(1) Redundant BATCH server
Redundancy is achieved with two BATCH servers with a standby/master failover. The
redundancy of the BATCH servers ensures the following if a BATCH server fails:
● All BATCH clients (with the BATCH Recipe Editor and BatchCC (batch planning, batch
control)) are immediately operable again following the failover and
● permanent acquisition of the Batch data continues.
(2) OS redundancy of the standard PCS 7 operator stations
The redundancy of the distributed PCS 7 operator stations with an interface to the SIMATIC
S7-400 is achieved by interconnected OS servers with data synchronization and backup of
the archive data. The WinCC archives of the redundant OS servers are synchronized and
contain the same data. The functionality is implemented with the "Redundancy" optional
software of WinCC. For a description of the "Redundancy" optional software, refer to the
manual
SIMATIC HMI; Options
.
The redundancy of the PCS 7 operator stations ensures that the batch processes will continue
uninterrupted even if one of the two OS servers fails. The operator remains informed about
the status of the process cell and can still intervene in the process.
