sequencer clearing with DLL references

[AEC ENGINEER]

HI,

I have two VI each one of them communicate with same library (.net).

when I run each of them individual it works fine. but when i tried to run it using Test stand, 1st step (1st VI) is working but it does not pass in the second step (2nd VI).

I think the problem comes from the library, where when i tried to run 4UUTs using batch technique, only one unit is passing the test and the remainng uuts are failing. 

how i can make sure the library is totally closed from the VI and/or Teststand as well.

note: the function of the vi is to communicate to the UUT using com port (4 seperate ports for each UUTs).

thanks a lot

AEC ENGINEER,

There could be a number of things going on. It could be something as simple as simply not changing the com port correctly, or we may not be closing out the device reference, or a number of other things. Could you post a simple example or some screenshots of the code so we can try to see if there is anything that looks out of place? 

Regards,
