C79000-G8976-C198-04
1 Properties / Services
Application
The CP 3431 Lean communications processor is designed for operation in a
SIMATIC S7-300 programmable logic controller. It allows attachment of the
S7300 to Industrial Ethernet and supports PROFINET IO.
A 2-port switch with autocrossing, autonegotiation and autosensing was integrated
in the CP for simple integration in a line or for attaching a further Ethernet device.
Services
The CP supports the following communication services:
S PROFINET IO device
Integration of the SIMATIC S7300 programmable controller over the CP as
intelligent PROFINET IO device.
S S7 communication and PG/OP communication
PG functions (including routing)
Operator control and monitoring functions (HMI)
Server for data exchange on S7 connections configured at one end only
without communication blocks on the S7-300 / C7-300 station
S S5 compatible communication with
SEND/RECEIVE interface over ISO-on-TCP, TCP and UDP connections
Multicast over UDP connection
The multicast mode is made possible by selecting a suitable IP address
when configuring connections.
FETCH/WRITE services (server; corresponding to S5 protocol) via
ISO-on-TCP connections and TCP connections;
The addressing mode can be configured for FETCH/WRITE access as the
S7 or S5 addressing mode.
LOCK/UNLOCK with FETCH/WRITE services;

S Time-of-day synchronization over Industrial Ethernet using the following
configurable modes:
SIMATIC mode
The CP receives MMS time frames and synchronizes its local time and the
time of the CPU (accuracy approx. +/ 1 second);
or
NTP mode (NTP: Network Time Protocol)
The CP sends time-of-day queries at regular intervals to an NTP server and
synchronizes its local time of day and the time of the CPU (accuracy approx.
+/ 1 second).
S Time of day for the diagnostic buffer
If a time master exists (using the NTP or SIMATIC mode), the time for the
CP-internal diagnostic buffer is synchronized over the LAN (accuracy approx.
+/ 10 ms)
S Addressing using a factory-set MAC address
The CP can be reached over the default MAC address to allow an IP address to
be assigned.
S SNMP Agent
The CP supports data queries over SNMP in version V1 (Simple Network
Management Protocol) according to the MIB II and LLDP MIB standard.
You will find more information on MIB in the manual “Commissioning PC
Stations” on the SIMATIC NET Manual Collection or at the following
SIMATIC NET Internet page:
http://support.automation.siemens.com/WW/view/en/15177711
S IP configuration
You can configure how and with which method the CP is assigned the IP
address, the subnet mask and the address of a default router.
It is also possible, as an alternative, to assign the connection configuration to
the CP using STEP 7 or using a block interface in the user program (FB55:
IP_CONFIG) (see /Part A/).
S Web diagnostics
With the aid of Web diagnostics, you can read out the diagnostic data from a
station connected over the CP to a PG/PC with an Internet browser.

Configuration
It is possible to download the configuration data to the CP over MPI or
LAN/Industrial Ethernet. You require STEP 7 with NCM S7 for Industrial Ethernet
(NCM IE) with the following version:
Table 1-1
Version STEP 7 / NCM IE Functions of the CP
V5.2 or higher The range of functions of the CP 3431 Lean (CX00) can be
configured.
V5.4 or higher Requirement for configuring the full functionality of the
CP 3431 Lean (CX10 with firmware V1.0) including PROFINET
IO.
V5.4 Service Pack 2 *) Requirement for configuring the full functionality of the
CP 3431 Lean (CX10 with firmware V2.0) including Web
diagnostics.
*) To use the CP with V5.4 Service Pack 1, you will need to install Hotfix 2, the corresponding hardware
update and a block setup. You will find more information at the following Internet page:
http://www4.ad.siemens.de/WW/news/en/24463868
Programming Using Blocks
For some communications services, there are pre-programmed blocks (FCs/FBs)
available as the interface in your STEP 7 user program.
You will find a detailed description of these blocks in the NCM S7 for Ethernet
manuals.
Notice
We recommend that you always use the latest block versions for all module types.
You will find information on the latest block version and links to download the
current blocks in our Customer Support area on the Internet:
http://www4.ad.siemens.de/WW/news/en/8797900
If you are using older block types, this recommendation only applies if you also
have the latest firmware version.
You will find further information and Internet addresses in the Preface of the
General Part of this manual.

Release 03/2007
C79000-G8976-C198-04
3 Installation and Commissioning
3.1 Procedure / Steps
Step Explanation / Meaning
1. Install the CP on the S7 standard rail.
2. Establish the connection via the enclosed bus
connector to the backplane bus.
Slots 4 to 11 are permitted for the CP in racks 0 to 3
(connected by IM 360/361).
Proceed as in the sections dealing with setup and
wiring, described in detail in /1/.
Note
The CP cannot be used in an extension rack that is connected via the IM 365! Reason: The required
communication bus is not connected to the extension rack via the IM 365.
3. Connect the CP to the power supply. Follow the steps as described in detail in /1/ when
wiring between the power supply and the CPU.
Notes
S The CPU, CP and IM (if one exists) must be connected to the same power supply.
S Only wire up the S7-300 / C7-300 with the power switched off!
4. Attach the CP to Industrial Ethernet.
5. The remaining steps in commissioning involve
downloading the configuration data.
To download the configuration, you can connect
the PG as follows:
S via MPI
S via Industrial Ethernet
For further details, refer to the general Part A of
this manual:
addressing the first time (IP address
assignment / node initialization);
downloading the defined configuration
The PG/PC requires a LAN attachment, for
example via a CP 1613 or CP 1411 and must have
the necessary software (for example the S7-1613
package or SOFTNET IE). The TCP/IP protocol
must be installed. The protocol used must then be
applied to the S7ONLINE access point.
6. User diagnostics for commissioning and to
analyze problems.
The following options are available:
S The LED displays on the CP
S Hardware diagnostics and troubleshooting with
STEP 7
S Communication diagnostics with STEP 7 / NCM
Diagnostics
S Standard information using HW Config
S Web diagnostics
S If applicable, evaluation of the alarm block
FB54 in the user program

S Free UDP connections are supported by the

Max. data length for blocks AG_SEND (V4.0 and
higher) and AG_RECV (V4.0 and higher)
AG_SEND and AG_RECV allow the transfer of
data fields of between 1 and 240 bytes.
S 1 to 8192 bytes for ISO-on-TCP, TCP;
S 1 to 2048 bytes for UDP
Restrictions for UDP
S Transfer is not confirmed The transmission of UDP frames is unconfirmed, in
other words the loss of messages is not detected
or displayed by the send blocks (AG_SEND).
S Data field length The maximum length of the data fields is 2048
bytes.
S No reception of UDP broadcast To avoid communication overload resulting from a
high broadcast load, the CP does not permit
reception of UDP broadcast.
Execution Times of the FCs AG_SEND / AG_RECV
To calculate the CPU cycle times (OB1) with SEND/RECEIVE connections, the
execution time for the FCs (FC AG_SEND, FC AG_RECV) required for processing
on the S7300 / C7300 CPU is the decisive factor.

Execution times of the FCs PNIO_SEND / PNIO_RECV

execution time of the function blocks required on the S7-300 CPU (PNIO_SEND,
PNIO_RECV).

6 Configuring and Programming the CP as a
PROFINET IO Device
“Intelligent” PROFINET IO Device
A CP 3431 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
