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:

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

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) 1 )

CP 443-5 Basic for PROFIBUS / Manual Part B3

Release 11/2002

C79000-G8976-C161-04

Properties / Services

S5-compatible communication (SEND/RECEIVE Interface) over FDL

connections of the following types:

- 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.

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.
