[etherlab-users] Safety over EtherCAT

[Newell Jensen]

Andreas,

Thanks for getting back to me.  I guess the part I was confused on is how to
properly do the PDO mapping in my application.  For a non-safety slave setup
I know I tell the EtherCAT master what the PDO configuration of the slaves
are.  However, for a safety slave setup I was unsure of how to tell the
EtherCAT master how to copy the safety slave PDOs to the safety master PDOs
and vice versa.  I would have to do this in a cyclic task right?  That is,
once I configure the PDOs, on each cyclic task I would have to read the PDOs
from the slaves and write them to the PDOs of the master and vice versa?

Thanks!
