Utilizing IO-Link Master Features

This chapter discusses using the following features:
Data Storage (automatic and manual) to upload or download IO-Link v1.1 device parameters

Device Validation (identical or compatible) to dedicate a port or ports to specific IO-Link devices

Data Validation (strict or loose) to verify data integrity

Menu Bar Hover Shows Submenu, which provides an option to navigate the submenu structure

quickly.
Note: You must configure data storage, device validation, data validation in PROFINET IO using Step 7.
You can use data storage on the web page for temporary data storage related tasks.

Data Storage

Data storage is typically supported by IO-Link v1.1 devices.
parameters from an IO-Link device to the IO-Link Master and/or download parameters from the IO-Link
Master to the IO-Link device. This feature can be used to:
 Quickly and easily replace a defective IO-Link device
 Configure multiple IO-Link devices with the same parameters as fast as it takes to connect and
disconnect the IO-Link device
To determine whether an IO-Link (v1.1) device supports data storage, you can check one of the
following:
 IO-Link Diagnostics page - check the Data Storage Capable field to see if it displays Yes.
 IO-Link Configuration page - check to see if UPLOAD and DOWNLOAD buttons display under
the Data Storage Manual Ops group. If only a Clear button displays, the device on the port does
not support data storage.

10.1.1 Uploading Data Storage to the IO-Link Master

The IO-Link device manufacturer determines which parameters are saved for data storage. Remember,
the IOL-Link device should be configured before enabling data storage unless you are using data storage
to back up the default device configuration.
There are two methods to upload Data Storage using the Configuration | IO-Link page:
Automatic Enable Upload

storage (if the data storage is empty) from the IO-Link device to that port. Some IO-Link devices
update the data storage contents if you use the Teach buttons on the IO-Link device, but that is
determined by the IO- Link device manufacturer.
When this option is enabled and another IO-Link device (different Vendor ID and Device ID), the IO-Link
Diagnostics page displays a
red, indicating a hardware fault.
Automatic upload occurs when the Automatic Upload Enable option is set to On and one of these
conditions exists:
 There is no upload data stored on the gateway.
 The IO-Link device executes a requests_ at upload function (generally because you have
changed the configuration via Teach buttons).
You should not enable Automatic Upload until after you have configured the IO-Link device attached to
the port unless you want to capture the default settings.
Note: Do not enable both Automatic Upload and Download at the same time, the results are not reliable among
IO-Link device manufacturers.

from the IO-Link device to that port. The content of the data storage does not change unless it is
uploaded again or cleared. Another IO-Link device with a different Vendor ID and Device ID can
be attached to the port without causing a hardware fault.
