Re: Problem with simultaneous DIO with PCI-6024E

You are correct in assuming that the port is reconfigured each time in
a loop iteration when using high level VI's.  One solution would be to
use one port (bits 0 to 7, or Port 0) to set your output bit high.
Use a different port (Port 1 or 2) to read your required inputs.  If
wired correctly, port 0 will always be an output and will keep your
bit high while reading port 1 or 2.  Using high level VI's, you will
not be able to write one bit high and expect it to stay high when
reading other bits on the same port.

Problem with simultaneous DIO with PCI-6024E

[DavidT]

Hello All,

I am having a problem with performing simultanous DIO tasks with my
6024 card. I need to write to a DIO line a high signal, whilst at the
same time, reading from 2 DIO lines. When I perform these two tasks on
the same VI, the write DIO will change from the required high state to
a low state. (I need this to stay high as it enables a drive).
Im using high level VI's (Read and Write to digital line VI's) since
im a relatively new user and I think this might be the problem, as the
port is being reconfigured each time I do an loop iteration.
Any suggestions on what I can do to overcome this, or any examples on
how to use high level vi's?

thanks all in advance,
David
