2.6 X-Ring Application

The industrial switch supports the X-Ring protocol that can help the network system recover from
network connection failure within 10ms and make the network system more reliable. The X-Ring
algorithm is similar to Spanning Tree Protocol (STP) and Rapid STP (RSTP) algorithm but its recovery
time is less than STP/RSTP. The figure below is a sample of X-Ring application.
Note The Ethernet switches with firmware version before v3.0 use the X-Ring
function that has the limitation as follows. However, the one with firmware
version after v3.0 (included) use the X-Ring Pro function that gets rid of
the limitation.

10ms when the amount of the connected devices of the X-Ring group
is less than 50.
