Hi,
I have a Compact RIO (controller 9024, Chassis 9118, modules 9514 (control) and 9237 (load cell acquisition). I want to control it in force feedback i.e. the measurement of the load cell used as a feedback by the PID control.
I would like to base my programm on the example Servo Interface (9514).lvprj which use the softmotion toolbox. I'm a beginner in Labview, control and acquisition so I'm not sure about how to do it.
Here is the step that I think :
1. In the FPGA VI, replace the encoder 0 (local variable) in the PID part of it (see attached file name PID control) by the 9237 I/O.
For the load cell part, I inspire my programmation by the exemple NI 9237 Getting started.lvprj.
2. In the FPGA VI, add the NI 9237 FPGA while loop (see attached file name FPGA While Loop).
3. Drag and drop the Data FIFO and the subVI folder from the NI 9237 Getting started.lvprj to the NI 9237 Getting started.lvprj.
4. In the RT VI, add the Stop subVI to the case Shutdown (see attached file name Shutdown).
5. In the RT VI, add the Set data rate, Start and Wait subVIs to the case Transition to config (see attached file name Transition to config). Should I put it in the case Config?
Is there any mistake in my procedure?
For the moment, the program does not work because it seems to introduce a fault when I deploy the CompactRIO Controller. If you have any idea of the problem!
