j1939 NAME (SPN 2848)

[jh99]

I have two CANs CAN1 and CAN0 hooked to a breakout box
    1 ea, CAN Breakout Box - 14-Port Breakout Box With Power and Termination 
    2 ea, NI USB-8473      - 1-Port, High-Speed CAN, USB Interface 
I have LavView 2013 Ver. 13.0f2 (32-bit)
I am using "c" libraries: C:\Program Files (x86)\National Instruments\NI-CAN\MS Visual C\nicanmsc.lib
which has a "Date created" 3/13/2012 3:35 PM
I think the version number is 2.7.4 but I don't know where to find this number.
I have Windows 7 

I would like to get the J1939 NAME (SPN 2848) for the
NI USB-8473 CAN Interface I have.

I looked in J1939DA TAB: Manufacturer IDs (B10) - Manufacturer ID Codes (Table B10)
and found this for the Mfr ID
529	National Instruments Korea

Is this what is used in the NAME for J1939?

Also I found:

47 Phillips Semiconductor

Since the NI USB-8473 has a "Philips SJA1000 CAN Controller" in it I though that
47 might be the Mfr ID

I would like to use

PGN 60928 Address Claimed 

to request the Address/NAME of the two NI USB-8473 interfaces I have but don't
know what the Address for the two devices I have are or
how to Configure the NAME.

I guess I could use 255 0xFF Global Address and
see if I get anything back.

Thanks

John

Hello jh99

In SAE J1939, the NAME field is used for two main purposes: To identify a J1939 controller application, and also to acquire a source address (SA). The NAME field is transmitted in the data portion of the address claim message, which is PGN 60928. The NAME field is 64-bits wide and contains nine sub-fields. Together these J1939 sub-fields can be used to identify the manufacturer and function of the node. All name fields on a J1939 network, and all sub-networks, must be unique.

Hi Frank:
Thanks for replying to my message.

The setup I have is just two NI-USB 8473's 
Do these have the j1939 NAME in them already?
Do I have to just set them with what ever NAME I wan't to configure and what ever SA (Source Address) I make up?

I was thinking that there may already be a NAME and SA that I could get with a j1939 RQST message some how, but
I'm not sure about this.
While running some of the J1939 example C programs I have CAN1 as 0xAA and CAN0 as 0xBB
but those numbers I just made up.  I though I had to pick Address that were above 0x80 so I wouldn't 
be using Addresses already assigned by SAE J1939.

Thanks

The 8473 wouldn't have the name. This woud be the name of the ECU that you are creating/emulating (i.e., you need to come up with it on your own).

Thanks GPIB_Guru:

I think I will initialize the two NI USB-8473's I have with a NAME that uses Manufacture ID Code 529.
and I think I will try to set one of the SA to 0xAA and the other to 0xBB.
I don't have any reason for the SA I chose other then they are both > 0x80
and it is easy to type two A's or tow B's.

Thanks

John
