 #### Modbus RTU Server Portenta Machine Control
 
 To configure the Portenta Machine Control as a Modbus RTU Server, navigate to the `RS485 SerialPort` tab in the `Resources` panel within the PLC IDE. It will open a `Modbus Configuration` window where you should choose the `Modbus RTU Slave` setting. For the tutorial example, we will employ the following properties for the server Portenta Machine Control:
 
-- Port type: `RS485`
-- Baud Rate: 19200 b/s
-- Serial Mode: N,8,1 (No parity, 8 data bits, 1 stop bit)

 To establish communication with the pre-configured Modbus RTU Server Portenta Machine Control, add a Modbus node by right-clicking the `RS485 SerialPort` tab within the `Resources` section. Once ready, you will see an 'Add' option. Use this to insert a 'Generic Modbus' node. For this example, configure the node with the following parameters:
 
-* Name: PMC_RTU_1
-* Modbus address: 10
-* Minimum polling time: 1 ms
-* Address type: Modbus
-* Swap words mode: Little-endian compliant (No words swapping)
