PROBLEM TO BE SOLVED: To provide the transmission method of a communication data block for controlling re-starting of all slaves surely in a communication system, in which a master and two or more slaves are connected in a ring form. SOLUTION: The transmission method of the communication data block is provided with a step 1 in which a master transmits a preparation command of re-starting to all the connected slaves, a step 2 in which a re-starting flag on the self memory is turned on through a command code by the slave and a response code is added to the command code and the transmission is carried out, a step 3 in which the master determines the completion of the preparation of the re-starting through the response code from the slave, and a step 4 in which the master transmits a command for implementing re-starting to the slave. By using the re-starting preparation flag and the response code, the re-starting of the slave can be controlled surely. COPYRIGHT: (C)2006,JPO&NCIPI
