[etherlab-users] Master0 dead

[Gavin Lambert]

The "waiting for devices" state means that no network devices are available for EtherCAT yet.

You need to check your configuration file (if you're using SysV /etc/init.d/ethercat then the file is /etc/sysconfig/ethercat; if you're using SystemD ethercat.service then the file is /etc/ethercat.conf).  You need to define both the driver module to use (which one depends on what network interface you have) and also define the MAC addresses of each interface that should be used for EtherCAT communication.
