Abstract
An electronic wiring system using automatic cyclic communication means in which having a center apparatus including a "state machine capable of controlling the receiving-and-transmitting of data by driving associated circuits without recourse to communication control programs, and a memory to store data; and a plurality of terminal devices connected to the center apparatus via a digital communication line. Each terminal device is connected to an associated object to be controlled by the center apparatus, and has no microcomputer associated therewith. The terminal device is capable of self addressability. Each data bit group in the memory of the center apparatus is structurally same as the data bit group in the I/O port of the terminal device.
