Allocating Variables to the I/O Ports

Use Configurations and Setup - I/O Map on the Sysmac Studio to assign variables to the I/O ports of
the IO-Link Master Unit.
The following example uses port 1 (Photoelectric Sensor) and port 2 (Proximity Sensor) of an NX-type
IO-Link Master Unit.
Additional Information
You can use the IO-Link Master Simple Settings function to set the IO-Link Master Unit and
generate I/O ports in the I/O Map according to the process data structure of the IO-Link device.
For these I/O ports, the variables that are generated in the Create Device Variable facilitate
programming because they have data types and variable names set according to the process
data structure of the IO-Link device.
You can use the IO-Link Master Simple Settings function for an NJ/NX-series CPU Unit with
version 1.40 or later and Sysmac Studio version 1.29 or higher.
Refer to 8-2-4 IO-Link Master Simple Settings on page 8-15 for details on the IO-Link Master
Simple Settings.

Checking the Status of the IO-Link Master Unit

In this example, checking is performed for the following errors.
• Device Configuration Verification Error
• IO-Link Communications Error
• I/O Cable Short-circuit
• Error-level Device Event
