• The High-speed Analog Input Units perform conversions in order to obtain the input values of the
final analog input data sampled, before the timing to read inputs.
The timing of starting the AD conversion in the first sampling is the same for all channels of the
High-speed Analog Input Unit. (Refer to (b) in the figure below.)
Similarly, for all channels of the High-speed Analog Input Unit that perform the same number of
samplings, the timing of starting the AD conversion in the second and later samplings is the same.
(Refer to (c) in the figure below.)
• The Communications Coupler Unit reads the analog input values, which are read by the Unit at the
timing of reading inputs, at immediate I/O refreshing. (Refer to (d) in the figure below.)
• The interval of I/O refreshing varies with the processing conditions of the Communications Coupler
Unit or the host communications master. (Refer to (e) in the figure below.) The timing to read inputs
will be at a fixed interval. (Refer to (f) and (g) in the figure below.)
• The Sync0, the timing to read inputs and the maximum NX bus I/O refresh cycle of the Slave Termi-
nals are automatically calculated by the Sysmac Studio according to the input refresh cycle of the
NX Units in the Slave Terminals when the Slave Terminals are configured and set up.
*1. If multiple Slave Terminals are present on the same EtherCAT network, refer to
NX-series EtherCAT Coupler
Units User’s Manual (Cat. No. W519)
for the range of available Slave Terminals that operate at the same tim-
ing.
