Get "Session Invalid" error after running a vi in for loop.

[Shridhar]

Hello,

I am running a vi in for loop. This vi controls Tek AWG520. After few iteration of this loop I get "Invalid session handle" error.

Please let me know the possible cause & any solution for the same.

Thanks & Regards,

Shridhar.

please show your loop, or better post the program in its simplest form.

What are you trying to accomplish with running your VI in a loop? Are you including the Initialize and Close VIs in a loop? Are you using an IVI driver? Send us your VI and a screenshot of the error.
