6.6.7 Device Description file for EtherCAT
The Device Description file contains the specific configuration data of the device. The data must be
known to the controller. The manufacturers of the controller supply the tools for the integration of
the Device Description file into the network. Roland Electronic does not supply such tools, because
they have to be compatible with the interface design of the controller.
The Device Description file is supplied on a CD or can be downloaded from the Roland homepage.
Note
24 Bytes I/O must be set.
