Features / Services
B2–4 CP 343-5 for PROFIBUS / Manual Part B2
Release 11/2002
C79000-G8976-C160-02
Features / Services
Application
The CP 343-5 communications processor is designed for operation in a SIMATIC
S7-300 / C7-300 programmable logic controller. It allows the S7-300 / C7-300 to be
attached to a PROFIBUS fieldbus system.
Services
The current version of the CP 343-5 supports the following communication
services:
SPROFIBUS–FMS (complying with EN 50170, FMS client and server
functionality)
as FMS master for the following types of connection:
– MMAC: Master–master acyclic
– MSAC: Master–slave acyclic
– MSAC_SI: Master–slave acyclic with slave initiative
– MSCY: Master slave cyclic
– BRCT (broadcast): Sending to all FMS stations
SS7 communication and PG/OP communication
– PG functions with upload / download of FM modules, configuration /
diagnostics and routing
– operator control and monitoring functions (HMI)
– server for data exchange on one-sided configured connections without
communication blocks in the S7 station
SS5–compatible communication (SEND/RECEIVE interface) over FDL
connections of the following type:
– specified FDL connections
– Free layer 2 connections (SDA, SDN)
– Broadcast
– Multicast
The CP 343-5 services mentioned above can be used at the same time
independently from one another.
Configuring
STEP 7 from version V5.1 SP3 and higher, and the installation of the NCM for
PROFIBUS optional package, delivered with STEP 7, are necessary for
configuration.

Features / Services
B2–5
CP 343-5 for PROFIBUS / Manual Part B2
Release 11/2002
C79000-G8976-C160-02
The module can be configured via the MPI or LAN/PROFIBUS.
Note
If you change the bus parameters in the configuration data, you can only download
these configuration data to the CP via the MPI.
Programming – Using Blocks
”Off–the–peg” blocks (FCs/FBs) form the interface in your STEP 7 user program to
some of the communication services available with the PROFIBUS CP. You will
find a detailed description of these blocks in the NCM S7 for PROFIBUS 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 on the Internet:
http://www4.ad.siemens.de/view/cs/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.
Replacing a Module without a Programming Device
The CP supports the option of storing the configuration data of the CP in the CPU.
If you use this option, you can replace the module without having to reload the
configuration data from the programming device.
The configuration data are then stored in the load memory of the CPU. The stored
configuration data are protected from power outage by battery backup or by
plugging an EPROM card into the CPU.

Installation and Commissioning
Procedure / Steps
Table 2-1
Step Comments
1. Install the CP on the S7 standard rail.
2. Establish the connection to the backplane bus
using the enclosed bus connector.
You can use slots 4 to 11 in racks 0 to 3 for the CP
(connected by IM 360/361).
Proceed as explained in the sections on installation
and wiring, described in detail in /1/ .
Note
The CP cannot be used in an expansion rack connected by an IM 365! Reason: The IM 365 does not
connect the required communication bus through to the expansion rack.
3. Connect the CP to the power supply. To wire up the power supply and CPU, follow the
detailed instructions in /1/.
Notes
SThe CPU, CP and IM (if used) must be connected to the same power supply.
SOnly wire up the S7-300 / C7-300 with the power switched off!
SWhen shipped, the CP has a jumper inserted between the M terminals and the functional ground. If
you want to ground the reference potential, do not remove the jumper between the M terminals and
functional ground (see also /1/ particularly the sections on installing an S7-300 with a grounded
reference potential and installing an S7-300 with an ungrounded reference potential).
4. Connect the CP to PROFIBUS.
5. Commissioning is completed by downloading
the configuration data. For further details, especially regarding node
initialization, please refer to /2/.

Controlling the Operating Mode
There are different ways in which you can control the mode of the CP 343-5, as
follows:
SMode selector
SNCM S7 for PROFIBUS configuration software
SSIMATIC Manager in STEP 7
To control the mode from STEP 7 / NCM S7 for PROFIBUS, the mode selector
must be set to RUN.
Mode Selector
With the mode selector, you can set the following modes:
SSwitch from STOP to RUN:
The CP reads the configured and/or modified data into the work memory and
then changes to the RUN mode.
SSwitch from RUN to STOP:
The CP changes to the STOP mode. Established connections (FDL, FMS and
S7 connections) are closed.
In the STOP mode, configuring and performing diagnostics on the CP 343-5 are
possible.
Note
Refer to the information on downloading the database to the CP in the manual /2/.

Performance Data
4.1 Supported Transmission Rates
The transmission rate is set with the SIMATIC STEP 7 configuration software. For
permitted values, see Table 6-1 in Section 6.
4.2 Characteristics of FMS Connections
The following data are important for operating FMS connections:
Table 4-1
Component Explanation / Values
Number of FMS connections Maximum of 16
User data length 237 bytes for READ
233 bytes for WRITE and REPORT
Configurable variables 256 server variables and 256 variable descriptions
that can be loaded from the partner. These can be
distributed as required on the maximum number of
configurable FMS connections. The value applies
to elementary data types or arrays of elementary
data types.
This value does not apply to complex data types
(STRUCT)! Note the information in the manual /2/
about using complex data types (STRUCT).
Cycle Load Caused by FMS Connections
When calculating the reaction times with FMS connections, the run time of the
function blocks (FBs) in the S7-300 CPU (314-1 see Table 4-2 ) is the decisive
factor.
The table below shows the cycle load resulting from the available FCs in ms. The
values were obtained using a data length of 230 bytes (array).

Further Notes on FMS
Please note the following:
In FMS server mode, the CP occupies an unconfigured communication bus
connection on the S7 CPU.
Note that the S7 CPU 314 supports a maximum of 4 (newer CPU types a
maximum of 12) unconfigured K bus connections! If, for example, you operate a
PG and an OP with the S7 CPU, two unconfigured K bus connections are still free.
Note
To allow module replacement without a PG, settings on the CPU must be
modified. Open the Properties dialog of the CPU in HW Config; in the “Monitoring
time for...” box in the “Startup” tab, check and, if necessary, increase the following
values:
– “Transfer of parameters to modules”
Depending on your system (station configuration), you may need to increase the
following parameter:
– “Ready message from modules”
