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.
Download and Upload:
Enables the IO-Link parameter data download and upload function.
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. The parameter data read are permanently
stored on the master.
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.
For each new connection to an IO-Link device, 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.
The IO-Link device can be replaced in this mode.
