(a) The High-speed Analog Input Unit reads the input changed times.
Offset between Sync0
and the timing to read
inputs
This period of time is
automatically
calculated by the
Sysmac Studio.

(b) The Communications Coupler
Unit reads the input changed
time that is read by the Unit
and the input value at this
point of time at I/O refreshing.
