Technical data of product parameters

The principle of fault tolerance in the redundant processor units is based on PDD205A1121 3BHE025335R1121
continuous updating of the backup unit to the same status as the primary unit. This
enables the backup unit to assume control without affecting surrounding systems in
a bumpless manner.
This principle involves dynamic division of the program execution into execution
units and the creation of rollback points at which the processor unit’s status is
completely defined.
In this context, the processor unit’s total status is defined as the processor unit’s
internal status, that is, the contents of the processor registers, plus the contents of the PDD205A1121 3BHE025335R1121
data memory.
The backup unit’s status is updated each time the primary unit passes a rollback
point, enabling the backup unit to resume program execution from the last rollback
point passed, should the primary unit fail due to error.
In order to minimize the amount of information involved in the update, the backup PDD205A1121 3BHE025335R1121
unit is updated only with the changes taking place since the latest rollback point.
Between rollback points, these changes that writes in the data memory, are stored in
a log buffer in the backup unit. At a rollback point, the processor’s total register
contents are also written into the data memory, so that this information is also
logged. Once the rollback point is established, the logged write operations are
transferred to the backup unit’s data memory
