Hello, I want to read and write commands to protocol Can J1939 and I would like if you can tell me what device I need to communicate with this protocol, or what you recommend to use because I want to send and read the commands from Labview and I want to controller 2 Linear actuators Thomsom so I don't Know what device used to communicate between LabVIEW and actuators Thomson with the protocol j1939.
Thank you.
Regards.

You need to use device providing a CAN port.
I often use simple NI9853 modules…

Thanks for your answer GerdW I Read the Datasheet from NI9853 but we don't have the Compaq RO and want to ask you if I can use this Module USB-8551 PartNumb. 784662-01.

There are no USB-8551 device from NI, but there is a USB-8501 and a USB-8502 CAN device.
The 8501 is a Low speed CAN device. To use this you need to make sure that your CAN bus is not running with a higher speed than 125k baud rate.
I will suggest to use the USB-8502 CAN hardware for your J1939 communication.
Are you planning to program your own J10939 implementation or are use using 3rd party toolkits ?

I would like to use the library from NI, which I found in the NI example with Library from j1939.

Hi Roger,
why don't you call your local NI sales office to have give suggestions!?
I don't use that library (nor did you supply a link), but I guess somewhere in the description of that library there is information on the supported hardware…

Hello, I reviewed the blog from national, and yes the hardware that specific is to CompaqRIO.
thank you for clarified the questions.

Hello,
I am using the National Instrument 8502 CAN module and I want to send the request ID to j1939 to get the data from the xyz sensor. Which sample program should I use?
I am using this program but it is not working.
Thanks.

What is not working ?
Do you get any errors ?
Do you get any data?
Have you seen Hooovahh's CAN Blog ?
There you can learn all about LabVIEW and CAN.
