11.3.2.5 PARAM_SERV_MODI
The PARAM_SERV_MODI data field contains the configuration settings for the
mode of the IO-Link parameter server. This is active by default.
The following table provides an overview of the data structure.

Disable Upload: Prevents parameter upload
The upload request of the IO-Link device is suppressed by
the I/O module.

Disable Download: Prevents parameter download
The download request of the control is not sent to the IO-
Link device by the I/O module.
Application parameter upload:
The IOL-D parameters are uploaded to the parameter server of the IO-Link master
if the device parameters have been changed.
This occurs either "remotely" via the bus or "locally" on the device. In this case,
an internal flag is set in the device that is queried by the master when starting
next.
Application parameter download:
When uploading to the IO-Link device, the master checks the identity of the
device (DeviceID, VendorID, SerialNumber).
When successful, the parameter server synchronizes the parameters:
•
For devices without ISDU support, parameters are always downloaded.
•
For devices with ISDU support, parameters are only downloaded if the
checksums do not equal the parameter sets.
11.3.2.6 IOLD_FEATURE
The IOLD_FEATURE data field is reserved for various configuration bits. Only
one is used currently for activation/deactivation of device diagnosis. By default,
transmission of diagnostic message via the internal bus to the control is enabled.
The following table provides an overview of the data field.
