<p>PURPOSE:To save power consumption effectively by permitting a node to the transit to the sleep state when a sleep signal is received from all other nodes even when a mode has a fault. CONSTITUTION:A microcomputer 5 of each node at first discriminates whether or not conditions of setting the node to a wake-up state are finished and sets the node to the wakeup state accordingly when a signal to set the wake-up state is received and implements a prescribed operation. Then the microcomputer discriminates whether or not the node is transited to the sleep state. When the transit to the sleep state is available, the microcomputer sends the sleep signal to other nodes, When the transit to the sleep state is available and the sleep signal is received from all other nodes, the microcomputer permits the transit to the sleep state and allows the node to the sleep state.</p> |
