Properties / services 1
1.1 Application
The CP 343- Lean communications processor is intended for operation in a SIMATIC S7-300
or SIMATIC C7 automation system. It allows the connection of the S7-300 to Industrial
Ethernet and supports PROFINET IO.
To integrate the CP in a linear bus or a ring, to connect a further Ethernet device or to use
PROFINET media redundancy, a 2-port ERTEC real-time switch with autocrossing,
autonegotiation and autosensing was integrated.
Functional enhancements of the CX10 from firmware version V2.6 to V3.0 - can be used with STEP 7
V5.5
The following new functions can be used with the module with firmware version 3.0:
● "Shared device" function with PROFINET IO
● Use of PROFIenergy functionality
This requires the following PROFIenergy program blocks for the CP 343-1 in the
"SIMATIC_NET_CP" library with the STEP 7 version listed above:
– PE_Start_CP, PE_CMD_CP, PE_I_DEV_CP and the program block DS3_WRITE_CP
for the use of power modules of the ET 200S for PROFIenergy.
– The supplementary program blocks FC0 to FC8 for the PROFIenergy response data
can be found in the Standard Library.
You will find the documentation of the program blocks in the online help and in the
manual for the program blocks, see References, /10/ (Page 62).

or
– NTP mode (NTP: Network Time Protocol)
The CP sends timeofday queries at regular intervals to an NTP server and
synchronizes its local time of day. The forwarding of the time-of-day to the CPU is
optional.
Accuracy approx. +/- 1 second
● Addressing using a factoryset MAC address
The CP can be reached via the default MAC address to allow an IP address to be
assigned.
● SNMP agent
The CP supports data queries over SNMP in version V1 (Simple Network Management
Protocol). It delivers the content of certain MIB objects according to the MIB II standard,
LLDP MIB, Automation System MIB and MRP Monitoring MIB.
● Module access protection
To protect the module from accidental or unauthorized access, protection can be
configured at various levels.
● IP configuration
For the PROFINET interface, you can configure how and with which method the CP is
assigned the IP address, the subnet mask and the address of a gateway.
As an alternative to STEP 7, you have the option of assigning the connection
configuration via a block interface in the user program (FB55: IP_CONFIG).
● Web diagnostics
With the aid of Web diagnostics, you can read out the diagnostics data from a station
connected via the CP to a PG/PC with a Web browser.
This makes it possible to read the diagnostics buffers of the intelligent modules in the
rack.
Using the integrated update center of the diagnostics pages, you can download new
firmware versions and diagnostics buffer message texts.
If you do not require the functions, you can disable it in the STEP 7 configuration and
disable port 80.
● Connection diagnostics with the AG_CNTEX program block
With the AG_CNTEX program block, you can diagnose connections.
– When necessary, you can activate or deactivate connections or initiate
reestablishment of a connection.
– You can check the reachability of the connection partners using the ping function.
– You can find out which connection types are set up for the SEND / RECEIVE
interface.

Ensuring ventilation
During installation, make sure that the upper and lower ventilation slits of the module are
not obstructed and good ventilation is possible.
Note
No installation in an expansion rack
The CP cannot be operated in an expansion rack that is connected via the IM 365.
Reason: The required communication bus is not connected to the expansion rack via the
IM 365.
2. Establish the connection via the enclosed bus connector to the backplane bus.
3. Connect the CP to the power supply.
Follow the steps as described in detail in /12/ (Page 62) when wiring between the power

Only wire up the S7300 / C7300 with the power switched off!
CP 343-1 Lean
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 S71613 package or SOFTNET IE). The
TCP/IP protocol must be installed. The protocol used must then be applied to the S7ONLINE
access point.
Diagnostics
Use the diagnostic functions during commissioning and to analyze problems. The following
options are available:
● The LED displays on the CP
● Hardware diagnostics and troubleshooting with STEP 7
● Communication diagnostics with STEP 7 / NCM Diagnostics
● Static information using HW Config
● Web diagnostics
● If applicable, evaluation of the alarm block FB 54 in the user program
● Queries via SNMP
Note
Autocrossing mechanism - effects on the connectors
For small local area networks or for attaching several Ethernet devices, a 2port switch
has been integrated on the PROFINET interface of the CP.
With the autocrossing mechanism integrated in the switch, it is possible to use a standard
cable to connect the PG/PC. A crossover cable is not necessary.
Please note the following points:
Manual configuration
If a port is set to manual configuration and autonegotiation is disabled, the
autocrossing mechanism is also disabled for this port. Which cable you need to use
depends on the partner device (network component or end device).
In the factory, the ports are set for automatic configuration.
For more information, refer to section Network settings (Page 38)
Connecting switches
If you connect further switches, make sure that no ring is formed in the network.

NOTICE
Project engineering
To set up the CP for communication services, read the information on configuring in the

see References /1/ (Page 60).
CP 343-1 Lean
Note
In normal situations, the basic setting ensures troublefree communication. You should only
change this in exceptional situations.
If you create a manual configuration for the CP, the automatic negotiation of the network
settings (autonegotiation) is no longer effective. If, on the other hand, the communication
partner works with autonegotiation, no communication will be established.
Only use manual configuration when the communication partner works with the same
manually set configuration.
Autocrossing mechanism
The automatic setting also includes an "autocrossing" mechanism. With autocrossing, you
can connect network components and end devices using either crossover or straight-through
cables.
STEP 7 special diagnostics and Web diagnostics display the network setting
Diagnostics of the port settings for the CP described here is possible using the entries in the
diagnostics buffer using Web diagnostics, SNMP, STEP 7 diagnostics, and the LED
displays.
You will find information on the currently used network settings in STEP 7 as follows:
CP 343-1 Lean

Notes on configuration and operation
6.3 Network settings
● In STEP 7 special diagnostics under the diagnostics object "Industrial Ethernet" in the
"Network Connection" group box
● in STEP 7 with the menu command "PLC > Module Information"
● In Web diagnostics
Further notes:
● Autocrossover
If you disable the "Automatic setting" option, autocrossing is disabled; which cable you
then use depends on the integration of the CP (network component or end device).
● 10/100 Mbps network components without "autonegotiation"
If you use 10/100 Mbps network components that do not support "Autonegotiation", it is
possible that you will have to set the mode manually in the CP configuration in STEP 7.
As default, the CP is configured for automatic detection.
● Forcing a specific network setting instead of "Autonegotiation"
If your application requires a fixed network setting instead of "Autonegotiation", both
partner devices must have the same setting.
● No reaction to Autonegotiation query with manual configuration
Remember that if you configure the CP manually, it will not react to an autonegotiation
query! As a result, a connected partner will not be able to make the required network
setting and communication will not be established.
Example:
If the CP is set to "100 Mbps full duplex", a CP connected as partner will set itself to "100
Mbps half duplex". Reason: Due to the fixed setting, no autonegotiation response is
possible; the connected partner recognizes the 100 Mbps with autosensing but
nevertheless remains in half duplex.
● Recommendation: Change "individual network settings" only over MPI
If you modify the LAN settings in the properties dialog of the CP in the “Port Parameters"
tab, these changes will be adopted by the CP and activated when the configuration data
is downloaded to the CP. In some situations, the device may then no longer be
obtainable over Ethernet.
We therefore recommend that you download configuration data to the S7 station over an
MPI connection if you change this setting.
If you download the configuration data over the LAN interface then, depending on the
selected setting, it is possible that the current download will not be completed due to the
changes to the configuration taking immediate effect and an inconsistent configuration is
reported.
Example:
The download is started initially with the setting TP/ITP at 10 Mbps half duplex. If the
"Individual network setting" is now changed to 100 Mbps full duplex, the download cannot
be completed.

multicast (MC) in an industrial Ethernet subnet, RT frames can be delayed by long BC
frames or MC frames.
Among other things, these frames can be generated by the communications FCs AG_SEND
or AG_RECV.
With certain constellations, this can lead to a PROFINET RT communication abort. The
factors that influence this are the switch configurations ("switch depth"), the update time and
the MC/BC frame lengths.
You will find further information about the influencing factors as well as possible solutions in:

6.7 IP configuration
CP 343-1 Lean
Note
STOP on expiry of the lease
The CP changes to STOP and loses the previously assigned IP address if the DHCP server
does not extend it before expiry of the lease. All communication connections are terminated.
General rules
The CP supports the two modes explained below for timeofday synchronization:
● SIMATIC mode
● NTP mode (NTP: Network Time Protocol)
No automatic changeover to daylight saving time is defined in NTP. As a result, you may
need to implement this changeover using a program application.
Project engineering
For more detailed information on configuration, refer to the online help of the "Time-of-day
synchronization" parameter group and in Part A of the manual /1/ (Page 60).

Notes on configuration and operation
6.10 SNMP agent
The information on the properties of SNMPcompliant devices is entered in MIB files (MIB =
Management Information Base).
The CP supports data queries via SNMP in Version 1. It returns the contents of certain MIB
objects according to the MIB II standard, LLDP MIB, Automation System MIB and
MRP Monitoring MIB.
Further information
For more detailed information on working with MIB files, refer to the documentation of the
SNMP client you are using (example of an SNMP client: SNMP OPC server from
SIMATIC NET).
You will find more information on MIBs on the following SIMATIC NET Internet page:
15177711 (http://support.automation.siemens.com/WW/news/en/8797900)
Supported MIBs
The CP supports the following groups of MIB objects of the standard MIB II according to
RFC1213:
● System
● Interfaces
● Address Translation (AT)
● IP
● ICMP
● TCP
● UDP
● SNMP
The other groups of the MIB II standard are not supported:
● EGP
● Transmission
The CP also supports the LLDPMIB according to IEEE 802.1AB, the PROFINET expansions
of the LLDPMIB (see also IEC 61158106), the Automation System MIB and the
MRP Monitoring MIB.
Exceptions / restrictions:
CP 343-1 Lean
● Write access is permitted only for the following MIB objects of the system group:
– sysContact
– sysLocation
– sysName
A set sysName is sent as the host name using DHCP option 12 to the DHCP server to
register with a DNS server.
For all other MIB objects / MIB object groups, only read access is possible for security
reasons.
● Traps are not supported by the CP.

Notes on configuration and operation
6.11 Possible security gaps on standard IT interfaces: preventing unauthorized access
Note
We expressly point out that automation networks must be isolated from the rest of the
company network by suitable gateways (for example using tried and tested firewall systems).
We do not accept any liability whatsoever, whatever the legal justification, for damage
resulting from nonadherence to this notice.
If you have questions on the use of firewall systems and IT security, please contact your
local Siemens office or representative. You will find the address in the SIMATIC catalog IK PI
or on the Internet at the following address:
(http://www.automation.siemens.com/partner/guisearch.asp)
Note
If the CP is in PG STOP mode and the configuration is downloaded using IP_CONFIG, the
CP then changes automatically to RUN.

Service and maintenance 7
7.1 Memory reset / reset to factory defaults
If the CP was configured with the "Status-dependent" protection level, the following two
functions are available only when the CPU is in STOP mode. You will find a setting in the
properties dialog of STEP 7 > "Options" > Module access protection tab.
Available functions
The CP has a twolevel function available for resetting memory:
● Memory reset
Following this memory reset, the CP retains the preset MAC address and the retentive
parameters. The CP is therefore immediately ready for downloads using the IP address.
The retentive parameters include:
– IP address, subnet mask and, if applicable, router address
– LAN settings
● Reset to factory settings
After resetting, the CP only contains the default MAC address (as shipped).
Note
The functions for memory reset and resetting to defaults described here do not change
the configuration data on the CPU!
If you subsequently upload the configuration data from the CPU to a PG you will always
obtain the configuration data that was previously on the CP (with parameters,
connections, IP address).

7.3 Replacing a module
If the loading with the firmware loader is interrupted, you should react as follows:
Disturbances or collisions on the network can lead to packets being lost. In such cases, this
can lead to an interruption of the firmware download. The firmware loader then signals a
timeout or negative response from the module being loaded.
In this case, turn the station off and on again and repeat the download.
Note
Recommendation to reset address data if the use of the CP is changed
The following data is stored permanently on the CP:
IP parameters when using DHCP
If the CP has already been operated in your plant and you want to use it at a different
location in the plant, it starts up with the permanently configured parameters.
If the CP has been used previously in your plant or has been repaired, delete all stored data
by resetting to the factory settings.
Distinction
When replacing existing modules with the module described here, the following variants
must be distinguished:
● Replacing a module
Describes the situation when an existing module can be replaced with a new module
simply by pulling/plugging without changing the configuration.
● Upgrading
(module replacement with compatible functions)
Describes the situation when the module described here can be used instead of an older
module as long as adaptations are made to the configuration. Here, the previously used
CP needs to be replaced in the configuration by the new CP.
Unless otherwise specified, the range of functions of the older module continues to be
supported.
You can also upgrade modules listed in "Module replacement". This is necessary when new
characteristics that were not available in the previously used module are required.
CP 343-1 Lean
Replacing a module
The CP 343-1 Lean described here (6GK7 343-1CX10-0XE0 firmware version 3.0) can be
used as a replacement for the following predecessor products:
● CP 343-1 Lean (6GK7 343-1CX00-0XE0)
When replacing a CP 343-1 Lean (CX00) with a CP 343-1 Lean (CX10) and a STEP 7
version < V5.4, all the previous functions remain available. Any port settings made for
Ethernet are adopted for port 1.
The additional second RJ-45 port is also available in the "Automatic setting" mode.
● CP 343-1 Lean (6GK7 343-1CX10-0XE0, firmware version V1.0, V2.x)
All previous functions remain available. In addition, the new functions compared with the
firmware version of the previous product are also available.
Upgrading
The following predecessor products can be upgraded on the CP 343-1 Lean
(6GK7 343-1CX10-0XE0) described here.
Refer to modules in "Replacing modules".
Note
You should always use the latest block versions for new user programs. You will find

7.3 Replacing a module
Module replacement
Please follow the procedure below when replacing an older module with the module
described here:
CP 343-1 Lean
Note
When replacing modules, please remember that the factoryset MAC address of the new
module is different from the previous module. When the factoryset MAC address of the new
module is sent to the DHCP server, this will return either a different or possibly no IP
address.
Ideally, you should therefore configure IP as follows:
Always configure a client ID if you want to obtain the same IP address from the DHCP server
after replacing the module.
