The Node_Name is the name entered below and refers to the unique combination of the

Node_ID and Port.

The Address is the starting address of the Modbus RTU device. The different address ranges

refer to different input and output types (see the Modbus protocol for details). The Length

refers to the number of data points to be read from the device. The Scan_Interval is the

speed at which we wish to read the values from the device.
