It is the "EtherCAT telegram" stored directly in an Ethernet frame that exchanges data regularly
between the EtherCAT Master Unit and Slaves.
Each "EtherCAT telegram" is configured with telegram header (data length, including address of one or
more Slaves, etc.), data, working counter (check bit).
When an Ethernet frame is compared to a "train", an EtherCAT telegram can be considered as "railway
car."
