# Modbus TCP Networking

Networking for Modbus TCP is very straightforward. The Motion Hub must simply be able to communicate with the IP address of the given Modbus TCP device over the network to which the Motion Hub is connected.

Unlike other protocols, Modbus does not provide discovery mechanisms, and so you must manually obtain the IP address of the Modbus device with which you want to communicate via Motion.
