PROBLEM TO BE SOLVED: To provide an communication processing system and a method thereof which can effectively use control channels, without increasing the number of wirings, if the control channels are increased. SOLUTION: A servo control system 1 consists of slave devices 20N connected to DC motors 32N and potentiometers 31N which control drive of the motors 32N, a master device 10 which calculates control values which control the motors 32N, and a serial bus signal line SB1 which performs transmitting and receiving of the communication data between both devices; in this system, sensor data, obtained by detecting motions of the motors 32N from the slave devices 20N, are inputted to the master device 10 via the serial bus signal line SB1, the master device 10 calculates the control values which control the motors 32N, based on the sensor information and transmits the control values as communication data to the slave devices 20N via the serial bus signal line SB1, and the slave devices 20N control the motors 32N based on the control values.
