My system has a PCI4661 DAQ and an PCI1588 sync'd to PTP. I have CVI 2015 anD NI Sync 16. I also have other network devices set to PTP.
My appliation requires all devices 4461 AO/AI and network devices to trigger and I am sucessfully using the 1588 to trigger my 4461 future timed event. The trigger is generated over RTSI.
I also need to respond to an external trigger edge and I am trying to connect an application callback to one of the PFI terminals (either 4461 or 1588). From the callback I can get the timestamp of the edge and then create a future event to start all devices triggering.
I have done quite a bit of reading around can not find a way to use a PFI to generate a software event. I understand that PFI does not provide fulls buffered operation but I simply need one way or another to get a software event.
Does anybody have any ideas to how to get an event ?
Thank you in advance, the support from this forum is invaluable.
