Hi,
I have successfully tested the tty example from ethercat master, but it is
designed for a kernelspace cyclic task only.
How can I modify this example to use a Beckhoff EL6002 with my ethercat cyclic
task in userspace ?

Hi Marcel,
In my opinion a 70 us jitter is a very good number.
I have run some tests in November 2011. It was different from you, because I
measured the whole chain latency and not only the PC performance.
Indeed, I wondered how many time is required to trigger an action after reading
an event

Unlike Beckhoff terminals, servo drives are very complex ethercat slaves.
Often you have to send SDO commands to the servo drive to configure PDO mapping.
After that you can communicate with the servo drive with PDO.
