In the example below, the FlexRIO Route Signal VI is added to the host VI to import an external trigger coming from the chassis' PFI0 into Destination0.
Figure 1. FlexRIO Route Signal (import).
Then, the signal can be received in the FPGA using an FPGA IO Node pointing to Routing\Destination0.
Figure 2. FlexRIO FPGA VI (Destination).
Likewise, Routing\Source0 can be routed to the PXI triggers, controller SMB trigger or chassis PFI to export a signal from the FPGA.

If your FlexRIO device returns an error when trying to connect directly to the controller's SMB or chassis' PFI trigger lines, refer to the related links for workarounds to achieve the same task.
