Abstract

PURPOSE:To detect as to what kinds of units are disposed to each address, by receiving an intrinsic information sending demand signal from a program processor, and by sending an intrinsic information displaying the kinds of the units. CONSTITUTION:A program processor CPU assings address in accordance with a program, and sends and receives data among input and output units U1-Un. When inspecting as to whether or not a fixed unit is connected to each plug P1-Pn, the program processor CPU sends the address information of a unit to be inspected to an address bus AD, and sends an intrinsic information demand signal SDR. Intrinsic information generating means ST1-STn for generating intrinsic informaftions dispalying the kinds of each unit are mounted to each unit U1-Un, and each unit sends intrinsic informations to the program processor CPU when receiving the intrinsic information demand signal SDR.
