4.4 Device profile
The device profile describes the application parameters and the functional behavior of
the device, including the device class-specific state machine. With EtherCAT you do
not develop individual device profiles for device classes. Instead, simple interfaces are
provided for existing device profiles:
The measuring system supports the
CANopen-over-EtherCAT
(CoE) mailbox
protocol, and consequently the
"Device Profile for Encoder"
, CiA DS-406, known
from CANopen.
