Product overview

2.1 Configuration and operating principle

Principle of operation

One of the two CPUs in the redundant system takes on the role of CPU for process control

(primary CPU). The other CPU takes on the role of the following CPU (backup CPU). The role

of the CPUs can change during operation. All relevant data is synchronized from the primary

CPU to the backup CPU via the fiber-optic cables of the redundancy connections.

Synchronization between the primary CPU and backup CPU ensures fast switching between

CPUs in the event of a primary CPU failure. If the primary CPU fails, the backup CPU retains

control of the process as the new primary CPU at the point of interruption.

The redundancy connections consist of two fiber-optic cables, which directly connect the

CPUs via plug-in synchronization modules.
