How to program multiple peer-to-peer streams between multiple PXIe devices?

[Trekkie123]

I read in NIs Peer-to-Peer Streaming documentation that it is possible to create multiple Peer-to-Peer streams between multiple devices. For my project, I want have a PXIe-5122 Oscilloscope act as a writer, the PXIe-7846R act as a reader (from the 5122) and as a writer, and a PXIe-7915 act as a reader (from the 7846R). To implement this multi-stream design, will I need two Open FPGA VI Reference functions for the PXIe-7846R (one for reading, one for writing) or can I branch off of the same reference function into the FIFO Reader Invoke Method and FIFO Writer Invoke Method? I have attached a photo of my host computer VI at the moment with two Open FPGA VI Reference functions for the PXIe-7846R, is this right?

Hi Trekkie123,

You may use the same FPGA reference wire to set up the streams as the FPGA VI have both writer and reader peer-to-peer FIFOS set up.
