6.4 Configuration of the LioN-P
PROFINET I/O modules in STEP 7
6 Starting operation
If parameter data of a device were stored previously,
these data remain stored without any changes.
Download only (master to device)
Enables the parameter data download function to the
IO-Link device on the master.
Parameter data can only be uploaded to an IO-Link
device if they exist on the parameter server and are
usable for the device. When an IOLink device is
connected, the master compares the stored parameter
data with the device data. If the function is not locked
on the device ("Parameter storage" locked), the master
downloads the stored data to the device in case of
differences.
IO-Link device data can be loaded using the "Upload
only" mode. If the master does not have a device
parameter set stored, the mode must be compared with
"Disabled".
Replacement of the IO-Link device is possible in this
mode.
Upload only (device to master)
Enables the parameter data upload function to the IO-
Link master from the device.
An upload is performed when an IO-Link device is
connected and the master does not have any valid data.
This is the case if "Disabled and Cleared" mode was
configured previously and/or in case of "Disabled" in as-
delivered condition.
If parameter data are changed on the device during
runtime, the device data stored on the master can
be overwritten using the ParamDownloadStore (Index
0x0002, Subindex 0x00, Value 0x05 command. This
command sets the DS_UPLOAD_REQ flag on the
device, and thus executes an upload.
The IO-Link master can be replaced in this mode.
