Hello, maybe there's a little misunderstanding... Which station do you mean? PLCs or PCs? Thefault-tolerantCPUs (H type) are interconnected via the syncmodule (2 pcs in each CPU) and fibre-optic cables. In the redundant mode are both CPUs in RUN mode and synchronized so if one of them fails the second will continue. The redundant OS servers also runs together and synchronized, clients connects to the preferred server, if fails they try to connect to the redundant one. The connection between them is done by the serial link. S7-REDCONNECT is used in PC for theredundant S7 communicationwith the fault-tolerant PLCs through redundant or non redundant network.
