Features of the IO-Link Master Units
This section describes the features of IO-Link Master Units.
An IO-Link Master Unit is an NX Unit that has I/O processing functions for IO-Link communications with
IO-Link devices and I/O processing functions for digital I/O data (ON/OFF signals) with non-IO-Link
devices.
The NX-series IO-Link Master Unit has the following features.
NX-series IO-Link Master Units are NX Units. They can be connected to the following Units.
*1
• NX-series NX1P2 CPU Unit
• NX-series Communications Coupler Units
If you use both CPU Units and Communications Coupler Units, you can use the same NX Unit mount-
ing, wiring, and setup methods to reduce design costs.
The controller can read the following information as IO-Link Master Unit status.
• Signals and status of the IO-Link devices (examples for photoelectric sensor: unstable detection and
sensor errors)
• Disconnections, short-circuits, I/O power ON status, etc., between the IO-Link master and devices
With IO-Link devices that support digital inputs for pin 2,*1 the IO-Link Master Unit can simultaneously
perform both IO-Link communications and receive the digital inputs.
This enables rapid input during IO-Link communications.
*1. Digital inputs that use pin 2 of IO-Link Master Unit ports.
• You can connect a combination of IO-Link devices and non-IO-Link devices, such as general-pur-
pose sensors and actuators, to the same IO-Link Master Unit. This allows a single master to function
as an IO-Link communications terminal, a digital input terminal, and a digital output terminal.
• When you change from an existing system to an IO-Link System, there is no need to replace the
cables of existing general-purpose sensors or actuators.
