CP 443-5 Basic for PROFIBUS / Manual Part B3
Release 11/2002
C79000-G8976-C161-04
Properties / 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 fieldbus system.
Services
The current version of the CP 443-5 Basic supports the following communication
services in the standard and H systems:
S PROFIBUS FMS (complying with EN 50170, FMS client and server function)
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
S S7 communication and PG/OP communication
- PG functions with upload / download of FM modules, configuration /
diagnostics and routing, user programs
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)

CP 443-5 Basic for PROFIBUS / Manual Part B3
Release 11/2002
C79000-G8976-C161-04
S S5-compatible communication (SEND/RECEIVE Interface) over FDL
connections of the following types:
- specified FDL connections
- free layer 2 connections
- broadcast
- multicast
S 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.
Configuration
When configuring, you must use STEP 7 version V5.2 SP1 or higher; for FDL
connections and diagnostic functions, the NCM S7 for PROFIBUS optional
package supplied with STEP 7 must be installed.
If the functionality of the predecessor module is adequate for your purposes,
configuration and diagnostics are also possible with earlier STEP 7 versions.
It is possible to configure over the MPI or LAN/PROFIBUS.
System modifications are possible during operation (H system).
Note
For more detailed information on configuring PROFIBUS CP with STEP 7 /
NCM S7, refer to the manual NCM S7 for PROFIBUS and the online help of
STEP 7.
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.
