[etherlab-users] Problem reading SII configuration from slave

[Jesper Smith]

Thank you for this information. I just found out I cannot even set the station 
alias, even from twincat. I hacked ethercat to use a binary eeprom file 
instead of reading it from the slave and that seems to work, aka I can talk to 
the slave.

Regards,

Jesper
