USB-8476 No LIN Slave Data -- Fixed!

[Tom_Brackman]

Hope this helps others bypass the troubles I had.  A quick Thanks to Jonathan B. of NI App. eng. for suggesting another LIN example that led to my solution!

Equipment:  Automotive Battery with single wire LIN connector using protocol ver. 2.1. & Baud Rate = 19200.  (LabVIEW 2014, NI-CAN ver.14, and a USB-8476 LIN interface)

Modified Example "LIN Master Send Full Frame and Receive.vi"

Bottom Line:  changing the "Is Remote" input to mode 17 on "ncWriteNet.vi"!   Also had to add another "ncSetAttr.vi" with the LIN Checksum Type ID set to "1" for Enhanced (needed for version 2.1).

In my case I consistently get two Error frames in the beginning, so I enable "Log Bus Errors" (easy way out of error handling) and throw away the 1st 2 frames.  And "Arbitration ID" is my frame ID!  I needed both 0 and 1 (2 frames to get the full data).  Also found that my vi works for either state of "Termination" and "Self Reception".  Also the "Data" input to "ncWriteNet.vi" didn't matter so I was able to remove the input array.  Make sure the LIN"x" interface number matches the number found in NI Meas. & Auto. Explorer.

Good Luck,

Tom
