Configuration
The availability of the system, including the communication, is set during configuration. Refer
to the STEP 7 documentation to find out how to configure connections.
Only S7 communication is used for fault-tolerant S7 connections. To set this up, open the
"New Connection" dialog box, then select "S7 Connection Fault-Tolerant" as the type.
The number of required redundant subconnections is determined by STEP 7 as a function of
the redundancy nodes. Up to four redundant connections can be generated, if supported by
the network. Higher redundancy cannot be achieved even by using more CPs.
In the "Properties - Connection" dialog box you can also modify specific properties of a fault-
tolerant connection if necessary. When using more than one CP, you can also route the
connections in this dialog box. This may be practical, because by default all connections are
routed initially through the first CP. If all the connections are busy there, any further
connections are routed via the second CP, etc.
You have to extend the monitoring time of the connection when you use long
synchronization cables.
