[etherlab-users] slave not change to op state

[殷士龙]

Hey, I am tring to use igh ethercat master but meeting a trouble.
My slave is a servo drive and it supports ethercat communication.
I set my slave information and pdos from early and in cycle task just read data from TPDO.
But when I run it, I find the WC recevied was always zero and the AL state showed in PREOP.
I could see the slave was touched, but how could this happened? My pdo setting have something wrong?
Who can tell me the possible problems? Thank you!
