PURPOSE: A signal distribution processing method of an operation system in a network is provided to allow each operation system to easily detect a processing order of received signals in a distributed processing network structure and to be easily admitted into and withdraw from the network. CONSTITUTION: Values of blocks in a time stamp(40) are set to (0,0,0,0). In this state, when an operation system desires to transmit a signal, it should set the time stamp(40) to (0,1,0,0) and provides the time stamp(40) together with a predetermined signal to operation systems. When the operation system(13) desires to provide a predetermined signal to the operation systems at a point(T2), it should set the time stamp(40) to (0,1,1,0). That is, after receiving the time stamp(40), if each operation system desires to provide a predetermined signal to the other operation systems, each operation system changes a value of a block allocated to itself in the time stamp and outputs the changed value. Accordingly, each operation system can easily recognize the order of providing signals by using the received time stamp. In addition, each operation system can withdraw from a network or a new operation system can be admitted to the network as necessary. When the operation system desires to withdraw from the network, it provides a withdrawal signal to the other operation systems. The withdrawal signal contains an ID(B21) of the network to which the operation system belongs, and information on how many times the operation system has withdrawn from and been admitted into the network(B22), and how many signals the operation system has outputted(B23).
