8. Adding Data to Template Node

Next, we will populate the template node with data from two different motors. We will insert an inject node and a function node and connect them to each other.

Double-click on the function node and copy the following code

min = Math.round(Math.random()*1000);
max = Math.round((Math.random()*10000)+1000);

msg.payload = {
  factory: {
    machine00: {
      min: min,
      max: max,
      failProb: 20,
      name: "Motor 1"
    },
    machine01: {
      min: min*5,
      max: max*2,
      failProb: 10,
      name: "Motor 2"
    }
  }
}

return msg;

and change the name to Generate Data.

Click Done once the function is complete.

We will use the inject node to trigger this function every 3 seconds. To do this, double-click on each inject node and change the following parameters.

Click Done after parameters are set.

Drag and drop a comment node and name it Water Filtration. Click Deploy and go to your dashboard page to see your progress.
