requirements and for timing signals that can be generated independent of the
communication cycle.
In this mode, a mechanism called a Distributed Clock (DC) is used to synchronize
EtherCAT communications. The clock is shared to synchronize the master and the
slaves. Interruptions (Sync0) are generated in the slaves at precise intervals based on
this clock. Each slave executes I/O processing at this precise time. This means
that all EtherCAT devices can share the same EtherCAT system time (global time
base) for synchronization.

Note!
If EtherCAT master accesses ADAM-5000/ECAT with analog input / output modules ,
there is ADC/DAC limitation in the existing module hardware design and can’t support
read/write data through local bus in specified short communication cycle time. Master
will not acquire the right information before data completely transferring. For the
low-response module like A I/O, ADAM-5000/ECAT can dispatch write command or
response prior-time of data.
1.2.4 Supports EtherCAT SyncManager mode
EtherCAT provides a mechanism to synchronize slave memory access. Because the
memory of a slave can be used for exchanging data between the master and the local
application without any restrictions.
Since both the EtherCAT network (Master) and the PDI (Slaves) access the DPRAM in
the ESC, the DPRAM access needs to ensure data consistency. The SyncManager
