Networking configuration
The fault-tolerant S7 connection is a separate connection type of the "Configure Networks"
application. It permits that the following communication peers can communicate with each
other:
● S7–400 fault-tolerant station (with 2 fault-tolerant CPUs)->S7–400 fault-tolerant station
● S7–400 station (with 1 fault-tolerant CPU)->S7–400 fault-tolerant station (with 2 fault-
● S7–400 station (with 1 fault-tolerant CPU)->S7–400 station (with 1 fault-tolerant CPU)
● SIMATIC PC stations > S7–400 fault-tolerant station (with 2 fault-tolerant CPUs)
When this connection type is configured, the application automatically determines the
number of possible connecting paths:
● If two independent but identical subnets are available and they are suitable for an S7
● If only one subnet is available, four connecting paths are used for a connection between
Downloading the network configuration into a fault-tolerant station
The complete network configuration can be downloaded into the fault-tolerant station in one
operation. The same requirements that apply for downloads into standard stations must be
met.
