Log into the system from the console using a screen or keyboard or through ssh as described in Remote Access & File Transfer.

At the command line, first list the connected slave devices:
```
ethercat slaves
```
Use the correct slave id to upload the configuration file from the slave:
```
ethercat -p [ID] foe_read config.csv > config-backup-[ID].csv
```
Where [ID] is the slave id. The ethercat command outputs the contents of the file on stdout so this is redirected to a file, in this case config-backup-[ID].csv.

To restore a backup type:

ethercat -p [ID] foe_write -o config.csv config-backup-[ID].csv

Once the file is copied to the drive the drive needs to be told to reload its configuration from the file:
```
ethercat download -p [ID] -t uint32 0x1011 0x1 0x64616f6c
```

The value 0x64616f6c hex is actually ‘‘load’’ in ASCII.

The byte order of the drive is reversed so you are actually sending ‘‘daol’’.
