Abstract

PURPOSE: To make it possible to set and change addresses freely by cascading many I/O devices to a processing unit and setting respective addresses freely in respective I/O devices.
CONSTITUTION: Address data sent from transmission cable 4 is input to address decoder 7 in I/O device 1 and is decoded, and meanwhile, an address set in respect to this I/O device is set to digital switch 5 previously, and receiving address data of the address decoder 7 output and set address data of the digital switch 5 output are detected for coincidence by coincidence circuit 8; and when coincidence between both addresses is discriminated, it is detected that this I/O device 1 is called, and main gate 9 and multiplexer 10 are operated to connect directly data between I/O part connected to I/O points 2... and transmission cable 4.
