Changing a node address

Hey all, i was wondering i have a SLC500 processor on a DH+ network and i wanted to change it from Node 5 to Node 4? Should i change the node at the processor itself or should i use RSLinx to change the processor???

Any help is greatly appriciated.

I know it can be done at the processor, I'm not sure about changing it in RSLinx as I've never had a need to.

yeah i figured i'd have to change it at the processor, i was just hoping i wouldn't have to stop the program to change it but it looks like i have no choice. Thanks alot for the reply stasis.
