Rockwell Automation Logix5000 Controllers Messages Programming Manual - Manual (Page 24)

Chapter 3 Send a message to multiple controllers
Although not required, it is recommended that you add the communication
modules and remote controllers to the I/O configuration of the controller. This
makes it easier to define the path to each remote controller.
For example, once you add the local communication module, the remote
communication module, and the destination controller, clicking Browse lets you
select the destination.
