# Modbus Settings Menu

This image shows the Modbus settings screen, which is used to set up and configure your Modbus devices. You can set the following three types of Modbus-specific settings with this screen:

* Modbus address - To change the address used to communicate with the base unit through the Modbus client, set the Modbus address to your preferred value.
* Modbus baud rate - Determines the speed and robustness of communication between these devices.
* Modbus device name - Allows you to quickly identify and manage your Modbus devices, even in complex systems with numerous devices.
