Does canopen_chain_node create local node? [closed]

edit

Does the canopen_chain_node create a "local" node on the pc with its own object dictionary or does it just manage the nodes on the bus (ex. motors), as it can be used as a stand-alone ROS node.

I have struggled with understanding the canopen_chain_node and I am realizing that I might have misunderstood what i actually does. I would like for it to create a canopen node on my ROS-pc with its own object dictionary, which i can set up using eds files and read and write using the services get_object and set_object.

But does get_object and set_object just use SDO's to read and write from other nodes on the bus, instead of reading from a local object dictionary?
