Parameter server
The following options are available for the parameter server:
Option
Description
Switched on
Data storage function is active. Parameter and identifica-
tion data for the IO-Link device is saved retentively.
Switched off
Data storage function is deactivated. The saved data are
retained.
Deleted
Data storage function is deactivated. The saved data is
deleted.
Enable of block
upload
Enable or block the parameter data upload into the IO-Link
Master port data storage.
• Enable upload: The IO-Link Master starts to upload the
parameter data as soon as an IO-Link device requests
an upload (upload flag set) or if there is no data stored
in the master port, e.g., after the data has been deleted
or before the first data upload
• Block upload: If the upload is blocked, the data is not
uploaded. If an IO-Link device sends an upload request,
a download starts if there are different parameter sets
since an upload cannot take place. The download must
be enabled.
Enable or block
download
Enable or block the parameter data download to the IO-
Link device.
• Enable download: As soon as the saved parameter
data in the parameter server of the port differs from a
connected IO-Link device and there is no upload request
from the IO-Link device, a download is performed.
• Block download: If the download is blocked, the parame-
ter data is uploaded if it is activated. The upload flag for
the IO-Link device does not need to be set in this case.
The upload must be enabled.
Block upload and
download
If both upload and download are blocked, the parameter
data is not exchanged. However, the IO-Link device still
communicates with the IO-Link port.

NOTE!
After the parameter data upload, the vendor ID and de-
vice ID are retained until the data sets of the connected
IO-Link device are deleted.
A validation takes place when the connected IO-Link de-
vice starts up. This means that only one IO-Link device of
the same type can be used for data storage. In order to
use an IO-Link device of a different type, you must delete
the content of the parameter server.
