Server 2003 restriction using TCP/IP library with LabVIEW

[amittpatel@yahoo.com]

Hello

I am running LabVIEW 8.01 application on windows XP and Server 2003 machine. I want to send and receive transfer data between two machines.

So do any one deal with this kind of situation and find any problem.

Is there any problem or issues with Server 2003 which restrict connection using TCP/IP tool library that comes with LabVIEW.

Server 2003 is new and does any one know what are the restrictions or issues.

Thank you,

Amit

Check whether the Port number you write does not blocked somehow by firewall or something, otherwise (if you are sure of your code) try to do same using LV7.1 or LV8.20

Amit,

I have not dealt with data communication to/from a Server 2003 machine, but I should mention that LabVIEW is not supported for this operating system. While several customers have reported that LabVIEW will work for the most part, it is not something that National Instruments has tested or supports. For a list of supported operating systems, please take a look at the LabVIEW Release Notes.

On that note, I would be interested to see if your communication application works successfully between Windows XP machines? This would be a good test to be sure that the issue you are seeing is not the result of OS compatibility. I hope this is useful for you. Thanks,

Hello Amit!

Have you solved the problem?

I have a similar problem with TCP/IP communication on a win2003 Server machine.

The app communicates over (NI)ModbusTCP with a PLC without any problem. In the app is a 2nd TCP/IP listener for additional communication with another app. If the other app connectes to the listener (started from a WinXP machine), the ModbusTCP loop takes a break for ~5s without reporting an error...! After that everything is working fine again...

If I use for both app's WinXP machines, the loop taken no break.

Thanks for an answer!
