Checking for Errors and Trouble-
shooting with the Device Events
The IO-Link I/O Hub registers an error that occurs to itself as a device event.
Occurrence of a device event is notified to the IO-Link Master Unit and then reflected in the following
I/O data of the IO-Link Master Unit.
• I/O Port Error Status
Checking the I/O data enables you to know occurrence of a device event.
Refer to the
NXR-series IO-Link Master Unit for EtherNet/IP User’s Manual (Cat. No. W619)
for de-
tails on the I/O Port Error Status of the IO-Link Master Unit.
The device events of the IO-Link I/O Hub are described below.
8-4-1
Device Events
This function registers an error that occurs to the IO-Link I/O Hub as a device event and notifies it to
the IO-Link Master Unit. Each device event can be registered only once. The same event is not regis-
tered more than once. Refer to
8-4-3 List of Device Events and Troubleshooting
tails on the device events registered.
The following describes how to read and clear device events.
8-4-2
Reading and Clearing Device Events
This section describes how to read and clear device events.
Reading Device Events
There are two ways to read device events as below.
• Using CX-ConfiguratorFDT
• Using message communications from the Controller to the IO-Link device
Precautions for Correct Use
• Device events are registered in a volatile memory and therefore cleared from the IO-Link I/O
Hub once the Unit/input power supply is turned OFF.
• Device events are also cleared from CX-ConfiguratorFDT if you turn OFF the Unit/input pow-
er supply and then read the device with CX-ConfiguratorFDT.
Using CX-ConfiguratorFDT
This section describes how to read device events with CX-ConfiguratorFDT. Refer to
Setting IO-
Link Devices with the CX-ConfiguratorFDT
in the
NXR-series IO-Link Master Unit for EtherNet/IP
User’s Manual (Cat. No. W619)
for how to create a network configuration and how to go online.
1
Create a network configuration and then register the IO-Link I/O Hub.
2
Right-click the device DTM and select
Go online
