function application. A sample application of the industrial switch is shown as below:
4.1 X-Ring Application
The industrial switch supports the X-Ring protocol that can help the network system to recovery
from network connection failure within 20ms or less, and make the network system more reliable. The
X-Ring algorithm is similar to spanning tree protocol (STP) algorithm but its recovery time is faster
thanSTP.ThefollowinggureisasampleX-Ringapplication.
