The process data size setting for each IO-Link channel can be read and written. The
value shows the mapped process data size for each IO-Link channel in Words (0 -
16). The sum of all IO-Link channel's data size + message transmission area must
not exceed the maximum available Word area, which is determined by the number of
occupied stations and extended cyclic setting. See also CC-Link Profile Number.
The order in which IO-Link process and parameter data is mapped can be set
with bit 7 (high byte/ low byte).

The event data (Event qualifier and event code) of a pending event indicated
Event data by the IO-Link channel event flag can be read. After reading the event data the IO-
Link port event flag changes to 0.
IO-Link device validation. The validation type is defined as follows:
0x00 = validation deactivated
0x01 = validation of IO-Link Vendor ID and IO-Link Device ID
Validation
0x02 = validation of IO-Link Vendor ID, IO-Link Device ID and serial number
data
Depending on the configuration of the IO-Link device validation, the connected
device's information is verified and the result indicated by the port LED 'IO-link' and
'IO-Link Channel established' flag.
