Parameter "Port x > Length of the input process image"
This parameter is used to set the size of a port segment for the process input data
on the internal bus in the unit "Byte". With a segment length of 0, no process data
from the IO-Link device (when connected) appears. The maximum width of a
segment is 15 bytes.
The segments of all ports are one right after the other. The settings are saved in
retentive memory.
Enable fragmentation when the segment width is too small!
When the process data width of an attached IO-Link device is greater than the
segment width available, enable fragmentation for the port concerned.
If fragmentation is enabled, the process data is transmitted cyclically in a
fragmented manner per port.
If you do not enable fragmentation, only the available segment width is used and
all other data is lost.
If fragmentation is ON, the input process data must be defragmented by a suitable
function block in the PLC.

This parameter is used to set the size of a port segment for the process output data
on the internal bus in the unit "Byte". The settings are made in units of 1 byte.
With a segment length of 0, no process data from the IO-Link device (when
connected) appears. The maximum width of a segment is 15 bytes.
The segments of all ports are one right after the other. The settings are saved in
retentive memory.

When the process data width of an attached IO-Link device is greater than the

If you do not enable fragmentation, only the available segment width is used and

If fragmentation is ON, the output process data must be fragmented by a suitable
