If I have Codesys project with CANopen manager and I add a CANopen slave node to the CAN with node id 19, the system is clear to me.

But if I add two sensors (they are identical) devices with same factory preset nodeid 19, how do I change the nodeID of either of them?

I do not have any idea. Devices support LSS-service (but I dont have idea how to implement nodeid change with or without it).

Should I code it or should the canopen manager change the nodeid somehow. Now I have set the new node id with SDO (there are manufacturer set parameter to bet set so it changes the nodeid), but doesn't it change both sensor nodes if they are on the same CAN.

Any ideas are welcome.

Of course I could change it by adding first device to the CANand change it and after that I could add the second one to the CAN bus. But I want to change the dynamically when both are in the CAN bus same time so it should be same situation as in future production line.

Do you have a link to the manual for the sensors?
