specified device (NI 9881 CanOpen) is not present or is not active

Hey guys,

I'm working on a cRIO 9045 with the CanOpen Modul NI 9881. I changed the program mode of this module in the MAX from FPGA (default value) to Real-Time. After that I got an error message pictured in the attachement. I can't find information regarding this error code. Pressing the reset button in the MAX doesn't help.

Do you know how to solve this problem to work with the CanOpen modul again?

Thanks

Hey, stef an

Have you installed the NI-Industrial Communications for CANopen and Real-Time Module?

Also make sure that you have installed same versions of them.

You can also have an unsupported drivers installed for your cRIO and 9881

How can I check this? I don't think thats a problem of an unsupported driver due to the fact that the error poped up after changing the program mode of the 9881 to Real-Time mode.

Hi Hamlet,

thanks for your response. I have installed LabView 2018 SP1, NI-RIO 18.5 and the NI-Industrial Communications for CanOpen 18.0.0
