ancy Fu
nction Is Used
This section takes the following example in which the cable redundancy function is used and a ring
topology is configured, and describes communications statuses during normal operation and in the ring
disconnection status. The configuration example contains three devices in the ring topology.
Normal Status
All slaves are in communication.
Ring Disconnection Status
Although the ring is broken between Slave C and D, all slaves continue communications.
Stop Device X to Z and then turn OFF the power supply to the EtherCAT master. Fix the ring discon-
nection status by replacing the cable, and then turn ON the power supply to the EtherCAT master
and to the devices, which returns the system to the normal communications status.
