Tips: What is industrial Ethernet switch ring network redundancy?
Ring network is to use a continuous loop connecting each device together. It ensures that the signals sent on one device can be seen by all other devices on the ring. Ring network redundancy refers to whether the switch supports: When the cable connection is interrupted, the IE switch receives this information and activates its backup port to restore network communication. At the same time, the industrial Ethernet switches disconnected from ports 7 and 8 in the network, the relays are closed, and the indicators give an error alarm to the user. After the cable repair is normal, the relay and indicator light return to the normal state.
