Multiple counter input using NI 6602

[S._LaCoursiere]

I am using NI-DAQmx to write a VI  that will read 10 pwm measurements using 10 counters on 2 NI 6602 PCI interfaces.  It is my understanding that I must create a task for each respective counter.  I have attempted to implement a for loop to accomplish this, as shown in attached VI draft.  As it stands the VI will not write any data to file.  I suspect there are multiple errors in the VI.  I would ask if anyone could take a look at the attached VI and perhaps provide some insight?

I should note that I am using LabVIEW 8.0

Hi Saul,

It looks like you had a subVI "Create Header" which needs to be included to run, so I deleted all of the report related code.  The Counter portion ran fine.  If you can't get the report generation portion to work, you may want to simplify your code (for example start with a single counter task) and build up from there.

Please repost if you have further questions.

Thanks,

Luke,

Thanks for the reply.  It isn't quite clear to me what you deleted when you say "report related code."  Could you attach the VI with the deleted code? 

Thanks,

Saul
