Master interface for EtherCAT-capable network device drivers.
|
|
Through the EtherCAT device interface, EtherCAT-capable network device
|
|
drivers are able to connect their device(s) to the master, pass received
|
|
frames and notify the master about status changes. The master on his part,
|
|
can send his frames through connected devices.
