摘要：

<p>PURPOSE:To collect fault information without any influence on exchanging processing by collecting the fault information of a remote station device by a preliminary communication link in the title system equipped with a parent station device to control the remote station device connected by a dual communication link. CONSTITUTION:For example, when a fault occurs in the software of a remote controller 6 while a main controller 2 of a master station executes an exchange with the remote controller 6 of a remote station by a communication link 4, the controller 6 is switched to a remote controller 5, the state of a main controller 1 is made into an operating state through a communication link 3, and restart processing is executed. After that, the controller 6 reads the fault information in its built-in memory, the fault information is transmitted to the controller 1 using the link 4 which becomes a preliminary link, and the fault information can be collected without any influence on the exchanging processing.</p>
