7 Programming FCs (Functions) and FBs for S7 Ethernet CPs
A-244
S7-CPs for Industrial Ethernet Configuring and Commissioning
Release 01/2007
C79000-G8976-C182-07
7.8.2 FC12 PNIO_RECV
The PNIO_RECV FC is used to accept data in the PROFINET IO controller or
PROFINET IO device CP modes.
 Operation as PROFINET IO controller
The block accepts the process data from PROFINET IO devices (inputs of the
controller) and transfers the IO provider status (IOPS) from the PROFINET IO
devices to the specified input areas.
 Operation as PROFINET IO device
The block receives the data transferred by the PROFINET IO controller
(configured O addresses) as well as the IO Provider Status (IOPS) of the
PROFINET IO controller and writes them to the data areas on the CPU of the
PROFINET IO device reserved for the process outputs.
