S3EC Sercos/EtherCAT-Bridge

With the Sercos/EtherCAT-Bridge it is possible to connect Sercos and EtherCAT masters and to transmit data bi-directional in real-time within heterogeneous real-time Ethernet communication structures.

The Sercos/EtherCAT-Bridge apperas on both busses as I/O device. The length of the real-time data is adjustable in the range of 32 to 2048 bytes and can be adapted to the needs of various applications. Copying the data between the two buses is supported by hardware and is executed within one communication cycle.

In addition to the application-specific I/O data, information about communication status and diagnostic data of the Sercos or EtherCAT bus is transferred to the respective other side. This allows a fast reaction of the two masters on changes of the communication state or on error events.

Beside the real-time data channel the device also supports a bi-directional channel for asynchronous data transmission. On the Sercos side this mailbox mechanism is represented by IDNs which are readable and writeable over the service channel. From the EtherCAT side the mailboxes are accessible over CoE objects or VoE protocol.

The device is carried out as compact module for DIN-rail mounting. For both Sercos and EtherCAT two RJ45 ports are available. A further RJ45 connector at the front side serves as standard Ethernet port. Over this interface, standard Ethernet devices can communicate with other devices connected to the real-time busses using the respective mechanisms (UC channel and EoE protocol). The IEEE 1588 master also available on this interface can be used for clock synchronization.
