Redundancy
7.1 Rapid Ring
7.1.1 SwRing
SwRing
TM
technology provides auto-recovery and re-connection mechanism for
broken network. When network is broken, it has link redundancy and self-recovery
capability and self-recovery time is less than 20ms. SW-Ring is the patented
technology of 3onedata Co.,Ltd. designed for industrial control network requiring high
reliability.
SwRing
TM
technology support maximum 250 pieces switches, in which the
SwRing
TM
its self-recovery time is <20ms.
Each port of Switch can be Ring Port to connect other switches. When network is
broken, relay for failure alarm will be activated. Redundant organization of
SwRing
TM
enable backup link to recover network instantly.
Self-developed patented technology for SW-Ring network can realize the intelligent
redundancy for industrial Ethernet switch, which can make you easily and
conveniently establish redundant Ethernet, and can facilitate the quick recovery of any
network section of automatic system disconnected from the network. Switch supports
maximum 4 ring groups. Each group set up 2 ports as Ring Port and a port cannot
belong to several rings.
Hello_time setting is time interval of sending detecting packet to network at regular
time. The unit is ms. Its main purpose is to detect network connection. It sends a
detecting packet to next door devices by CPU. If they receive it, then reply a confirm
