I/O Data Specifications
This section describes the data items that you can allocate to I/O, the data configurations, and the axis
settings.
You can allocate the following 15 data items to the I/O for an Incremental Encoder Input Unit.
The data items are described in the following sections.
Additional Information
• If you use an EtherCAT Coupler Unit, you can use the Read NX Unit Object instruction or the
Write NX Unit Object instruction to access data that is not assigned as I/O. Refer to the
NJ/NX-series Instructions Reference Manual
(Cat. No. W502) for details on the Read NX
Unit Object instruction or the Write NX Unit Object instruction.
For the index numbers, refer to
A-2-2 Incremental Encoder Input Units
• If you use an EtherNet/IP Coupler Unit, you cannot access data that is not assigned to I/O.
The data items that you can allocate to I/O for a One-input Unit are listed in the following table.
