Features / Services

Application

The CP 443-5 Basic 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 field bus system.

Services

The current version of the CP 443-5 Basic supports the following communication

services in the standard and H systems:

FMS Connections

PROFIBUS–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

S7 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)

–

Data exchange using communication function blocks on S7 connections

(fault-tolerant S7 connections also possible) 1 )

Features / Services

S5–compatible communication (SEND/RECEIVE interface) over FDL

connections of the following type:

–

specified FDL connections

–

free layer 2 connections

–

broadcast

–

multicast

Time–of–day Synchronization over 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.

–

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

synchronization status

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

time.

PG Functions with

upload / download of FM modules

configuration / diagnostics

routing

Configuration

When configuring, you must use STEP 7 version V5.1 SP2 or higher; for FDL

connections and diagnostic functions you must already have installed the NCM S7

for PROFIBUS optional package, delivered with STEP 7. Depending on the version

you are using, note the following characteristics and special features:

STEP 7 version 5.0 and higher Service Pack 2

This version is the minimum requirement for the routing of PG functions and

time-of-day synchronization.

STEP 7 version 5.0 Service Pack 3 Hotfix 3

The optional package “SIMATIC S7 H Systems” must also be installed to

configure fault-tolerant systems.

The following functions of the CP are not yet supported in this configuration

environment when using fault-tolerant systems:

–

Single (non-redundant) communications connections cannot be configured in

a fault-tolerant system;

STEP 7 version 5.1

When configuring fault-tolerant systems you must also install the “SIMATIC S7

H Systems” optional package.
