Remote Front Panel in Web Browser

Hi Forum.
 
I am having great  difficulty in developing a web published application.  
 
Currently I have an example VI from NI Examples >> Chart.vi.
 
I enter the address into Internet Explorer 8 and I get "Internet Explorer cannot display the webpage"
 
I have ensured the following:
 
I have installed LabVIEW run time engine 8.6.1 as I am developing LabVIEW 8.6.1.
I have ensured the Web Server is running with all the * in the right places.
I have tried changing the port.
I have ensured the plug-in is saved within IE.
Windows Fire wall is off. I have another protection software which is on - but when the fire wall is switched off - I still have the same error.
The VI is loaded in memory and running.
I have tried both snap and monitor applications in the wizard.
 
I am using LabVIEW Student Edition - does this make a difference? I think not, as I have seen it work on this machine before.. just can't seem to get it work anymore.
 
Your help would be very grateful as I am going around in circles.

James

Hey James,

 

I hope school is going well! In regard to the problem, I would double check the following: 

 

- "Remote front panels" is checked in the web server configuration

- Nothing else is running on the same port... although you said you tried changing the port. When you did this, did you make sure to specify it in the URL, as in http://localhost:85/panel.html

- Have you tried another browser?

- Check the log file in labview\resource\webserver\logs and see if there's anything useful...

 

Cheers,

Hi Misha,

 

I am fine thanks - hope you are too.SOrry for the delay.

 

I am still having issues.

 

To summarise:

 

The server with LabVIEW 2009 is all installed, published and settings are correct - I can open IE 7 and see the image update every X seconds.

 

The client machine has LabVIEW 2009 run time engine. I have checked the the IE pluggin is within the IE folder. (Windows XP). IE shows Internet Explorer cannot display the webpage.

 

I have tried different ports - with the same result.

 

I have tried different types of publishing.

 

I took a look in the log file - and saw norequests from my client machine as expected? - as its not working.

  The access file did have the connections from the local web browser - with no port errors.

 

Clearly, some sort of network issue. Both machines can ping one another. What other settings would prevent this?

 

Your prompt response would be great!

 

James

Hi ,

 

Thanks for your reply. As far as I know the firewall is off on both PCs - something to check. What type of setting would block this traffic?

 

When you say message what do you mean? When I ran the VI is just runs - no errors are display...

 

Thanks,

 

James

James,

 

Just wanted to clarify a few items to see if I might be able to assist.

I'm assuming the following:

1) You are running the VI on a machine with LV 8.6 (student edition)

2) This is running as a LabVIEW VI, not a built application (exe)

3) You want to access this VI using Web Server from a PC with LV 2009 RTE

4) When you configure the Web Publishing Tool you are saving the file to:

      C:\Program Files\National Instruments\LabVIEW 8.6\www\your.html

 

From the client machine you enter the address into IE8 as

  http://(Server PC IP)/your.html 

 

The LV 2009 RTE on the client will expect to find this file at:

     C:\Program Files\National Instruments\LabVIEW 2009\www\your.html

Maybe try creating this directory and placing a copy of your.html file there.

 

I hope my understanding of your problem was not completely wrong.

 

Regards,

 

James
