I am trying to run multiple relays from two NI 9481 cards in a cDAQ 9188 for a multiple channel temperature control application. Attached is the relevent part of the code that worked before the second NI 9481 card was added to the system and still works fine when addressing a single card. However, when adding the physical channels from multiple cards at the same time, the code gets stuck (infinte loop, nonrepsponive labview) in the DAQmx Create Channel block.
I also tried to create the channels for each NI 9481 card seperatly and then pass the tasks to the DAQmx Start Task block....same thing happened.
I also tried to use two separate sequences of code is parallel for each NI 9481 card identical to that shown here but (of course) it just generated an 50103 error at the DAQmx Start Task block. I went through the cases on the 50103 error page at http://digital.ni.com/public.nsf/allkb/485201B647950BF886257537006CEB89 without resolving the problem. So...is it possible to simultaneously address two NI 9481 cards in a single cDAQ 9188? Thank you. -Max
