Routing PXI trigger lines using LabVIEW 6.1

[Pizzocolo]

Hello to all newsgroup,I have a problem to programmatically routing PXI trigger lines in PXI chassis.I use LabVIEW 6.1 (I know: is very old, but I need to use this version and I cannot change it....).I see in LabVIEW 6.1 the "PXI backplane" VISA class doesn't exist. So, I try to use the "PXI Instr" VISA class.  But this class is not supported by the VI "VISA Map Trigger" (which supports only VXI/GPIB-VXI Backplane in LabVIEW 6.1).Is there a way to programmatically routing PXI trigger lines with LabVIEW 6.1?I see that in LabVIEW 7.1 the way that I described here above works correctly, but, I repeat, I NEED to use LabVIEW 6.1Thank you very much and have a nice day.

Hi Gianluca,
 
Here is a <a href="http://digital.ni.com/public.nsf/allkb/CA9A49FA50393C4186256DC200774E2B?OpenDocument" target="_blank">Knowledgebase</a>&nbsp;explaining how to configure PXI trigger lines. I must confess I am not sure which version of Labview the KB is referring too, it may be a later version.&nbsp;Do you know which version of MAX/DAQmx you are using?&nbsp;
&nbsp;
I hope this resource is of some assistance to you.

Thank you for your answer, but I guess that cannot solve my problem.My need is to PROGRAMMATICALLY routing PXI trigger lines using LabVIEW 6.1 and not to fix them using the MAX.I need to do something like this: <a href="http://digital.ni.com/public.nsf/allkb/A4DA71CA2F68306686256ED8005515ED?OpenDocument" target="_blank">http://digital.ni.com/public.nsf/allkb/A4DA71CA2F68306686256ED8005515ED?OpenDocument</a> But these operation doesn't work in LabVIEW 6.1.Have a nice day.

Hi Gianluca,
Which version of NI-Traditional DAQ and of NI-VISA drivers are you using?
I think your problem could be caused by the fact that the part of the driver used to perform the routing is not compatible with LabVIEW 6.1 as LabVIEW 6.1 only works in traditional DAQ and the routing software uses DAQmx.
My suggestion is to try to upgrade your NI-VISA (you can download the correct version from this <a href="http://joule.ni.com/nidu/cds/fn/p/q/NI-VISA/sb/navsRel/lang/it" target="_blank">link</a>).
Also, refer to examples in LabVIEW Find Examples.
I hope this upgrade&nbsp;will solve your problem!
Bye!

Hi Licia,
I installed both the NI-DAQmx v8.6.0f5 and the Traditional NI-DAQ v7.3.0f1.
I suppose these versions are correct, because if I use LabVIEW 7.1 in the same PC, I can route the PXI resource.
I think is not a driver problem....&nbsp;&nbsp;&nbsp;Could&nbsp;be a LabVIEW problem, which using&nbsp;v6.1 doesn't allow this kind of function?
Thank you.

Yes, your drivers versions are ok, but remind that LabVIEW 6.1 is only supported by Traditional DAQ, so be certain you are using these drivers.
In the KB you were referring to, it's indicated that VISA drivers version must be 3.1 or later in order to be able to programmatically route the PXI trigger lines: have you checked this? Otherwise, update VISA drivers.
If you are not still able to route the triggers in that way, maybe the routing is only supported by DAQmx (this <a href="http://digital.ni.com/public.nsf/allkb/BD37A128B1DF27F3862570FC0072359D?OpenDocument" target="_blank">KB</a>&nbsp;seems to indicate so), so you should use LabVIEW 7.1: why&nbsp;is it&nbsp;a problem for you?

Hi Licia,
of course, I already checked the VISA version: it is 4.2.
Probably the problem is LabVIEW 6.1 that not support this operation.
For me it's very difficult to use LabVIEW 7, because the application is very very very big and it was developed on LabVIEW 6.1: change it meaning to work for two month for the porting....
In any case many thanks for the answer.&nbsp;Gianluca&nbsp;&nbsp;
