===Slaves===
----
The <b>Slaves</b> section is used to configure new Modbus slave devices. A Modbus slave is an entity that can be called upon by a Modbus master in order to obtain some type of information from it.
 
To create a new Modbus slave, enter a custom name for it and click the 'Add' button. Then click the 'Edit' button next to the slave in order to enter its configuration window.
 
====Slave settings====
----
The <b>Settings</b> section is used to configure the main parameters of the Modbus slave. Refer to the figure and table below for additional information.

A Modbus <b>request</b> is a way of obtaining data from Modbus slaves. The master sends a request to a slave specifying the function code to be performed. The slave then sends the requested data back to the Modbus master.
