Utilizing IOLM Features
78
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.
Although you can make configuration changes using the web page, PROFINET IO configuration
parameters overwrite the values on the
IO-Link Settings
page. See
IO-Link Port Settings (IO-Link Port
for PROFINET IO configuration procedures.
8.2.1
Uploading Data Storage to the IOLM
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
- If a port is set to On for this option, the IOLM saves the data storage
parameters (if the data storage is empty) from the IO-Link device to the IOLM.
•
When this option is enabled and another IO-Link device (different Vendor ID and Device ID),
the IO-Link Diagnostics page displays a
DS: Wrong Sensor
in the IOLink State field, and the IO-
Link port LED flashes 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 and the IO-Link device is connected to the
port.
•
The IO-Link device has the DS upload bit on; generally because you have changed the
configuration through Teach buttons or the web interface.
Note: Not all device parameters are sent to data storage. The IO-Link device manufacturer determines
what parameters are sent to data storage.
•
Data Storage Manual Ops: UPLOAD -
Selecting the UPLOAD button saves the data storage from
the IO-Link device to the IOLM. The contents of the data storage do 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.
8.2.2
Downloading Data Storage to the IO-Link Device
There are two methods to download Data Storage using the Configuration | IO-Link Device page:
•
Automatic Download Enable -
An automatic download occurs when the Automatic Download
Enable
option is set to On and one of these conditions exists:
•
The original IO-Link device is disconnected and an IO-Link device whose configuration data
differs from the stored configuration data.
•
The IO-Link device requests an upload and the Automatic Upload Enable option is set to Off.
Note: Do not enable both Automatic Upload and Download at the same time, the results are not
reliable
among IO-Link device manufacturers.
•
Data Storage Manual Ops: DOWNLOAD -
Selecting the DOWNLOAD button downloads the
data storage from that port to the IO-Link device.
If an IO-Link device with a different Vendor ID and Device ID is attached to the port and a manual
download is attempted, the IOLM issues a hardware fault.
