2.7 X-Ring 

Application 

 

The industrial switch supports the X-Ring protocol that can help the network system 
recover from network connection failure within 10ms or less 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. 
 
1.  The X-Ring is supposed to recover from connection failure within 

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