reset output terminal daqmx for counter

[_Faust]

Hello everybody,

I am really stuck with the USB 6343 currently: I am using the 4 counters on this USB device to generate output pulses on PFI0 to 10.

It works fine, but when I run the example from the figure below for output terinal PFI0 (I have attached LEDS) it runs fine.

Now if I select PFI1 for the second time I run this VI, then PFI0 ALSO fires simultaneously.

So for some reason this mapping is not cleared when the task is terminated. Only thing that works is disconnecting the USB plug and plugging in again.

Any suggestions?

Hi Faust

I think you will find the following article usable:

Please let me know if this solves your problem:

Thank you Anders. I will reply with my finding

Well, this works! Do you also know how I route multiple output ports to a single counter (in one instance)?

When I use the property node twice for output terminal in the same task, it returns an error.

I actually used my 'problem' sometimes to my benefit when I want 2 terminals to 1 counter, by running the VI twice.

Thanks again for the help

Thank you for the suggestion.

I can route multiple output terminals for CNTR 0 and 1, but it returns an error for cntr 2 and 3 (always).

Hi Fous,

Which error do you get every time? Could you make a screenshot of it and reply to this ?

Thanks,

Hossein

Yes, I can see attached!

I put a case around the  ''DAQMX Connect Terminals" subvi. I can use this for cntr 0 and cntr 1, and it returns an error for cntrs 2 and 3.

When I select only 1 outut terminal for cntr 2 and 3 it works fine (so setting case to F)
