Systems that use Hot Standby CPU Redundancy
Figure 14 shows a Hot Standby CPU Redundancy system that uses a PROFINET I/O network with
MRP ring topology. Use of MRP ring topology is recommended because it eliminates the I/O network
as a single point of failure. If elimination of a single point of failure is not required, a star topology can
be used.
These systems are described in the PACSystems Hot Standby CPU Redundancy User's Manual,
GFK-2308F or later.
