6 Configuring and Programming the CP as a PROFINET IO Device

6.5Example of Configuration and Programming

The configured input/output modules must be accessed in the user program of the PROFINET IO device using FCs. The FCs provide the process data preprocessed in the user program of the PROFINET IO device on the interface to the PROFINET IO controller (PNIO_SEND) or fetch the data provided by the PROFINET IO controller for further processing in the user program of the PROFINET IO device (PNIO_RECV).

The following example shows the configuration in HW Config and excerpts of the user program of the CPU.

I addresses and O addresses configured on the PROFINET IO controller

The schematic shows the CP configured as a PROFINET IO device in the PROFINET IO system with three modules for process inputs and process outputs.
