1.2.3 Supports EtherCAT Free-Run and Distributed Clock (DC) mode
EtherCAT telegrams are sent by the EtherCAT master to all connected EtherCAT
slaves. All EtherCAT slaves perform continually synchronous/ asynchronous
sequences of calculations and/or data copying actions.
There are two modes for EtherCAT to do data transferring. One is Free-Run mode
and the other is DC mode.
Free-Run mode
In "Free Run" mode the local cycle is triggered through a local timer interrupt and the
cycle time can be modified by the master (optional) in order to change the timer
interrupt. Local cycle operates independent of the communication cycle and the slave
refreshes the I/O data asynchronous to the master.
DC mode
In this mode, the slave refreshes the I/O data in synchronization with the
communication cycle of the master. Distributed Clocks are used for very precise timing
