See full text

A communication system includes master and slave devices connectable to each other and forming a ring communication path. The master device outputs management data to manage communication along the ring communication path in a CW and CCW directions and receives the management data in the CW direction and in the CCW direction, and outputs, in the CW direction and in the CCW direction, control data to be used by the slave device to control equipment. The slave device acquires a history of transmission of the management data output from the master device and received by the slave device in the CW direction and in the CCW direction, and processes, based on the acquired history, one of the control data output from the master device in the CW direction and the control data output from the master device in the CCW direction to control the equipment.
