Change IP-number and Subnet-mask with LabView?

[zav]

To upgrade the software on a CRio-System, the user needs to change some settings in the TCP/IP-configuration.

To simplify this task I think on a possiblity to do (and at the end redo) the changes in the TCP/IP-Configuration of the Windows PC.

What I need is:
- Change the IP-Adress (from "Obtain IP adress automatic" to IP xyz...)
- Change subnet-mask
- Redo this settings by saving an existing config or set to "Obtain IP adress automatic"

Who knows if and how it's possible to do that in LabVIEW?
Perhaps I have to call a script  /.bat-file?

LabVIEW 6,7 and 8 available 🙂

Try netsh and a bat file. Rename the first file to .bat.

hi there

you can use the netsh environment on the command line. for example

netsh set address name="LAN-Verbindung" source=static addr=10.0.5.99 mask=255.255.255.0 gateway=10.0.5.1

see windows help for more information.

Hi, its a really interesting stuff to read. Did anyone try doing it ?

One thing that I wanted to know was: How long does it take to do this ? Since Im using a time critical application, can this entire operation happen in 100 milli seconds ?

Will be glad to hear from you.

I have used this for a program that needs to have a host IP address for High sped cameras. I have it change the IP address to the required address and change it back when I am done. Here is a very simple Labview version of this code with out the switch back.

If you want to know how long it takes, run it yourself. You certainly do not need LabVIEW to run a DOS command. If I recall, it's going to be pretty dependent on your OS and pc. I also don't recall ever coming close to 100 msec but it's been a few years since I've done it and the timing was not at all critical for me.

You can set the system exec not to "wiat until complete". This will return an error code and you can react to that.

[Sreedhar_T]

Hi,

Could you please explain me: "set the system exec not to "wiat until complete"."

Is it done in LabVIEW ? if yes, how and where.

I tried running this batch file on my PXI-8109, but it is taking some 3-4 sec. Any help to improve this will be highly appreciated. I need to complete the entire operation with-in 100ms.

In the code that I sent the system exec is the VI that looks like this.

The boolean that is on top is the wait until complete boolean. Set this to true and look for the return code.

[Sreedhar_T]

Sorry for the trouble. After I checked your code, I was pretty clear what you meant.

But, I'm still facing the timing issue, it is taking almost 2-3 seconds for its completion. By making the "Wait till Completion" as false, I am only releasing the CPU for my internal operations, but I cannot use the new IP address untill it is actually changed.

Thinking to implement virtual ip concept, will keep posting

thanks.
