Polling method isn't retrieving data

[George1020]

Hi, 

I have created a vi project that I am trying to link to my data dashboard app on my ipad. I've linked my VI's correctly through a web method and I've polled my indicators and called my controls. I see the different controls and indicators and I am able to choose them correctly. However, the data isn't showing and an error comes up saying that the data cannot be retrieved. Does anyone know why this might be?

Hi George,

What data types are you using for the controls and indicators? Are you able to interact with the web method from a browser on the development computer?

If so, can you post the specific error/warning you are seeing?

Thanks!

Hi Zach,

Can you explain to me how to test the data from a browser?

The controls I have are: one drop down ring string menu, 2 sliders and 2 knobs.

The indicators I have are 4 knob meters, 1 thermometer, 2 gauges, and 2 numeric indicators. I've attached the project for more clarification!

You can find more info on accessing web services here:

Data Dashboard specifically needs XML output format for accessing terminals:

You should be able to type in the web service address [IP address]:[port]/[Web Service Name] and see the XML version of the web service.
