how to use virtual cards

[satvrn5]

Hi!

I work on a LabVIEW code which uses 5 cards NI (6503,6023,6023,6503,6704). I want to simulate these cards. So I created Ni daqmx simulated cards. when I launch  the labview program, I obtain the error -10401 when I try to use DIOconfig.vi. For information, I use the traditionnal daq driver 7.4.2.

 Is it possible to call virtual peripherals ?

Thanks.

Traditional DAQ does not support simulation. You created them with DAQmx and that is what you must use.

Thanks for your reply! I have another question. I work with daq-mx. Is it possible to write digital ouptuts and then read them just using Labview?

 I work with LabVIEW 8.2. First I create a channel and start a task. Then I run a loop in which I write and read continuously the same port. But I never see this changing...
