Names
In this document, the term "CP" is used instead of the full product name.
The name STEP 7 is used for the configuration tool instead of the names STEP 7 V5.5
and STEP 7 Professional.
Innovations and compatibility with the predecessor product
Note
You will find the new functions of the module in the section Enhanced functions (Page 9).
Make sure that you read the information relating to enhanced functions and restrictions that
may apply in the section Module replacement / upgrading (Page 56).
Address label: Unique MAC address preset for the CP
The CP ships with a default MAC address. The MAC address is printed on the housing.
Address label: Unique MAC address for the CP
The CP is supplied with total of 3 default MAC addresses with the following assignment:
● PROFINET interface
● One MAC address for each of the 2 Ethernet ports of the PROFINET interface
The MAC addresses of the Ethernet ports are required only for detection and evaluation
of neighborhood and topology relations.
The MAC address of the PROFINET interface is printed on the housing.
If you configure a MAC address (ISO transport connections), we recommend that you use
the MAC address printed on the module for module configuration!
● This ensures that you assign a unique MAC address in the subnet!
● If you replace a module, the MAC address of the predecessor is adopted when you load
the configuration data; configured ISO transport connections remain operable.
You should also refer to the information in the section Replacing a module (Page 55).

CP 343-1
Manual, 10/2012, C79000−G8976−C201-07 9
Properties / services 1
1.1 Application
The CP 343-1 communications processor is intended for operation in a SIMATIC S7-300,
SIMATIC C7-300 automation system or SINUMERIK 840D power line. 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.
1.2 Enhanced functions
Abbreviations used with the CP 343-1 module
The module abbreviations used below for the CP 343-1 (for example EX30) correspond to
the last four characters of the mid section of the order number.
Requirement for configuring new functions of firmware version V3.0
To use the features listed below, the following STEP 7 version is necessary:
● STEP 7 V5.5 + Service Pack 2 + Hotfix 1 + HSP 1057
With STEP 7 Professional V11.0 SP2, only the functions of firmware version V2.2 of the CP
can be configured.
Functional enhancements of the EX30 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 as PROFINET IO device and as IO controller
● 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 70).
Properties / services
1.3 Communication services
CP 343-1
10 Manual, 10/2012, C79000−G8976−C201-07
● New program block FB10 AG_CNTEX for connection diagnostics
● Configuration of the IO devices in the STEP 7 "I-device" dialog box (and as previously
using a GSDML file)
Functional enhancements of the EX30 with firmware version V3.0 - regardless of the configuration
tool used
● Advanced Web diagnostics (HTTP access) with the following additional options:
– Diagnostics of S7 connections
– Module identification
– Expansion of Web diagnostics for The "Shared device" function
● Update center of Web diagnostics with the following functions:
– Downloading firmware via the Web (HTTP access)
– Downloading of language files for diagnostics buffer texts in STEP 7 format for new
modules in the rack and for changing the language
● SNMP: Support of the MRP Monitoring MIB
Enhanced functions of earlier firmware versions and predecessor modules
You will find an overview of the earlier firmware versions and predecessor modules in the
version history of the Industrial Ethernet CPs on the Internet pages of Siemens Automation
Customer Support under the following entry ID:
56699406 (http://support.automation.siemens.com/WW/view/en/56699406)
You will find information about the characteristics of the individual firmware versions on the
Internet pages of Siemens Automation Customer Support under the following entry ID:
43409748 (http://support.automation.siemens.com/WW/view/en/43409748)
> Entry list > Entry type "Updates"
1.3 Communication services
The CP supports the following communication services:
● PROFINET IO
PROFINET IO allows direct access to IO devices over Industrial Ethernet.
The CP can be used either as a PROFINET IO controller or as a PROFINET IO device,
but not both at the same time.
– PROFINET IO controller
IO controller mode with alarm block and acyclic data exchange by reading/writing a
data record.
– PROFINET IO device
Integration of the SIMATIC S7-300 automation system via the CP as an intelligent
PROFINET IO device (I-device).
