"WebModbus RTU. MODBUS RTU establishes a serial master/slave communication via RS-232 or RS-485. In order to address the MODBUS RTU, first the serial communication parameters must be known and/or defined. These parameters include baud rate, parity and stop bits. The slave address (es) to be addressed by the master also come into play. " - Modbus tcp/ip addressing
