6 Configuring and Programming the CP as a
PROFINET IO Device
“Intelligent” PROFINET IO Device
A CP 343−1 Lean can be configured so that the SIMATIC 300 station can be
addressed as a PROFINET IO device. Due to the programmability of SIMATIC 300
stations, they are also known as “intelligent” PROFINET IO devices because:
Process data can be processed before it is forwarded to the PROFINET IO
controller or after it has been received from it and output to the process I/O.
In the following sections, the name “PROFINET IO device” also refers to the CP
located in the S7 station and configured as a PROFINET IO device.
6.1 Overview of the Preparatory Steps
The following steps are necessary to operate the SIMATIC 300 station with the
CP as a PROFINET IO device:
Write the user program for the PROFINET IO
device SIMATIC S7 and download it to the
SIMATIC S7 CPU. See Section 6.4
Configure the CP as PROFINET IO device for
data exchange over PROFINET IO. See Section
6.3
Communication diagnostics (for example
if problems occur during communication)
Commission and test the PROFINET
IO controller and PROFINET IO
device
