SIMATIC BATCH

Introduction

■Design ■Integration

6

SIMATIC BATCH is configured as a single-user system or as a client/server system, and can be used in plants of any size due to its modular architecture and scalability in 5 steps using 10, 20, 40, 100 and unlimited units (instances of plant units).

With small applications, e.g. for laboratory automation, SIMATIC BATCH can also be combined with the PC-based starter system SIMATIC PCS 7 BOX 416. The capacity of SIMATIC BATCH is limited to 10 units in this case.

However, characteristic for the automation of batch processes using SIMATIC BATCH are client/server architectures with which one batch server and several batch clients process a plant project together. The batch server can also be configured with redundancy in order to increase availability.

Integration in SIMATIC PCS 7

SIMATIC BATCH is fully integrated in SIMATIC PCS 7. The plant data can be configured entirely using the engineering system. The engineering system transfers all data required for creating recipes to the batch server. It is therefore possible to edit recipes separate from the engineering system. Changes to the configu- ration which are made on the engineering system are available to the batch server using an update function (online/offline).

The SIMATIC Logon integrated in SIMATIC PCS 7 implements the following functions:

•Central user administration with access control

•Function "Electronic Signature"

This means that operations cannot be performed until enabled by authorized Windows users/user groups.

Communication with the automation systems

SIMATIC BATCH communicates with the automation system through the operator system. The PCS 7 operator stations rele- vant to the batch are made known to the batch server during configuration of the batch applications. Operator instructions and dialogs can also be integrated into the batch-AS communi- cation. Attention is then drawn to necessary operator inputs, or data input is made possible, e.g. for laboratory values. SIMATIC BATCH provides special standard faceplates for controlling and monitoring plant units and equipment modules.

SFC instances derived from a SFC-type template are generally used as the interface to the subordinate automation level. The properties of the SFC type can be defined in a features dialog:

•Operations

•Setpoints/actual values

•Instance parameters

•Times etc.

It is also possible to use special batch interface blocks for com- munication with the processing programs in the automation sys- tems, e.g. for plant expansions or for connection of non-SIMATIC systems.
