Introduction to Industrial Ethernet Switches

The two devices connected in the configuration exchange data frames with each other to synchronize their operating statuses (one device is master and the other slave). If there are no problems, only the link from the master to the other network segment is active. If this link fails (for example due to a link-down or a device fail- ure), the slave activates its link as long as the problem persists.
