hi,

maybe there is a bug in the vi named Convert CAN Arb ID to J1939 ID.vi  

its path in the package is……CAN_Message_Online\J1939 Multi Packet Frame\Code\J1939 Utilities\_SubVIs\Convert CAN Arb ID to J1939 ID.vi

when the PF is smaller than 240(10), the PS in the PGN should be 0.

Can I get these examples in version 8.5?

It would be nice if NI had a J1939 driver or add-on that would work with both the frame API and/or the channel API.  The only examples provided for J1939 here are based on the frame API, which precludes you from using the channel API with a CAN database on the same port.  The channel API is a very time saving feature for most applications.

DMC recently developed a set of J1939 protocol drivers for LabVIEW which are based on the NI-CAN channel API.  The drivers are written in LabVIEW just like the example, but provide functions at a layer above the base CAN channel API layer.  This allows the simultaneous capture of data from both J1939 packets which are simple broadcast CAN frames, or more complex transport using BAM, including extended data frames.

Although it would be nice to have an option like the Automotive Diagnostic toolkit, which worked withouot forcing a user to pick an API and stick with it for J1939 and whatever else they have going on with that CAN port.

Correct link for J1939 protocol drivers for LabVIEW which are based on the NI-CAN channel API.

Customers have recently requested that a J1939 Reference Example be provided for the new sbRIO-9606, which uses the RIO Embedded CAN driver.

Hello , i am using the NI 9853 to communicate with a charger that use J1939.

With the project J1939 cRIO Example Project.lvproj when i send the message appears  the message code -63001-Invoke Method: FIFO.Write in J1939 cRIO Example.vi .

How can i solve this error??

Thank you
