5-9-5 Relation between the Network Configuration Information and the Actual Configuration
The following example shows a case of No. 4. In this example, the communications status changes
from the normal status to the ring disconnection status, and then the power supply to Device Y is turned
OFF, which turns OFF the power supply to Slave C to E and causes a minor fault. Slave A, B, F, and G
continue communications even after the minor fault occurs.
