serial write function via GPIB interaface

[Sarwar123]

 Dear Sir,

                i want to interface DC LOAD and Multimeter with LAB View via GPIB . i want to do simple tasks. i want to write 5 different values of voltage i.e 5V, 8V, 10 V, 15V and 20V to DC Load. i want to write these values serial wise by a delay of 30 seconds within which i want to take volatge value from Multimeter. independently i can write but tell me how to write serially with time delay of 30 second. please give me feedback at your earliest. 

 Regards,

Mr. Sarwar

Dear Sarwar,

 That's a great question and I really appreciate you taking the time to write in all the details of your application. We have a very active community at NI and I believe you will get a more active response on the GPIB section of our forums. Would you mind posting the same question on that section (I've attached the link to the GPIB forum below).

So you want to do this:

1. Set DC source to 5V
2. Wait 30 seconds
3. Take measurement
4. Set DC Source to 8V
5. Wait 30 seconds
6. Take measurement
7. Set DC source to 10V
8. Wait 30 seconds
9. Take measurement
10. Set DC source to 15V
11. Want 30 seconds
12. Take measurement
13. Set DC source to 20V
14. Wait 30 seconds
15. Take measurements
16. Turn off DC source
17. Stop

RIght?

That sounds like a For Loop inside a While Loop to me...

 Post your code of what you have done so far.

Also the instruments you are using.

Also have you downloaded the LabVIEW instrument drivers for your instruments?

You might want to consider going through a few of the online tutorials http://www.ni.com/getting-started/labview-basics/
