15.8
Usable networks
Your choice of the physical transmission medium depends on the required expansion,
targeted fault tolerance, and transfer rate. The following bus systems are used for
communication with fault-tolerant systems:
● Industrial Ethernet
● PROFIBUS
Additional information on the networks that can be used is available in the relevant SIMATIC
NET documentation on PROFIBUS and Ethernet.
15.9
Communication via S7 connections
Communication with standard systems
There is no fault-tolerant communication between a fault-tolerant system and a standard
CPU. The following examples illustrate the actual availability of the communicating systems.
Configuration
S7 connections are configured in STEP 7.
Programming
If S7 communication is used on a fault-tolerant system, all communication functions can be
used for this.
The communication SFBs are used in STEP 7 to program communication.
Note
The START and STOP communication functions act on exactly one CPU or on all CPUs of
the fault-tolerant system. More detailed information is available in Reference Manual

Note
Downloading the connection configuration during operation
If you download a connection configuration during operation, established connections may
be terminated.
