PURPOSE:To miniaturize a terminal processor and to decrease the number of sets, by changing over the direction of input/output even if the number of inputs and outputs is different, in a line concentration system of multiplex transmission system. CONSTITUTION:A terminal processor executes the operation indicated by an instruction code in comformity according to the command from a central processing unit via a multiplex transmission line and sets control data in an input and output port 63 or 64. A control circuit 54 of the terminal processor designated from the address code of the control data transmitted from the central processing unit transfers the input and output control data to a register 65 or 66. When a command requesting the monitor data is received, the terminal device only designated with the address code transmits the monitor data to the central processing unit. |
