NI PCIe-6509 I/O question

[jesyf225]

I was wondering if, for the NI PCIe6509, the lines can be changed as input/output on the run, meaning, if initially I set some lines as input I can change them to be outputs while I'm running a program. I know each line can be individually set as Input or Output but I don't know if I can change them on the run. If someone could help me with this I will truly appreciate it.

I know for sure if you close the task you can create a new one, turning what was as output into an input.

That's in LabVIEW right? What if I'm using the NI Measurement Hardware Driver Development Kit (MHDDK) in Linux? Any idea? For the application I'm using I can't use LabVIEW and I need to change the lines state from inputs to outputs on-the-go

I do use LabVIEW, but that is at the driver level that I perform the switching around.  I know nothing about the MHDDK, so I will have to bow out here.
