Error Notification Methods

This section shows an example of system configuration where an NXR-series IO-Link Master Unit for
EtherNet/IP is connected to an IO-Link I/O Hub and describes the methods of error notification. The
IO-Link I/O Hub notifies an error to the IO-Link Master Unit by the following methods. Refer to 

8-2 Checking for Errors

 on page 8-4 for how to check the notified error.

put data

Input data of the IO-
Link I/O Hub. The data
contain I/O Hub status
information as well as
input information from
connected external de-
vices.

When an error occurs, the Hub cyclically sends the following data of the
process input data through IO-Link communications to the IO-Link Mas-
ter Unit.

The sent statuses are stored in the following I/O data of the IO-Link
Master Unit.

•

IO-Link input data
The IO-Link Master Unit sends the data through network communica-
tions to the Controller.
In this example, the IO-Link Master Unit cyclically sends the data to
the Controller through tag data link of EtherNet/IP communications.
