5.8 PROFIBUS DP interface (X2, X3)
Connectable devices
The PROFIBUS DP interface can be used to set up a PROFIBUS master system, or to
connect PROFIBUS I/O devices.
You can connect redundant I/O to the PROFIBUS DP interface.
You can connect any standard-compliant DP slaves to the PROFIBUS DP interface.
Here, the CPU represents the DP master, and is connected to the passive slave stations or,
in stand-alone mode, to other DP masters via the PROFIBUS DP fieldbus.
Various compatible devices take the 24 V supply from the interface. This voltage provided at
the PROFIBUS DP interface is non-isolated.
Connectors
Always use bus connectors for PROFIBUS DP and PROFIBUS cables to connect devices to
the PROFIBUS DP interface (
refer to the Installation Manual ).
Redundant mode
In redundant mode, the PROFIBUS DP interfaces have the same parameters.
5.9 PROFINET interface (X5)
Assigning an IP address
You have the following options of assigning an IP address to the Ethernet interface:
● By editing the CPU properties in HW Config. Download the modified configuration to the
CPU.
You can also set up the IP address parameters and the station name (NameOfStation, NoS)
locally without having to modify the configuration data.
● Using the "PLC -> Edit Ethernet Node" command in SIMATIC Manager.
These local settings are always possible, regardless of whether the PROFINET IO interface
is set up as intelligent device or IO controller in the parameters.
Devices which can be connected via PROFINET (PN)
● Programming device/PC with Ethernet adapter and TCP protocol
● Active network components, e.g. Scalance X200
● S7-300/S7-400, e.g. CPU 417-5H PN/DP
● PROFINET IO devices, e.g. IM 153-4 PN in an ET 200M
