Sharing live data over the internet

[ishank]

Hi,

I want to share live data of my experiment over the internet. I am using LabVIEW 8.0.1. I tried the Web Publishing Tool, which helps me to control my VI over LAN, but when I try to open the web page from outside my office internet network, the message "connection timed out" appears. The same goes for TCP/IP, when I try to connect from PC running a different internet network, ERROR 56 occurs. Ditto for datasocket server. 

Please help somebody.

Hi ishank,

do you mean LabVIEW "error 56"? I thought you want to connect through a webbrowser to your VI. Are you behind a router? If yes, then you have to forward port to your pc, where the webapp is running.

@muks: I tried your solution but it is showing the same error. Can you suggest something else. I am running VIs from labview examples, "Data Server" on 1 PC and "Data Client" on the other, and all I get is "Error 56:Connection has exceeded user specified time limit".

@Mike: Yes, I was talking about labview error 56. I didn't understand your solution, can you please elaborate.

Thanks for replying.

Hi ishank,

i'm not sure if i understand what you try. I thought you would see your vi over the webbrowser, but if this is the case, then i don't understand the error message. Can you show your vi and explain how you try to call it from outside? How do you call it from inside your network?

Hey Mike,

First,  I used web publishing tool to embedd a VI in browser, then I tried communicating through TCP/IP by running Data Server.vi on 1 PC and Data Client.vi on the other. After that I tried communicating through datasocket server by running DSwriter.vi on 1 PC and DSreader.vi on the other. When I do this at my workplace with two PCs running labview, it works fine, but when I tried with two PCs having different internet connections, opening a web browser showed "Connection timed out", running the other VIs showed "Error 56". I've even tried disabling the firewall and let one PC work as a server, but it didn't help.

Hi ishank,

now i understand that you tried two different ways.

To which computer IP do you try to connect if you are outside your network? You should use the IP from the PC/Router which is connected to the internet and forward one port to your pc where one of your applications is running.
