Hi all..


I am new to cRIO and FPGA programming.

I am trying to develop a small control system using cRIO. i.e control the output using the analog and digital input signals

So, how can i send a configuration file/ set point of parameters to FPGA before starting the control system?

Hello Shiju,


Depends on how you want to set those parameters. One option that comes to my mind is opening the FPGA reference in the Real-Time process, and sending the setpoints/configuration values as front panel controls on the FPGA VI from your file.


Other option could be using Network Published Shared Variables, instead of a file, so you can set those form the host computer, too.


I recommend you read through the following resources:

  1. Data Communication Methods in LabVIEW
  2. LabVIEW for CompactRIO Developer's Guide


Moving forward, I recommend you post these types of question in the Real-Time Measurement and Control board, since that one is in English and dedicated to the Real-Time controllers and applications.


All the best,
