Hello friends ,

I am new to CAN ,

my query is is there any USB CAN analogus to NI 9881..

Currently NI does not offer an USB based CANopen device. 

There is a PCI-8531 CANopen card if you have a desktop PC with a free PCI slot.

Hope this helps

can anyone tell me that NI 9881 crio CANopen module ,

can be programmed in which layer ,

FPGA ?  or  RT ? or  HOST ?

You can program NI 9881 on the host side. NI 9881 communicates over FPGA but FPGA API is not available for programming. 

You can download CANopen driver and look at CANopen for cRIO example to see how it's setup.

*I am assuming you already have LabVIEW RT, LabVIEW FPGA and RIO driver on your PC.

Hello friends,

can any one tell me how to write raw frame in ni xnet,

I have the hardware as ;

cDAQ 9178

Ni XNET module 9862

I have used the bus monitor to read and transmitt the CAN signal but how to implemwnt the same in vi,

In examples I have seen the CAN raw frame Input as well as Output vi,

my question is I need to put in ; 1  identifier : 0x180

                                                          2  Payload length ; 2

                                                          3  Payload ; 0x80, 0x0D.

if i put the data in vi it says insufficient data...

I'd recommend checking out some of the examples found in Help >> Find Examples.  There are tons of examples on XNet for doing all kinds of things.  The XNet API can be a bit complicated to use at first, but that's because it has so much flexibility.  

Not that you won't find help here, but you might find answers to more specific questions over on the Automotive subforum.
