Remote panel in a web browser: nothing on the screen

[loupiac45]

Hello everybody,

To get my VI application in a web browser, I followed a tutorial:

http://www.ni.com/tutorial/4791/en/

Indeed, I would like to make a remote controlled experiment by using a web browser.

However, even if I took care to follow exactly what was said in the tutorial, I got a white screen instead of the VI view.

I put the plugin needed and tried on several browsers (Internet explorer, Chrome and Firefox but still the same problem)

Do you have a solution?

Tell me if there is any other possibility to make a remote controlled experiment.

Thanks in advance.

I also had this page.

I built my application and tried to do the same thing but still the same problem.

Am I the only one to have this?

Do you think it is due to the browser?

Thanks in advance.

If it is showing the loading screen then that probably means that your browser and the NI plugin are working fine.

If it isn't downloading the panel - some things it might be are:

- Wrong IP address/port of cRIO in the html code

- A network configuration issue (e.g. firewall blocking communication, no route to the IP address)

- Incorrect VI Server settings (blocking access - make sure the Project/Target allows VI Server connections

- Might be that you need to install some additional NI components on the cRIO to allow remtoe front panel connections

To simplify things, I would perhaps create a simple VI on your computer (rather than the cRIO) and try the remote publishing tool on that - that will help to rule out IP/network configuration issues.

And if you are looking for another solution for accessing/contrlling a LabVIEW application through a web-browser - you might want to look at my WebSockets library (and links in my signature) - https://decibel.ni.com/content/docs/DOC-41778

Thank you for your reply.

You are right, the problem come from the network because when I tried with another computer it worked.

I saw your solution with Websocket library. It's very interesting but too much complicated for me...

Thanks again!
