Hello,
I am using a PCI-6025E DAQ card in a PC running WinNT, and am trying to interface to it with Labview 6.0.2.
More specifically I try to use portA and portB at the same time (two of the three digital I/O ports that the card has.)
I am trying to write and hold a digital 8-bit pattern on portA, then write another pattern on portB.For this purpose I use the "Write to Digital Port.vi" twice, within another VI. I slightly modified it with "error in" and "error out" terminals to ensure they operate in the correct sequence, but I doubt this is causing my problem.
My problem is that after I write (successfully) to portA, portA is grounded (reset?) before proceeding to write to portC (again su
ccessfully.)
I opened up the VI and cannot seem to find a reset command anywhere in it -though I don't understand everything in there, so I could be missing it.
How do I get to use two copies of this VI as sub-VIs without having them interfere with each other? I need to hold their outputs to the correct value simultaneously while a third VI executes (it involves the counter.)
Thank you,
-Alexander
