Technical data of product parameters

If the primary unit fails because of an error, the backup unit resumes execution from PDD500A101 3BHE037649R0101
the last rollback point, which means the last execution unit is partially re-executed
by the backup unit. In order to re-execute a portion of the execution unit without
affecting the peripheral units (communication units on the CEX-Bus), the peripheral
units’ references are also logged between rollback points. During re-execution, the
results of the peripheral units’ references, which have already been executed, are PDD500A101 3BHE037649R0101
used, rather than re-executing them. The results of read operations are retrieved
from the log, and write operations pass without execution, since they have already
been executed. The peripheral units’ statuses, then, are not affected by the reexecution in any way, except for the time delay which occurs.
The RAM included in the processor unit provides an automatic double inverted
memory function for detection of arbitrary bit errors in the memory.
• All memory updates are written to both the primary memory and to the inverted
memory in parallel.
• At every memory read cycle, the data from tho two memories is compared. PDD500A101 3BHE037649R0101
• If there is a mismatch in the data a changeover is forced.
The double inverted memory handling is done in hardware and without any delay to
the memory cycle time.
