Final Check of Task
Period/Sampling
Period
Check whether or not you need to set a
task period again, since the task period
may need to be changed depending on the
size of the user program.
To change the task period, you need to set
a task period again. After completion of the
setting, perform the final check of the sam-
pling period on the Sampling Settings and
Digital Filter Settings Tab Page. If you
change the task period or a Unit operation
setting on the Digital Filter Settings Tab
Page, the change is immediately reflected
on the sampling period value.

Settings
*1.
To connect to the CPU Unit, check this on the CPU and Expansion Racks Tab Page. To connect to the Com-
munications Coupler Unit, check this on the Edit Slave Terminal Configuration Tab Page.
*2.
Check this on the Multi-view Explorer.
Precautions for Correct Use
• For the High-speed Analog Input Units, it takes time until the NX Unit I/O Data Active Status
changes to TRUE when power is turned ON or the Unit is restarted. When you write the pro-
gram, make sure that the Unit always checks if the NX Unit I/O Data Active Status has
changed to TRUE before it starts operation.
Refer to the software user's manual for the connected CPU Unit or the user’s manual for the
connected EtherCAT Coupler Unit for information on the NX Unit I/O Data Active Status.
• When you use an NX-series High-speed Analog Input Unit in the CPU Rack or Slave Termi-
nal, the primary periodic task or the priority-5 periodic task should be assigned. If any other
periodic task is assigned, the Unit does not perform sampling correctly.
When any other periodic task is assigned, the High-speed Analog Input Units do not perform
sampling throughout the task period. They perform sampling only during a part of the task pe-
riod. Note that the Sysmac Studio does not display a correct sampling period on the Edit I/O
Allocation Settings Window and the Sampling Settings and Digital Filter Settings Tab Page.
