Error -201062 When Outputting Hardware-Timed Task on My NI Digital Device

Issue Details

• I need to run a hardware-timed task on my NI Digital Device; however, when I configure my task to include certain ports/lines. I receive Error -201062, pictured below.
• 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 Untitled 3
Possible reason(s):
Selected lines do not support buffered operations.
 

Solution

Error -201062 occurs when the selected physical channel does not support hardware-timed digital tasks. On X Series modules, only Port 0 supports hardware timing for digital input and output operations. If you're using a device from a different product family, consult its User Manual to verify whether it supports hardware-timed digital functionality. 

Additional Information

With X Series devices, only Port 0 can be used with a sample clock, enabling hardware-timed digital I/O. Other ports lack access to this timing circuitry and therefore cannot be used for hardware-timed tasks. Attempting to use any port other than Port 0 for such tasks will trigger the error.

The distinction between Port 0 lines and PFI lines will be outlined in the specifications document for your NI Device. An example of 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.
