Yes, this is irritating, correct would be "with a period of 10000 us".

You can watch the period via the variable /your-model/Taskinfo/0/Period.

The PDO indices of the EL4132 changed some time ago, I think we
created a new device type "EL4132v2", please try this one. 

You can watch the process data with the command 'ethercat domain -v'.
For 10 V, there must be a '7fff' somewhere.
