The ECX-EC EtherCAT bridge merges two EtherCAT slave segments. In this way process data between two independent EtherCAT networks can be exchanged. For the synchronization of different cycles (DC) the bridge uses the exact difference between two slave time stamps as CoE object. Thus, one master is synchronized with the other. Within a redundant network the ECX-EC bridge uses the first and the last slave simultaneously which allows the master to keep all slave segments synchronous in both segments.
The EtherCAT implementation relies on Ethernet ports acc. to IEEE 802.3, configuration is effected via CoE objects and the firmware update as well as the EoE support (switch port) is performed via FoE. The EtherCAT process image can be configured by means of typical network configuration tools ( i.e. esd workbench, TwinCAT).
