The EtherCAT DeviceDesigner is available for download here.

The EtherCAT DeviceDesigner is an easy to handle tool for the fast and cost-saving creation of EtherCAT devices. The tool supports both the EtherCAT Slave Stack Code ET9300 by Beckhoff and our EtherCAT Slave framework.
The CoE object dictionary can be created with a few mouse clicks based on predefined profiles and also the characteristics of the objects can be configured in a fast and easy way. The EtherCAT DeviceDesigner creates the object dictionary and initializing functions in C source code, an electronic data-sheet in XML format and the device documentation.
