I assume you are using a National Instruments NI-CAN interface. If that's the case, your best bet is the "NI-CAN Programmer Reference Manual" (installed as a PDF in your NI-CAN folder). This manual documents all of the NI-CAN functions available in LabVIEW and shows the wiring diagrams for how to use each of them. You may also open the VIs from the NI-CAN function palette in LabVIEW and get context-sensitive help by toggling +H.
Another option is to examine the LabVIEW examples that come with NI-CAN. These demonstrate a wide variety of functionality, so you should be able to find something close to what you're trying to do. You can use the examples to get an idea of good NI-CAN programming techniques with LabVIEW, and possibly make minor modificati
ons to suit your specific application.
