Abstract

PURPOSE:To simplify a sequence program by connecting a programmable controller serving as a slave station to an interface circuit for transmission/reception of data to a master station via an interface for control of an input/output unit of a programmable controller serving as the master station. CONSTITUTION:A programmable controller 21 serving as a master station can connect an input/output interface bus to an extended input/output unit 24 via a connection cable 25. While a programmable controller 22 serving as a slave station owns an input/output interface bus independent of that of the controller 21 and using said interface bus to control its own input/output unit and an extended input/output unit 23 based on a sequence program produced by a user inside the slave station.
