Default Configuration

less than a minute

Make changes to the default mcx-rtos etherCAT configuration:

Open ethercat.conf in edit mode:
```
sudo nano /etc/ethercat.conf
```

Note

Make sure that the network device that you wish to assign to the EtherCAT driver is not already taken by the normal network configuration, see wired network configuration.

Modify the network device by changing the following line:
```
MASTER0_DEVICE="eth1"
```
The configured MASTERO_DEVICE, needs to match the configured network device in the EtherCAT Network Configuration.
Modify the driver type by changing the following line:
```
DEVICE_MODULES="generic"
```

Refer to the EtherLAB documentation for a description of all available configuration options.

Save the file and reboot your controller:
```
sudo reboot
```
