Process display with integrated OS Control

Integration in SIMATIC PCS 7

SIMATIC BATCH is completely 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 configuration which are made in the engineering system are available to the Batch server using an update function (online/offline).

SIMATIC BATCH supports the operation and monitoring of batch processes by means of standard faceplates (faceplates and OS controls integrated in the process picture). With SIMATIC PCS 7 V9.0, operation is also possible using OS controls configured on a Web client.

The SIMATIC Logon integrated in SIMATIC PCS 7 uses SIMATIC BATCH for the following functions:

• Central user administration with access control
• "Electronic Signature" function
  This means that actions cannot be performed until enabled by authorized users/user groups.

A smart card reader suitable as a logon device is offered in section "Industrial Workstation/IPC", "Expansion components, smart card reader".

Operating modes for recipe processing

• PC mode: Processing of the recipe logic in the batch server
• AS mode: Execution of recipe logic in the automation system
• Mixed operation: Parallel application of PC and AS modes in one batch (unit recipe-granular)

SIMATIC BATCH works as standard in PC mode. The complete control recipe is executed in the batch server. In the alternative AS operating mode, the control recipe logic can be executed in the automation system unit recipe-granular.

Advantages of AS mode are:

• Very fast step changing times
• Improved deterministics during execution of a batch
• Enhanced availability

Communication with the automation systems

Depending on the operating mode, SIMATIC BATCH communicates with the automation systems via the operator system or directly via S7-DOS.

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 properties dialog, including:

• Control strategies
• Setpoint/actual value
• Instance parameters
• Timers

In addition to the SFC instances, individual unit parameters can be described by parameter steps of the recipe.
