Is device resseting neccessary to use DAQmx after trad daq?

[jolly jumper]

Hello.

I have a driver problem. First I use trad daq to generate a digital puse train and read/write two lines. This works without a problem and I close the tasks before the vi stops, but after this I try to use DAQmx (in another subvi, but not simultaneously). In the main vi I have a case strucute and depending on a button I launch the matching subvi and get the error bellow.

Do I have to reset my device (how would I do this)? It could also be possible that I didn't clean up the tasks rightly.

Please help,

kind regards peter

Hi Peter,

Yes you have to reset your device, but this could be done very easy programmatically with the DAQmx Reset Device.vi,

located under Measurement I/O > NI DAQmx > Dev Config !

hello christian,

thank you for your reply, but I'm sorry, because that doesn't work 😕

First I started the subvi Initialisation.vi (that uses trad daq) ... then I got back to the main vi. After this I tried to restart the device the way you told me and start Control.vi, but I got the following error (bellow)

Hey christian,

now I've already fixed the bug!

I have to use the "traditional" <reset device.vi> and it works....

thank you very much,

kind regards peter

Sorry Peter, didn't know that there is a difference between them, because i only have DAQmx installed
