labview on a DNS

[NathanK]

In recent versions of LabVIEW (I believe it was put in in 8.2 or 8.5) you can simply mark your VI as reentrant and each remote panel client will get their own instance that they can control.

You would still need a license to be able to have more than 5 clients connected at a time. If you are going to make this available on the the internet you might need to do some load testing. If the VI's are very complicated having a lot of them running on the server at the same time might take some power.

If you read Nathans answer again, it seems that if you make the Vi reentrant, each client will get a new instance that he can control independently.

I have not tried that.

  so if i buy the remote panels does that mean only 5 people can go on the website? or does that mean i can only have 5 VI Panels on the website? what if i have 60 people using this application over the internet?

Did you read the information on the remote panels page? Each license is for a single connection.  You get five licenses with LabVIEW Professional (5 connections allowed) and 1 license with LabVIEW Full (1 connection allowed). Each client requires that the LabVIEW runtime be installed, though there is no charge for this.

For large numbers of connections, you might want to look at the web services option in 8.6. You would have to do some programming in another language.
