7.2 Fast control
Fast control is used to reduce the system reaction time. This means reading
the inputs, processing the data and writing the outputs need less cycles.
Fig.7-4: Timing Diagram
The configuration of the fast control happens in the u-create studio (see on-
line help "Configure EtherCAT slave").
