Note
(for DP interface in slave mode only)
When you disable the Commissioning / Debug mode / Routing check box in the DP interface
properties dialog in STEP 7, all user-specific transmission rate settings will be ignored, and
the transmission rate of the master is automatically set instead. This disables the routing
function at this interface.
Devices capable of PROFIBUS DP communication
• PG/PC
• OP/TP
• DP slaves
• DP master
• Actuators/Sensors
• S7-300/S7-400 with PROFIBUS DP interface

3.1.3 PROFINET (PN)
Availability
CPUs with a "PN" name suffix are equipped with a PROFINET interface.
Connecting to Industrial Ethernet
You can use the integrated PROFINET interface of the CPU to establish a connection to
Industrial Ethernet.
The integrated PROFINET interface of the CPU can be configured via MPI or PROFINET.
Devices capable of PROFINET (PN) communication
• PROFINET IO devices (for example, interface module IM 151-3 PN in an ET 200S)
• S7-300 / S7-400 with PROFINET interface (for example, CPU 317-2 PN/DP or CP 343-1)
• Active network components (a switch, for example)
• PG/PC with network card
