I've got a new PCI 6509 Digital-IO-Card. It works quite fine, if I'm using one Port as input and another one as output. But if I'm going to try to use one Port as In- and Output there are some problems.
I planned to use the first 4 lines of port0 as input and the last 4 as output.
I've defined two DAQmx-Tasks (Line-Input and Line-Output). After that I had tested both tasks separately and there were no problems, but when I tried to use them both in Labview the same time it didn't work.
First the VI is setting the some output-lines. (works)
Then some lines are read out (works) , but in the same step all output-lines are set back to LOW. (why?)
Isn't possible to use some lines of ONE port as Input and some others of the same port as Output or is there any other reason?
