Abstract

PURPOSE:To achieve correspondence even at emergency, by providing addresses other than assigned ones as required, in the control assigning addresses to each of a plurality of terminal devices. CONSTITUTION:A central monitor controller 1 sequentially generates address signals. A terminal device 2 compares its address with an address signal to be given and if they are coincident, the data can be returned. If a load of the central monitor controller 1 is increased and a time interval accessing each terminal device is longer, some terminal devices receive inconvenience. Those terminal devices switch their address into emergency address. The controller 1 accesses the emergency address more frquently than normal addresses in advance. As a result, a required service can be achieved to specific terminal devices.
