1 Properties / Services
S 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)
- Client and server for data exchange on S7 connections via communications
function blocks (fault-tolerant S7 connections also possible)
- Download S7 connections and gateways in RUN.
S Time-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)
S Data 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.
