Issue Details

When trying to use PFI lines for a hardware-timed digital task, I receive error -201062: selected lines do not support buffered operations. This error doesn't occur when using port 0. 

Error -201062 occurred at Untitiled 3
Possible reason(s):
Selected lines do not support buffered operations.

 

Solution

This error will appear if trying to use anything other than port 0 for a hardware-timed digital task.

Port 0 allows hardware timing; allowing you to use a Digital Input or Output as a Sample Clock. None of the other ports have access to this hardware-timed digital input/output functionality and therefore cannot be used in this way. 

 

Additional Information

The distinction between Port 0 lines and PFI lines will be outlined in the specifications document for your NI Device. An example for the PXIe-6375 is shown below.

 





 

You can read more on the difference between Digital I/O and PFI in chapters 6 and 8 of the X Series User Manual, respectively.
