Properties / Services
S STEP 7 version 5.1 Service Pack 3
All the functions described can be used.
When configuring fault-tolerant systems you must also install the "SIMATIC S7
H Systems" optional package.
It is possible to configure over the MPI or LAN/PROFIBUS.
System modifications are possible during operation (H system).
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.
Notice
We recommend that you always use the latest block versions for all module types.
You will find information on the latest block version and links to download the
current blocks in our Customer Support on the Internet:
http://www4.ad.siemens.de/view/cs/en/8797900
If you are using older block types, this recommendation only applies if you also
have the latest firmware version.
You will find further information and Internet addresses in the Preface of the
General Part of this manual.
Module Replacement without PG
Depending on the setting in the project configuration, the configuration data can
also be stored in the load memory of the CPU. Therefore replacing modules is
possible without having to download the configuration data from the PG.
The stored configuration data are protected from power outage by battery backup
or by plugging an EPROM card into the CPU.
