically use your extraction device for the dust generated during sawing with an electric saw: Extraction starts automatically when the saw is switched on and continues for a certain time after the sawing process has finished. This means you can concentrate fully on sawing and don’t have to think about switching the machine on and off manually. The configurable run-on time ensures that the extraction runtime corresponds to the amount of dust produced and other specific requirements of your work process. Find out below how you can easily realize automation using drag’n’drop.

Automate extraction dashboard setup: What is explained



1. Setting up the flow

  • Click on the images to enlarge!

    Save terminals
    • Open the web interface of your logic.hub and click on Terminal inventory.
    • Click on ADD W&T TERMINAL, or on the Plus sign to add devices from other manufacturers.
  • Set up terminals
    • Then click on ADD SELECTED TERMINALS.
  • Set up terminals
    • Click on the Pencil icon pencil.
  • Set up terminals
    • Activate logging at the terminal to which you want to connect the suction unit later by ticking the box next to Activate logging, and then click on OK.
  • Save terminals
    • Once all terminals have been added, you only need to save.
  • Save terminals
    • Adding a Web-IO Digital.
    • Make sure that MQTT is activated and that the IP address of the broker (logic.hub) matches.
    • Publish and Subscribe must also be activated, as shown in the image.
  • In the web interface of the logic.hub click on Logic Editor.
  • You are now in the Logic Editor. Create a new page by clicking on CREATE NEW PAGE. If you have already set up pages, you need to click on the Plus to create a new page.

  • Create comparison
    • Add the node TP (Pulse Timer).
    • The TP node (Pulse Timer) switches to "True" as soon as the input value is "1". It switches to "False" (input value "0") as soon as the time at input "PT" has elapsed and input "Q" is "False".
  • Create comparison
    • Set the CONST node to Analog and the analog value to the desired remaining on-time: in our case to 5000ms.
    • The remaining output can be assigned an analog output to indicate the remaining time for which the extraction remains on.
  • Create comparison
    • Here too, you can name and color-code the nodes as you wish.

2. Visualization

  • Set up terminals
    • Click on Dashboard on the web interface of the logic.hub.
    • Create a new dashboard by clicking on ADD DASHBOARD.
  • Set up terminals
    • Use the LED label to indicate whether the saw is active or not.
  • Set up terminals
    • As a destination for the LED label use the output of the Web-IO to which the extraction unit is connected and optionally the input to which the saw is connected.
  • Set up terminals
    • Use a large ticker label to have the time indicated.
  • Save terminals
    • Optionally you can add the diagram label and also use the extraction as the source. You can now display the extraction curves over a specific period of time.
  • Save terminals
    • In addition you can add a Switch and a Slider label in order to manually control extraction remotely.
  • Create comparison
    • You can label the tiles as desired.
  • Create comparison
    • For the diagram, in our example we use a day and the line type Step
  • Create comparison
    • Save, and the extraction control with dashboard overview is complete.
