PURPOSE:To obtain a constitution system which is controlled easily and flexibly, by allowing the independent control of respective terminals from a terminal controller side and permitting one slave CPU to control plural terminals on hardware. CONSTITUTION:A terminal controller 1 has a main control part 5 including a master CPU and a memory 6, and is provided with a transmission control part 8 which is connected to a console control part 7 for controlling a console 2 and a circuit 3 to control data transmission to a terminal device 4. The terminal device 4, on the other hand, has plural terminals I/O-1, I/O-2, and I/O-3, which are connected to I/O control parts 9, 10, and 11 respectively. The terminals I/O-1 and I/O-2 are both controlled by a subcontrol parts 12 and 13, and the terminal I/O-3 is controlled by the subcontrol part 13. The subcontrol parts 12 and 13 have slave CPUs and memories 14 and 15, and are connected to the line 3 through transmission controllers 16 and 17. |
