S7-CPs for Industrial Ethernet Configuring and Commissioning

7.8.1 FC11 PNIO_SEND
The PNIO_SEND FC is used to transfer data in the PROFINET IO controller or
PROFINET IO device modes of the CP.
Operation as PROFINET IO controller
The block transfers the process data (outputs) of a specified output area to the
CP to be forwarded to PROFINET IO devices and as status display returns the
IO consumer status (IOCS) of the outputs of the PROFINET IO devices.
Operation as PROFINET IO device
The block reads the preprocessed process inputs of the CPU on the
PROFINET IO device and transfers them to the PROFINET IO controller
(configured I addresses); the block also returns the IO Consumer Status (IOCS)
of the PROFINET IO controller as a status display.
The preprocessed process data is available in a DB or bit memory area.
