Error -200022 from PXie 6556 cards

I am running into trouble when running my application to synchronize 3 PXIe 6556 card. How could I fix it?

 

Error:

ni HSDIO Initiate.vi<ERR> Driver Status (HEX 0xBFFA4014)

Resource requested by this session has already been reserved by a different session.

Property: RefClk.Source

Reserved Value: None

Requested Value: PXI Clock Line

Status: -200022

 

Thanks for your help.

Yes, that is the typical expected behaviour if you do the initializations repedetly in the loop. Move the initialization vi's outside of the loop.

Hi Roger,

 

If I move them outside of the loop, it have a new error

 

ni HSDIO Wait Until Done.vi<ERR> Driver Status: (Hex 0xBFFA4008) Maximum time exceeded before the operation completed.

 

How could I fix it?

 

Thanks and Best regards,

AnDong

Hi,

 

Does your signal generation operation take longer time than what you have specified in the input terminal:

Try changing the timeout value and run the code with "Highlight Execution", see where the error occurs.
