B4-4 CP 443-5 Extended for PROFIBUS / Manual Part B4

Release 6/2005

C79000-G8976-C162-06

1 Properties / Services

Application

The CP 443-5 Extended communications processor is designed for use in a

SIMATIC S7-400 (standard) and S7-400H (fault-tolerant system) programmable

controller. It allows the S7-400 / S7-400H to be connected to a PROFIBUS fieldbus

system.

You can use the CP as a router for data records intended for field devices (for

example PA slaves).

Services

The current version of the CP 443-5 Extended supports the following

communication services in the standard and H systems:

SPROFIBUS-DP with the following characteristics:

- DP master (class 1) (redundant operation in fault-tolerant system also

possible)

- Direct data exchange (DP slave to DP slave)

As a DP master, the CP 443-5 Extended is capable of enabling direct data

exchange for “its” DP slaves.

- SYNC /FREEZE (please refer to Tables 2-1 and 2-2)

The outputs or inputs can be synchronized from the within the user program

using system function SFC11.

- Constant bus cycle time (only in the standard system)

The ability to set a constant bus cycle time means that the DP master

always starts the DP bus cycle after the same interval.

- Selectable DP modes:

DPV1 functionality

(default in STEP 7) S7-compatible

DP master mode for:

SDP slaves complying with the

PROFIBUS DP-V0 and DPV1

standard

SSiemens DP slaves

(Refer to the information in Tables 2-1

and 2-2 on the required CPU)

DP master mode for:

SDP Slaves complying with the

PROFIBUS DP-V0 standard (DP

slaves complying with the DPV1

standard can only be used with

restricted functionality)

SSiemens DP slaves

(For more information on the topic of DPV1, refer to the STEP 7 / Hardware

Configuration online help)

Release 6/2005

- CiR (Configuration in RUN) - in the standard system

By making a change to the configuration with CiR (Configuration in RUN), it

is possible to put a DP slave / DP slot extension into operation or take it out

of operation when necessary while the system is running.

In other words, you can configure and activate additional DP slaves or DP

slots while the S7 station is in RUN.

- Activate/deactivate DP slaves in the standard system

DP slaves can be activated and deactivated from the within the user

program using system function SFC12.

- Diagnostic Requests

As a DP master class 1, the CP 443-5 supports diagnostic requests of a DP

master class 2.

- Identifying the bus topology in a DP master system

As a DP master, the CP 443-5 Extended supports the measurement of the

PROFIBUS bus topology in a DP master system using a diagnostic repeater

(DP slave).

System function SFC103 in the user program can instruct diagnostic

repeaters to measure the PROFIBUS BUS topology in a DP master system.

When completed, the results of the measurements made by the diagnostic

data can then be read in and processed by the user program.

SS5-compatible communication (SEND/RECEIVE interface) on FDL

connections of the following types:

- specified FDL connections

- free layer 2 connections

- broadcast

- multicast

Release 6/2005

C79000-G8976-C162-06

SS7 communication and PG/OP communication

- PG functions with upload / download of FM modules, configuration /

diagnostics and routing

Note on routing: Dynamic switchover to alternative paths (for example if

there is a problem on one of the possible transmission paths) is not

supported.

- Operator control and monitoring functions (HMI)

- Client and server for data exchange on S7 connections via communications

function blocks (fault-tolerant S7 connections also possible)1)

- Download S7 connections and gateways in RUN.

STime-of-day synchronization via PROFIBUS

- The CP forwards time-of-day synchronization frames from the LAN to the

station (CPU = time slave) or from the station to the LAN (CPU= time

master) or this station is synchronized via a different LAN and the

time-of-day synchronization frame must be forwarded over PROFIBUS for

the synchronization of further stations.

- The CP supports time stamping of distributed process signals in conjunction

with the IM 153.

- Time-of-day status value (standard/daylight saving time switchover,

synchronization status)

SData record routing

You can use the CP as a router for data records intended for field devices (for

example PA slaves). One tool that creates such data records for assigning

parameters to field devices is SIMATIC PDM (Process Device Manager; see

also SIMATIC PDM documentation...).

The services of the CP 443-5 Extended module listed above can be used at the

same time.

Project engineering

To configure and use any functions, you require STEP 7 as of V5.3.

It is possible to configure over the MPI or LAN/PROFIBUS.

Programming - Using Blocks

For some communication services, there are “off-the-peg” blocks (FCs/FBs)

available that implement the interface in your STEP 7 user program. 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 Modules without a Programming Device

When installing the CP 443-5 Extended, the configuration data of the CP are

always stored in the CPU. Therefore replacing modules is possible without having

to download the configuration data from the PG.

The stored configuration data is protected from power outage by battery backup or

by plugging a flash memory card into the CPU.
