Redundancy
The IS1+ Remote I/O system can also be implemented redundantly based on the
communication protocol. Here, a distinction is made between CPU redundancy,
power redundancy and system/full redundancy.
The following table shows the components required for the respective redundancy concepts:
Comply with the specifications for selecting the suitable 9496/32 socket and maximum
equipping of the 9442/32 CPU module and 9445/32 power module!
