ABSTRACT:
A terminal device for outputting control signals and receiving sensor outputs is equipped with address setting terminals for setting an address of the terminal device. The address information at the address setting terminals is supplied to a decoder which decodes an input/output function or mode setting signal. Input/output functions of input/output terminals are set by the address information by controlling output buffer circuits which transmit the signals of the input/output terminals, in accordance with the decoded input/output function setting signal. The address setting terminals are shared by the address terminals and the input/output function setting terminals to that the number of terminals can be reduced.
