Back-up and Restore Slave Configurations

1 minute read

Synapticon Somanet Drives

To upload the configuration from connected Somanet slaves first log in to the master controller through ssh.

At the command line, first list the connected slave devices:

ethercat slaves

Then 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 (note that the byte order of the drive is reversed so you are actually sending “daol”.
