PURPOSE:To efficiently operate a terminal control device even when there is a limit in the using range of a device address by initially causing a terminal equipment number and a picture number to be an unusing condition, successively registering the terminal equipment number and picture number when an on-line work is started and causing the numbers to be the unusing condition when the on-line work is ended. CONSTITUTION:The device address to be added to a message in order to clear the address or sending destination of the message which is transmitted and received with a high order device and a device address table to show correspondence between a terminal equipment number A and a picture number B are equipped. The terminal equipment number A and picture number B are initially caused to be the unusing condition and when the deceleration of the on-line work start is executed, the terminal equipment number A and picture number B are successively registered. Then, when the declaration of the on-line work end is executed, the numbers are caused to be the unusing condition. Thus, even when there is the limit in the using range of the device address, the terminal equipment can be efficiently operated. |
