Fieldbus coupler supports Ethercat

May 2011 Fieldbus & Industrial Networking

In response to the growing demand for fast, real-time control units, Wago has added an EtherCAT fieldbus coupler to its Wago-I/O-System.

The new coupler allows the user to implement EtherCAT applications, while benefiting from the high flexibility of the Wago-I/O-System.

The 750-354 EtherCAT fieldbus coupler boasts a very powerful data transfer capability. It identifies the connected I/O modules and generates data for the relevant application. During EtherCAT telegram processing the system extracts only the relevant data from the telegram, while the coupler completes the required process data.

A special EtherCAT communication unit, consisting of an EtherCAT slave controller (ESC), controls the entire data exchange with the EtherCAT master. High transmission speed and data exchange reliability are achieved by transferring lower communication levels into hardware. Mailbox,cyclic and acyclic data can be transmitted and processed via CAN-over-EtherCAT (CoE). Easy and time-saving commissioning of the fieldbus coupler is achieved by using automatic address assignments together with the EDS file integrated into the engineering tool of the EtherCAT master.

Both line-in and line-out RJ45 connectors are located on the front of the coupler, providing easy configuration of line structures.
