• The High-speed Analog Input Units in the Slave Terminal read input changed times at a fixed in-
terval based on Sync0. (Refer to (a) in the figure below.)

• The High-speed Analog Input Units read input values at the timing of I/O refreshing, which is dif-
ferent from the timing of reading input changed times.
• The EtherCAT Coupler Unit reads the input changed times and input values at I/O refreshing im-
mediately after the input changed times are read. (Refer to (b) in the figure below.)
• The interval of I/O refreshing varies depending on the operational conditions of the EtherCAT
Coupler Unit or the EtherCAT master. (Refer to (c) in the figure below.) Input changed times are
read at a fixed interval. (Refer to (d) and (e) in the figure below.)
• Sync0, the timing of reading input changed times, and the maximum NX bus I/O refresh cycle for
multiple Slave Terminals are automatically calculated by the Sysmac Studio according to the in-
put refresh cycles of the NX Units in the Slave Terminals when the Slave Terminals are config-
ured 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 timing.
