6 Configuring and Programming the CP as a PROFINET IO Device
Transfer the O addresses to the process outputs (DB11) with PNIO_RECV
For the configured O addresses, you will need to make data areas available on the
PROFINET IO device, for example in a DB (in this example in a DB11) that
contains not only the process data but also the data areas for the IOPS status
information.

Explanation
//PNIO_RECV block call
//(read outputs from IO controller)
//Module address from hardware configuration
//No. of log. O addresses to transfer in bytes
//Per receive data byte one status bit in DB11
//Address for return parameter NDR
//Address for return parameter ERROR
//Address for return parameter STATUS
//Address for return parameter CHECK_IOPS
//Received data in DB11 (7 bytes)
//Diagnostic information
