摘要： In duplicated equipment including main equipment, duplicated subordinate equipment, and a communication line for transferring data between the main equipment and the duplicated subordinate equipment and for sending a changeover signal which can put one and the other of a pair of subordinate devices making up the duplicated subordinate equipment in an active state and a standby state, respectively, from the main equipment to the duplicated subordinate equipment, each of the subordinate devices includes means for putting the other subordinate device in the standby state, to prevent both of the subordinate devices from being put in the active state when a failure occurs on a transmission path between the communication line and one of the subordinate devices.
