Real-Time Measurement and Control

In LV 2010, what is the maximum number of DMA channels that are permitted between the FPGA and the RT controller?  Is it still 3?  Do different models of cRIO controllers and backplanes have a more channels?

Hi Joe,

Currently, all National Instruments compactRIO and R series FPGA platforms have 3 DMA channels to be used for DMA data transfers.  There are a few exceptions with a few of our other products noted in this KnowledgeBase article, however, and you can use more DMA channels on these specific devices.

Thank you.  I tried many different searches and could not find this knowledgebase article.

Thanks again!
