 * __System Operation__ represents the anticipated outcome post the Modbus RTU configuration and the execution of the PLC program based on the developer's designed logic. Consequently, we can observe the device engaging in communication with other devices through Modbus RTU.
 
-The diagram presented shows the uniformity of the Modbus RTU setup across various Arduino devices using the PLC IDE. One main advantage of this system is its adaptability. Regardless of the specifics of the Modbus RTU setup, the PLC program consistently performs effectively. Its design ensures that it can be used in many different environments.
