Combining Data out of GetPropertyValue

Good morning everybody. 

 

am using IOT Data within my experince. To do so I use Thingworx & get the data via the Get property value service within Vuforia. 

 

I now want to make a picture visible when two properties have a specific value. 

 

Property 1: Additional Sensor -> its a string which is sent. -> "Endposition Reached" 

Property2: Status of Gripper arm -> again a string -> "Active"

 

When the Properties have the above mentioned value I want to make a picture visible. 

 

Does someone have a hint for me how to do it best? Is it within bindings with filter or is it in the java script of the project?

 

Thank you!

Martin

with javascript in vuforia studio it is possible based to property change from thingworx platform.

Thank you for the reply! Do you have a code example for me? I don't know how to start that atm. 

Hi @MS_FLiX_HSD ,

I had in the past similar taks to implement but for me was the usage of  another  TWX event more convenient  in this case and I think it could be applicable also  in your case therefore I want to share this here. Lets look on the following exmple ->I have in Thingworx a Thing where I have a string property :

added e.g.  then the TWX  Event DataChange for the property (my_sensor_test1) - thing CADtestRepository  to the External Data

So I have now the event on the right side /External Data panel. I created binding to app parameters. 

  • the new value of the DataChange envent (property my_sensor_test1) I linked to parameter my_sensor_test1_newValue
  • and the old value of the DataChange event I linked to app parameter my_sensor_test1_oldValue as shown in the picture below

So also to see the value I linke the app parameters to 2 labels -  label-1 (here the new value is linked) and label-2 ( oldValued linked)

In the label I wnat to display the value (as in your example  .. active , Endstation  or something else) and want to set a color for the different  states.

After the settings mentioned above it will update only the value. To have also a different color I defined :

- Css styles in the STYLES> APPLICATION tab:

 

 

.mygreen {
  
  background-color :green; 
  color: blue;

}

.myred {
  
  background-color :red; 
  color:yellow;

}

.myblue {
  
  background-color :blue; 
  color:yellow;

}

 

 

And to set the styles depending the current value I used a $watch construct:

 

 

//================================================================
 
$scope.$watch('app.params["my_sensor_test1_newVal"]', function (newValue, oldValue, scope) {
 console.log("$watch >> newValue :: "+newValue+"  >>>oldValue :: "+oldValue);
  //handling of newVal
if(newValue!=null ) {  
  if(newValue.indexOf('active') != -1 )
  {    $scope.setWidgetProp('label-1','class','mygreen'); $scope.$applyAsync();
      
  } else   
    
 
  if(newValue.indexOf('Endstation') != -1 )
  {   $scope.setWidgetProp('label-1','class','myred'); $scope.$applyAsync();
  }  
 else 
  {   $scope.setWidgetProp('label-1','class','myblue'); $scope.$applyAsync();
  }  
    
   }//end of handling of newVal
   //handling of newVal
if(oldValue!=null ) {  
  if(oldValue.indexOf('active') != -1 )
  {    $scope.setWidgetProp('label-2','class','mygreen'); $scope.$applyAsync();
      
  } else   
    
 
  if(oldValue.indexOf('Endstation') != -1 )
  {   $scope.setWidgetProp('label-2','class','myred'); $scope.$applyAsync();
  }  
 else 
  {   $scope.setWidgetProp('label-2','class','myblue'); $scope.$applyAsync();
  }  
    
   }//end of handling of newVal
              })
 
///////////////////////////////////////////////
//======================================

 

 

So this was all, now tested the value - where I changed the property my_sensor_test1  in Thingworx UI  and checked the display in preview mode- so the color was changed/updated  according to the value setting:
