Hey together,
I've have a problem with my new cRIO system. I have the controller 9045 combined with a CanOpen modul 9881 and some AI-, AO- and DIO modules. The aim is to read/write analog data from/to sensors/actors, scale these data and write all scaled data to the CanBus using the 9881 modul. I have to run the 9881 in FPGA mode to transfer the data to the Bus. But I can't use the DAQ Assist in the FPGA Mode so I tried to create a seperate VI in RT mode and use the DAQ Assist in this VI.
My question are:
1. Did someone has done something similar?
2. How can I transfer the Data from the RT VI to thr FPGA VI?
3. Is this the right way or does someone has another way to do this?
Thanks guys

There are so many ways of establishing communication to FPGAs.
