hi there, I have installed NI-CAN 18.5 driver, but I don't find the canopen library, so anyone can help tell me how te get the canopen library, thanks

Hi Barry2018,

NI-CAN and NI-CANopen are two different products. If you want to find the canopen library, you need to install the NI-CANopen driver.

Thanks!

Hi,

You can download the ni canopen driver from here:https://www.ni.com/zh-cn/support/downloads/drivers/download.ni-industrial-communications-for-canopen....

Thanks!

hi, 

I download canopen1500 driver, but after install it, I cannot find the canopen file or canopen.llb, do I need insert the can card into my PC, or where I can find it? thanks

Hi,

which version labview is installed on your PC? The canopen 15.0 only supports the LabVIEW 2015/2014/2013/2012. And you are able to find the canopen lIb in the path: ..\National Instruments\LabVIEW 2018\vi.lib\CANopenLib after you have installled the CANopen driver.

Thanks

hi zhengchen, i'm using labview 2019, so I update the canopen driver to 19.0, but I still don't find the canopen file.......

I'm pretty sure that canopen.llb comes from the very old CANOpen VI Toolkit library that was based on the old NI-CAN API. As such it probably won't be trivial to use that with modern hardware. I believe that there is a way with modern CAN interfaces from NI to install a compatibility layer that will support NI-CAN in a limited way and that may be enough for this driver to work but I never tried.

The only download I could find for the old CANOpen VI library was here: https://www.ni.com/nl-nl/support/downloads/software-products/download.canopen-library-toolkit.html

hi ,

it is just help doc for canopen, there is no driver/api could be download, thanks

[rolfk]

Yes, as it is rather old software they apparently pulled that. It also wasn't free but a paid Toolkit so you never could just download it like that. It may be still available from NI if you ask the right person very nicely but it may just as well be one of many discontinued products.

The recommended and supported way is to go with the newer Industrial Communication for CANOpen driver that you already seem to have installed. Sorry I"m not aware of a simple compatibility layer driver that simulates the old CANOpen library on top of the new Industrial Communication driver.
