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 V5.1 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:
S STEP 7 version 5.0 Service Pack 3
This version is the minimum requirement for the routing of PG functions and
time-of-day synchronization.
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;
