Allocatable I/O Data
Eight I/O entry mappings are assigned to the I/O allocation settings for the High-speed Analog Input
Units. The I/O entries for the High-speed Analog Input Units are assigned to the I/O entry mappings.
An I/O entry means the I/O data described in this section. An I/O entry mapping means a collection of
I/O entries.
For the High-speed Analog Input Units, the allocation of I/O entry mappings is fixed.
When you click the Update I/O Entry Button in the Edit I/O Allocation Settings Window on the Sysmac
Studio, required I/O entries are automatically assigned for the High-speed Analog Input Units, based
on the following settings:
• Ch£ Enable/Disable
• Ch£ Number of Samplings Setting
When you assign the I/O allocation information of the NX Unit or EtherCAT Slave Terminal to an
NJ/NX-series CPU Unit or NY-series Industrial PC, use the I/O ports for the allocated I/O data.
This section shows I/O data that can be allocated to the High-speed Analog Input Units, and an exam-
ple of I/O entry allocation.
