Category: EtherCAT
The Ethercat server appears to be working but cannot connect to the network interface.
You should see something like this
debian@plasma:~$ ethercat master
Master0
Phase: Idle
Active: no
Slaves: 4
Ethernet devices:
Main: c4:62:37:06:66:54 (attached)
Link: UP
Look out for "(attached)" and "Link: UP"
There are several possible reason
- wrong module name or mac address in /etc/ethercat.conf
- network interface is not "up"
- your system uses secure boot, UEFI, ethercat kernel modules can not be loaded. Check some 15 lines down in "sticky", the spoiler section.
