5.7 Redundancy
5.7.1 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 IES618-4D series 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.
IES618-4D series 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
