Abstract

PURPOSE:To attain an open and free system design, by using a host computer that controls each terminal device via a center device and adding an interface circuit to the center device. CONSTITUTION:A center device 1 always monitors the input state of a terminal device 3 connected to an exclusive line 2. When the moitor data is requested from a host computer via an interface circuit 5, the corresponding monitor data is fed to the host computer. Then the control state of the load is displayed in more various ways of display for instance. The device 3 is controlled when a control request is given from the host computer. Then the data is transmitted and received on the basis of the style of data that is decided between the host computer and the device 1. The device 3 is monitored and controlled by the host computer.
