PURPOSE:To attain multiple address information near at the same time with a time difference through a multiple address instruction from a processor by providing a multiple address controller connected to a terminal equipment group via a data link. CONSTITUTION:The multiple address controller 4 receives a synchronizing control instruction from a main processor (MP) 2 via a communication bus 5 and the received instruction is informed to plural terminal controllers 7 via the data link 6 in terms of multiple address. The data link 6 accommodates plural terminal controllers 7 and the multiple address controller 4 to apply eachange connection by the control of the MP 2. The terminal controller 7 is connected at each terminal equipment 8 to control the terminal equipment 8 according to the instruction of a local processor (LP) 1. In the inter-MP exchange processing task, the multiple address control processing is not executed between the MP and Lp processing but executed by the instruction from the MP 2 to the multiple address controller 4. Thus, the multiple address control to the plural terminal controllers 7 is executed by one processing.
