Star Connections
Star connections allow you to connect slave stations through Hub Modules. Each port on a Hub Module connects to only
one slave station. You can also connect one additional Hub Module to the first Hub Module.
Note: 1. Terminating resistors are not required.
2. The maximum number of stations that you can connect with star connections depends on the communications cycle.
