ABSTRACT:
A system is provided to enable communication between a plurality of terminal devices and a central device connected thereto. The central device includes a communicating element which takes initiative and performs communication with a plurality of terminal devices in a predetermined order by scanning the same and also detects any abnormality of a terminal device in communication therewith. An abnormal terminal table is provided in the system for registering any abnormality of any of the terminal devices. The system contains an element for checking whether an abnormality is registered for a particular one of the terminal devices by reference to the abnormal terminal table. Communication is established with that particular terminal device, the checking element then generating a corresponding output. A control element is provided responsive to the output of the checking element to cause communication processing with that particular terminal device when no abnormality is registered. The control element also causes the checking element to check the next terminal device for abnormality registration when any abnormality is registered, a registering element also being provided to register any detected abnormalities in the abnormal terminal table. In one aspect of this invention, the central device also includes a display unit for displaying data pertaining to a terminal device detected as having an abnormality.
