Hi,

is there naybody who know where I can find the CANopen LSS library for AS 6?

2

Do you mean this one? AsCANopen

3

B&R does not offer any CanOpen library which would support LSS

As far as I remember there was an user library capable to do so but I do not remember the name of the library nor who has written this library

Hi Oliver,

thanks for your reply. It’s really annoying that B&R doesn’t support this function. I have a CAN device here that only allows changing the NodeID via LSS.

Do you think I might be able to find the library on GitHub?

You could take a look at : CAN in Automation CiA DSP 305 V1.1.1 document.

You can use ArCan or CAN_Lib to sent and receive the correct can messages.

Hi Corne,

thanks for the tip. My CAN knowledge isn’t sufficient to program something like that, though. Do you perhaps know of an example?

Hi Corne,

I tested the FB ArCanSend() function. It seems the CAN master isn’t accepting LSS commands. I can see the sent frames using a CAN bus sniffer, but it has no effect.
