if you need synchronous events you can take a look at Distributed Clocks (DC). That way master and clients work with synchronous timestamps
http://www.ethercat.org/en/technology.html#3.3

XFC analog terminals do support DC e.g.
http://beckhoff.com/EL3702/

question is, how to use DC with etherlab ;-)
