The ECAT-2611 is a proven and trusted protocol converter gateway module that allows you to seamlessly inter-connect devices between EtherCAT and Modbus RTU networks. The ECAT-2611 acts as a Slave on both networks, allowing I/O data to be transferred between the two networks.

The ECAT-2611 provides a data exchange buffer that allows two different systems (EtherCAT Master and the Modbus RTU Master) exchange data easily and faster for more diverse applications.
