The modularity and flexibility of SIMATIC BATCH are optimally supported by the hardware available. The basic hardware from the Section "SIMATIC PCS 7 Industrial Workstation" in the Chap- ter "System-neutral components" can be used for SIMATIC BATCH. Please note that the operating system and the ES/OS software of the SIMATIC PCS 7 process control system are pre- installed as standard on the single station, server or client as the basic device. If these basic devices are used for SIMATIC BATCH, it is possible to extend or reject the existing SIMATIC PCS 7 installation, and restore it for the operating system using the restore DVD.

Hardware for small plants

For small plants, SIMATIC BATCH can be installed together with the OS software on a single station system. You can find further details on the hardware for this OS/BATCH single station with the ordering data of this section:

•In the Section "SIMATIC PCS 7 Industrial Workstation" of the Chapter "System-neutral components"

•In the Section "OS hardware" in the Chapter "Operator system"

A further alternative for small plants is operation of SIMATIC BATCH on the starter system SIMATIC PCS 7 BOX 416.

Client/server configuration

Batch process automation typically has a distributed cli- ent/server configuration with one batch server and several batch clients, which together process a plant project. The batch server of such a configuration can also be configured with redundancy in order to increase availability.

SIMATIC BATCH clients and OS clients can run on separate or common basic hardware. The batch server software is usually executed on separate server hardware (Batch Server). Depend- ing on the load on the operator system, the OS and batch server software can also be executed on common server hardware (OS/Batch Server).

Since the batch server is only a node on the OS-LAN, we recom- mend that only the server version of the SIMATIC PCS 7 Indus- trial Workstation with BCE communication is used. The 10/100/1000 Mbit/s Ethernet RJ45 port is already onboard and can be used for connecting to the OS LAN.

Redundancy
The batch server redundancy is supported by the SIMATIC
BATCH basic package. The two batch servers of a redundant
pair of servers have identical configurations. Contrary to the
case of OS redundancy, they must always be connected via a
separate Ethernet connection in order to optimize the internal
communication. Since the batch server is not usually connected
to the plant bus, the Ethernet network card of the SIMATIC PCS 7
Industrial Workstation which is provided as standard for the plant
bus connection can be used for the redundant communication.
An optical or electrical connection can be used depending on
the environmental conditions and the distance between the two
batch servers, e.g. up to 100 m per crossover network cable
(RJ45 connectors). For details, refer to Manual "SIMATIC PCS 7
V7.0 fault-tolerant process control systems"; for appropriate ca-
ble material and further accessories, refer to Catalog IK PI.	6
If the SIMATIC BATCH software and the SIMATIC PCS 7

OS software are installed together on a redundant pair of serv- ers, the two servers must be connected together via an addi- tional desktop adapter network card for the redundant commu- nication. The serial RS 232 connection described in the Section "OS redundancy" is omitted.

For information and components for connection to a redundant terminal bus, see page 9/28.

Expansion options

The basic hardware is expandable according to the customer’s particular requirements and whether the hardware is used as single station, server or client with the following options:

•Multi-VGA graphics card for connection of up to 4 monitors

•Process monitors (see Spage 2/17)

The multi-VGA graphics cards "2 Screens" and "4 Screens" are offered for multichannel operation of an OS/batch single station or a batch client with 2 up to 4 process monitors. Using a multi- VGA graphics card, the visualization of the plant/unit can be di- vided among up to 4 process monitors per operator station by using different views. These plant sections can all be operated using just one keyboard and one mouse. The multi-VGA graph- ics cards are compliant with the EN 55022 and EN 50082 stan- dards. Each card occupies one PCI slot.

Note:

Since all messages from SIMATIC BATCH are processed in the operator system’s message system, the use of a signal module is only recom- mendable with multi-function OS/batch stations (clients, single stations).
