Automation
systems
The SIMATIC PCS 7 process control system always offers a suitable
solution for low-cost, effective implementation of batch
processes:
■ Simple batch processes with parameterizable sequential
controls are automated using the SFC and CFC tools included
in the engineering system.
■ SIMATIC BATCH is the user-friendly solution for more complex
tasks with recipe-controlled operation. This allows
simple, flexible processing of complex tasks that incorporate
changing control sequences.
Modular architecture
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 with 150,
300, 600, 1800 and >1800 batch process objects (instances
of plant units and equipment modules).
With small applications, e.g. for laboratory automation,
SIMATIC BATCH can also be combined with the PC-based
starter system SIMATIC PCS 7 BOX. The capacity of SIMATIC
BATCH is limited to 150 batch process objects 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 completely integrated in SIMATIC PCS 7.
The plant data can be configured entirely using the engineering
system. This passes on all data required for recipe creation
to the batch server, making recipe processing possible separate
from the engineering system. Changes to the configuration
which are made on the engineering system are available
to the batch server using an update function.
Depending on the load on the operator system, the batch
server software can also be executed on the OS server. However,
it is usually executed on separate server hardware (batch
server), isolated from the OS servers. SIMATIC BATCH clients
and OS clients can run on separate or common basic hardware.
The PCS 7 operator stations relevant to the batch are
passed on to the batch server during configuration of the
batch applications.
Communication with the automation systems
SIMATIC BATCH communicates with the automation systems
through the PCS 7 operator system. Operator instructions and
dialogs can also be integrated into the communication. These
permit additive data inputs (e.g. for laboratory values) or references
to necessary operator inputs. SIMATIC BATCH provides
special faceplates for controlling and monitoring plant
units and equipment modules.
SFC instances derived from an SFC type are generally used as
the interface to the subordinate automation level. The properties
of the SFC type, such as modes of operation, setpoints/actual
values, instance parameters, times etc. can be defined
through a properties dialog.
