Abstract

PURPOSE: To transmit processing data to terminal stations in parallel in a high speed by detecting the I/O state between terminal stations and a central control station by the read output of a memory and performing data input/output between an internal bus and an I/O bus by this detection output.
CONSTITUTION: Plural terminal stations 12 including process interface part 14, which transmits or receives data to or from processing unit 11, and operatable machine interface part 15 and central control station 17 storing a microcomputer are connected by I/O bus 16. Here, station 12 is provided with interface part 32 to detect that the station is selected by address information, and data input/output between the station inside and the address bus is performed. Meanwhile, station 17 is provided with interface part 31 to detect the I/O state between stations 17 and 12 by the read output of a memory, and data input/output is performed between the internal bus and I/O bus 16 by this detection output.
