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. scope to look at bladderModbus is restricted to addressing 247 devices on one data link, which limits the number of field devices that may be connected to a parent station (again, Ethernet TCP/IP is an exception). Modbus protocol itself provides no security against unauthorized commands or interception of data.
