Abstract
PURPOSE: To effectively use the unit, by increasing the occupancy rate of the central control unit and terminal control unit and decreasing the terminal control instruction delivery circuits, through making the terminals of plurality controllable with a single instruction.
CONSTITUTION: The terminal address during instruction to the terminal control unit ATTD constitutes with the pattern possible for a plurality of terminal designation, constituting it with code or the combination of the code and flag. In one case, when the terminal address code A is inputted, all the terminals belonging to the group A are designated and if the code B, all the terminals belonging to the group B are designated. In other case, n sets of flags are placed next to the code part, and if the code section is made as A, B, and C, broad terminal designation can be made with the code and flag in a short digit, and the terminal designated is arbitrary and a variable number. Accordingly, for example, the corresponding ATTD to the code number is selected with a single instruction made from the central control unit CC and to the terminal unit corresponding to the flag number, the same information can simultaneously be controlled.
