6.6.2 Rapid Ring
SW-Ring
TM
technology provides auto-recovery and reconnection 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.
SW-Ring
TM
technology support maximum 250 pieces switches, in which the
SW-Ring
TM
its self-recovery
time is <20ms.
Each port of IES6116 series switch can be Ring Port to connect other switches. When network is broken,
relay for failure alarm will be activated. Redundant organization of
SW-Ring
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. IES6116 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 receive it, then reply a confirm packet to ensure network connection is active. If this setting
will influence self-recovery time, we suggest advanced users can use it.
Basic interface of Rapid Ring as shown in figure 6.6.2:
