(For PNP) NXR-
CD166C-IL2 The Digital I/O Variable Hub has functionality to process input of digi-
tal signals from connected external devices as well as functionality to
process output of digital signals to connected external devices. The
Hub allows you to set each of pin 4 and pin 2 of the ports to input or
output. The Hub also communicates with the IO-Link Master Unit
through IO-Link.

Features
The NXR-series IO-Link I/O Hubs have the following features.
Features of Digital Input Hub

Expanding the Number of Digital Inputs of IO-Link Master Unit
In combination with an NXR-series IO-Link Master Unit for EtherNet/IP, the Digital Input Hub ena-
bles you to expand the number of inputs to up to 136 points per EtherNet/IP node.
*1
*1. You can use up to 136 points when you use the eight digital inputs for pin 2 of your IO-Link Master Unit. If
you do not use digital inputs for pin 2, you can use up to 128 points.

Detecting Errors That Occur between the Digital Input Hub and a Connect-
ed External Device
The Digital Input Hub detects short-circuit and disconnection that occur to the I/O cables between
the Digital Input Hub and a connected external device.
(Refer to
7-1-2 I/O Cable Disconnection Detection on page 7-3 and 7-1-3 I/O Cable Short-circuit
Detection on page 7-6.)
Features of Digital I/O Variable Hub

Expanding the Number of Digital I/O Points of IO-Link Master Unit
In combination with NXR-series IO-Link Master Unit for EtherNet/IP, the Digital I/O Variable Hub
can expand the number of inputs up to 136 points and the number of outputs up to 128 points per
EtherNet/IP node.
