Transfer the process inputs (DB10) to the I addresses with PNIO_SEND
For the configured I addresses, you will need to make data areas available on the
PROFINET IO device, for example in a DB (in this example in a DB10) that
contains not only the process data but also the data areas for the IOCS status
information.
