AMT58x-EC EtherCAT®
Synchronous with DC SYNC0
In this operating mode data is sampled and then copied into Sync
Manager buffer simultaneously at SYNC0 event generated by the
ESC capture/compare unit.
Time required for accomplishing these operations is set in object
parameter; in particular object 03 Shift
1C33 Sync Manager input
Time (1C33hex, sub3) and object 06 Calc and Copy time
(1C33hex, sub6).

Jitter
Input Latch
In this operating mode "Jitter" is a fundamental parameter in the
sampling of two consecutive data. The main advantage of this mode
is that there is a direct relation between the sampling instant and the
absolute time of the system; in this way, if we know the shift times of
the Slaves, we can have an exact image of the system at a given
moment (with a tolerance equal to jitter).
