Preface
Preface
The SIMATIC automation system unites all of the subareas of an automation solu-
tion under a uniform system architecture to form a homogenous whole from the
field level right up to process control.
The Totally Integrated Automation (TIA) concept permits uniform handling of all
automation components using a single system platform and tools with uniform
operator interfaces. These requirements are fulfilled by the SIMATIC automation
system, which provides uniformity for configuration, programming, data manage-
ment, and communication.
This book describes the SIMATIC S7-1500 automation system. S7-1500 controllers
are compact in design and can be modularly expanded. The CPUs feature integrated
bus interfaces for communicating with other automation systems via Industrial
Ethernet and, depending on the type of module, via PROFIBUS DP as well.
The STEP 7 Professional engineering software in the TIA Portal makes it possible to
use the complete functionality of the S7-1500 controllers. STEP 7 Professional is the
common tool for hardware configuration, generation of the user program, and for
program testing and diagnostics.
STEP 7 Professional provides five programming languages for generation of the
user program: Ladder logic (LAD) with a graphic representation similar to a circuit
diagram, function block diagram (FBD) with a graphic representation based on
electronic circuitry systems, a high-level Structured Control Language (SCL) simi-
lar to Pascal, statement list (STL) with formulation of the control task as a list of
commands, and finally GRAPH as a sequencer with sequential processing of the us-
er program.
STEP 7 Professional supports testing of the user program by means of watch tables
for monitoring, control and forcing of tag values, by representation of the program
with the current tag values during ongoing operation, and by offline simulation of
the programmable controller.
This book describes the configuration, programming, and testing of a CPU 1500 V2.0
programmable controller using the STEP 7 Professional V14 engineering software
and the S7-PLCSIM V14 simulation software.
