EtherCAT
the master (as per IEEE 802.3) is not first received, then interpreted and the
process data is not copied at every interconnection, as is the case with other
industrial Ethernet solutions. The EtherCAT slave devices read the data rele­
vant to them as the telegram passes through the device. Input data is also in­
serted into the telegram as it passes through the device. Thus a frame is not
fully received before being processed. Instead the processing starts as early as
possible. The send process also begins with a minimum time offset of only a
few bits. The master is supported by a standard Ethernet controller.

Configuration

The majority of the work required for implementation is usually done by the
configuration tool. Clearly defined interfaces have been created to minimize the
required effort. The configuration tool learns the device properties from the
Device Description XML data set (EtherCAT Slave Information File = ESI).
Then the configuration tool generates an XML data set containing all relevant
information about the network topology, arrangement of process data, start-up
and diagnosis. When the master is actually implemented, this data set only
needs to be loaded, and for starting and operating the network the required
Ethernet frames have to be extracted.
