Objectives The goal of the new concept is to provide system
operators with the most comprehensive advantages for using
automation concepts.
Utilization is most effective when there is as much continuity and
integration as possible for automating all subsystems from the
front end to the back end, including the production management
level.

Totally Integrated Automation
1FT6/1FK6
TIA Totally Integrated Automation (TIA) is not a product or system
you can obtain with a purchase order number. TIA is a
Siemens-internal concept for integrating all automation components.
All of the individual products and systems in the “Totally
Integrated Automation“ family have been created and designed so
that any component combination provides advantages that non-Siemens
component combinations cannot offer.
Openness TIA also stands for openness. You can, of course, connect
third-party devices at any of the system levels. However, you can
integrate components from the Totally Integrated Automation family
more effectively (functionality) or at less cost (engineering) into
the total configuration.
TIA Product Range The TIA range currently consists of the following
product groups:
SIMATIC controllers
SIMATIC PCS 7
SIMATIC PCS7 is a member of the TIA product range, in addition to
the above listed systems.

The viewpoint from the different areas involved is that a
conventional solution for this type of automation calls for special
hardware and software solutions.
These solutions include PLC-based ones for the upstream and
downstream area, PCS-based solutions (Process Control System) for
the actual process, and PC-based or workstation-based solutions for
the information processing area.

What Is Process Control?
Process Control = Automation + HMI + communication
In Components Automation System (AS) + HMI system (OS - Operator
Station) + bus

The SIMATIC Process Control System 7 is based on the SIMATIC - S7
400 CPUs.
The modular structure of the SIMATIC controller range allows you to
develop a solution tailored to your needs and special applications
as a complement to SIMATIC PCS 7.
You can select the appropriate performance class: from the S7 200
to the S7 400. You can also choose the correct functionality:
Process automation (S7) or information processing (M7).
For example, you could use SIMATIC C7, a compact combination of
automation, operating and monitoring functions, if you need
compact, stations installed at the machine location.

SIMATIC S7-400F/FH with ET 200M
AS 414 H and AS 417 H
are high-availability automation systems, so-called 1-of-2 systems
that reduce the probability of production downtime by switching to
an internal reserve system. The automation system is designed with
internal redundancy to allow it to be available at all times. This
means:
All critical components such as
central processing unit, power supply
hardware for connecting both central processing units
are fitted in pairs.
Which components you decide to double for higher availability in
addition to the ones above will depend on the specific automation
task.
AS 414 F/FH and AS 417 F/FH
A fault-tolerant system continuously checks it is operating without
errors. If it detects an error, it will initiate steps to ensure
the process is in a safe state.
The AS 414 F/FH and AS 417 F/FH automation systems are
fault-tolerant systems. If required, they can also be configured as
redundant systems in order to increase availability in addition to
the fault tolerance.
In addition to the central processing unit, the F package includes
the F signal modules SM 326F and SM 336F for ET 200M, an F
programming tool and a runtime license. The new ProfiSafe profile
is used for failsafe communication between the CPU and I/Os via
PROFIBUS DP. An additional safety protocol ensures failsafe data
transmission parallel to the standard communication.

HMI (Human Machine Interface)
A universal, scalable system is required to operate and monitor
processes.
This is why we are providing modularly graduated systems with
various performance ranges.
- One of our systems has UNIX-based solutions, derived from our
experiences with existing systems.
- Another system solution offers the WINDOWS-based WinCC.
These systems form the basis for the OS (Operator Station),
integrated from the low-performance end to the high-performance
end.
The special features are that the systems have the same operating
basis and a common engineering system.

Communication via Fieldbus/System Bus:
SIMATIC NET
M
Field Level PROFIBUS DP, PA, or the AS-interface is used to connect
the distributed peripherals or I/Os (field devices and the
ET200M).
System Bus Depending on the performance you need, you can use one
of the MPI, PROFIBUS or ETHERNET versions as a system bus. They
handle AS, OS and ES communication.
Caution! With PCS 7 Version 5 and higher, we recommend using only
Ethernet as the system bus for new installations. You can still use
PROFIBUS as the system bus for expanding legacy networks.

SIMATIC NET - Which Bus for Which Task?
MPI (only for test purposes)
Communication for small to medium-sized systems
Integrated programming interface for the controller
PROFIBUS (small configurations only)
Fast system bus for medium- to large-scale configurations

PROFIBUS PA This is an extension of the PROFIBUS DP. The DP/PA

SIMATIC PCS 7 - Engineering Toolset
Plant- and system-wide engineering is the key for efficiently
automating industrial engineering processes.
The integral concept in the SIMATIC Process Control System 7
provides the optimum tool for every task in every configuration
phase.
The common database is one of the outstanding
characteristics.
The appropriate tool is used to define functions once only. The
functions are then available on a system-wide basis.

Block Libraries You do not have to program to solve automation
tasks. PCS 7 has libraries with pre-compiled solutions, called
blocks. These blocks cover the typical process industry
applications. The project planning engineer must be familiar only
with the input/output interfaces and a block‘s functionality. The
project planning engineer does not have to be concerned with how a
block is programmed.
Batch-Flexible An extensive software package is offered for batch
processes. This package provides the functions necessary from batch
and device planning up to integration at the plant control level
and automation level.

Although the hardware and software components can communicate with
each other in the framework of the TIA family, additional
integration is required. The components provided within the PCS7
framework have already passed the integration test; they are
adapted to one another and can be used without any additional
adaptations.
In this environment, project planning engineers can dedicate
themselves to the actual task at hand: automating a process - from
the field level to the plant control level.
