Abstract
PURPOSE:To shorten a response time and to reduce the cost, by coupling a management system data way and a control system data way by an exclusive coupling device. CONSTITUTION:A management system data way DW11 for executing the control management, etc. of the whole system, and control data ways DW121-123 for executing a local control under the management of DW11 are coupled by coupling devices 20, 21 and 22, 23, and 24, 25 respectively. The devices 20-25 are provided with a memory 206 for storing sending and receiving data, respectively, and when a data from a transmission line of one coupled DW has been received, whether an address shown by a destination address DA part of said data coincides with an intrinsic address of its own device or not is detected by an address detecting circuit 203. In the event of dissidence, its address is decided to be that of its own DW, and its data is sent out in its own DW through an output switching circuit 204 and a selector 205. When the data coincides with the address of said coupling device in the circuit 203, its address is stored in the memory 206, and the address is converted to a format of the other coupled DW, and is sent out.
