Why Can't I Tristate My NI 6509 Digital Lines?

Hardware: Digital I/O (DIO)>>Static>>PCI-6509, Digital I/O (DIO)>>Static>>PXI-6509

Problem:
Why do I get error -200077 when I programmatically set my NI 6509 ports to tristate?



Solution:
DAQmx 8.6 and Before
The NI 6509 is programmed port-by-port and the DAQmx Channel property DO.Tristate is configured line-by-line, which makes the combination incompatible. A subVI has been created as a substitute for the property. Replace the DO.Tristate property with the subVI attached below.

DAQmx 8.7 and Beyond
The NI 6509 will support line-by-line tristating in DAQmx 8.7.
