I have developed one application software using Labview 8.5 in which i am collecting data from 5 temprature controllers on serial line.

This software is done and successfully installed on customer side.

Now the customer want this software to be run on server and some fixed number of clients should access this with some login security.

Is this fascility available with National Instruments in which i can installed this standalone application in server and allow some clients to access this with

proper login?

Look in Tools-Menu under "options"...there's a categorie called "Web Server" which allows to publish VI Frontpanels in a Webbrowser and access it through network...you don't need to change anything on your software...

Hope this helps,

The attached .doc file gives you a step-by-step procedure of creating Remote Front Panels and communicating with your stand-alone application using web server.

Suppose I have Single VI open on Server sytem & there are 4 clients.

Is it possible that all 4 clients can access or gain the control of VI running on the server.But the clients should not interfere with each other. This will help me to just keep on updating VI on server & the clients will just load that VI in to their system & run their task.

Also is it compulsory to Run Labview & open VI on server machine for Web Browser to work?Because I am using dynamic caling for all sub-VIs on server.

Can you please provide steps for Labview8.6 as well. Because one of the tutorial says that we have to build & deploy the VI from a project for Web Access/Server to work.

Yes, that is possible. Multiple clients can access the VI using Web Publishing tool and control the VI operation. However, only one client has the control of the VI at one instance. The client needs to right click on the web page displaying the front panel of the running VI and ask for control and then release control after the execution to let other clients to ask for the control subsequently. The LabVIEW VI needs to be running upon the server computer since closing LabVIEW also closes the Web Publishing server and disconnects the currently connected clients.

You might want to create a stand alone executable for the same and then publish it over the internet for access by your desired clients. In that case, check this link http://digital.ni.com/public.nsf/allkb/3A0087DBE9D31F9286256B19000A2DAE?OpenDocument
