Types of IO-Link Master Units

The NX-series IO-Link Master Unit is an NX Unit that has I/O processing functions for IO-Link commu-
nications with IO-Link devices and I/O processing functions for digital I/O data (ON/OFF signals) with
non-IO_Link devices. For an IO-Link Master Unit, processing functions can be assigned for each port to
combine different types of I/O processing functions.
Also, with IO-Link devices that support digital inputs for pin 2,
ously perform both IO-Link communications and receive digital inputs.
*1. Digital inputs that use pin 2 of IO-Link Master Unit ports.
The following types of I/O data are available.

6-1-2 Connection Configuration with the Communications Coupler Unit
or CPU Unit and IO-Link Devices
An NX-series IO-Link Master Unit connects to IO-Link devices. As an NX Unit, an NX-series IO-Link
Master Unit can be connected to any of the following.
Connected to an NX1P2 CPU Unit
You can connect an IO-Link Master Unit directly to the CPU Rack.
