I am trying to read the CAN signals from a vehicle using the CAN Signals Receive (Host) and CAN Signals Receive (FPGA) example vi's. I am using Labview 2013 with the FPGA Module and my hardware consists of a Compact RIO NI 9146 Expansion chassis with an NI 9853 High Speed CAN Module. The FPGA vi seems to be working like it is supposed to, the host vi seems to be having a problem converting the frames to a signal. In the host vi I click the arrow on the "signals list" and choose the "browse for database" option and then upload the database for the vehicle. When I run the vi's, though, I don't get any values other than zero on the "CAN Signal" indicator. Several of the channels will show the value of the offset in the database, but several other channels which have offsets still show zero.
When I go into the host vi block diagram and open up the NI XNET sub vi that is supposed to "Convert the array of U32 to Signals" it opens the front panel for the XNET Convert (Frame Raw to Signal).vi Front Panel. While running the vi, the "frame data" indicator is displaying the values coming in on the CAN bus but I don't get anything other than zero (or the offset value of several of the channels) displayed in the "signal data" indicator. After opening the block diagram of the XNET Convert vi there is a note stating not to change anything.
Is anyone able to help me figure out why I am not getting any signal data?
Thank you.
