Connected Device Verification

This section describes verification of the IO-Link device configuration in IO-Link Mode.

Overview

Connected device verification allows you to disable IO-Link communications with an IO-Link device
that was not intentionally connected by the user.
In IO-Link Mode, you can compare the configuration of the IO-Link devices that are actually connected
against the registered IO-Link device connection configuration.
Connected device verification is possible only for IO-Link devices.
The IO-Link device configuration settings information include the vendor ID, device ID, IO-Link revi-
sion, and serial number.

You can verify the vendor ID, device ID, serial number, and IO-Link revision of the connected IO-Link
device for each port using either of the following two patterns.
• Vendor ID + Device ID + IO-Link revision
• Vendor ID + Device ID + Serial number + IO-Link revision
If an inconsistency is detected during verification, IO-Link communications (both cyclic communica-
tions and message communications) for the port with the inconsistency will stop, and a device configu-
ration verification error will occur.
The overall operation of the IO-Link Master Unit will continue.
Connected devices can be verified for only IO-Link devices. If a non-IO-Link device is connected when
the connected device verification function is enabled and the communications mode is set to IO-Link
Mode, an IO-Link communications error will occur.
You do not necessarily have to make the IO-Link Device Configuration Settings for an IO-Link System.
These settings are used to verify the actual device configuration when IO-Link communications start.
These settings are not required unless you want to verify the configuration.

Verification is executed when IO-Link
communications are established.
If there is a verification error, IO-Link
communications will stop for the port
