I am using a cRIO-9053 with all c-series modules in scan mode and need a simple software-timed digital output to use for an LED status indicator. Since none of the modules contain a digital output, I am hoping to use the PFI 0 terminal on the cRIO chassis for this function.
I've made numerous attempts using DAQ-MX with no luck. Is there any way to simply write a Boolean value to the cRIO PFI 0 terminal from the LabVIEW real-time programming side?
Solved! Go to Solution.
I know the PFI terminal can be routed to the FPGA, so that can be a solution if you're using this hardware resource in the cRIO: Using PFI0 in the FPGA of the CompactRIO With DAQmx
Moreover, the PFI goes through the DAQmx ASIC, so I presume a counter should be able to output a signal through there: How to Output a Digital Signal from a cDAQ PFI Chassis Terminal
(Disclaimer: I have never tried this, and cannot ensure it will work, but it's worth a try).
Thank you for your reply. We aren't using the FPGA as a resource in this application, but I was able to get it working using the example shown in How to Output a Digital Signal from a cDAQ PFI Chassis Terminal.
Thanks - much appreciated!
