SIMATIC Industral Software - Tools for configuring and programming ...

Standard tools
STEP 7 Professional
The complete package at an affordable price
STEP 7 is the most recognized and widely used programming
software worldwide in the industrial automation
industry. Expanded to include additional important software
tools, STEP 7 Professional is the tool that will greatly
increase the productivity of your planning engineers.
STEP 7 Professional includes other important languages in addition
to STEP 7 Basis with the tried and tested programming
languages LAD, FBD and STL:
■ S7-GRAPH to program sequential controls
■ S7-SCL to program complex algorithms
which were rated so important by programmers that they
were also elevated to standard languages: IEC 61131-3 is the
quality standard for programming software recognized worldwide.
This standard is part of the curriculum of schools and
universities, so the know-how is widespread.
S7-PLCSIM additionally provides STEP 7 Professional with a
powerful engineering tool for program testing.
Worldwide programming standard
STEP 7 Professional is programming software for SIMATIC controllers
which complies with the IEC 61131-3 standard.
The international standard IEC 61131 is regarded as a worldwide
and future-oriented standardization in the area of
programmable logic controllers. It has been taken over as
European standard EN 61131. It replaces several national
standards.
Worldwide standardization has the following advantages:
■ Less software engineering overhead thanks to
cross-company standardization.
■ More efficient training and further training.
■ Application software can be ported to devices of different
manufacturers over the long term.
Several expansions of the programming languages were implemented
in compliance with the standards to offer the users
optimum programming comfort and the full utilization of the
functionality of the SIMATIC controllers.
Higher productivity with
STEP 7 Professional
■ One package – all IEC languages:
- STEP 7 with LAD, FBD, STL
- S7-SCL
- S7-GRAPH
- ... and for offline testing: S7-PLCSIM
■ Lower package price
■ Low outlay for installation and updating
■ Engineering workplaces with the same basic setup
increase productivity:
- Every employee working on the project
can work on any device.
- Every employee uses the tool, on which
he/she can be the most productive.
PLCopen: The organization
Different manufacturers and users of control and programming
systems have founded the international organization PL-
Copen, which promotes the use and distribution of programming
in accordance with IEC 61131. PLCopen aims to make
application software portable between the hardware of different
manufacturers.
Siemens is actively participating in PLCopen and has introduced
PLC programming to IEC 61131.
The certification of programming systems from different manufacturers
is an important prerequisite for making software
portable. To allow this, the standard compliance classes were
redefined by PLCopen:
■ Base level
■ Conformity level
■ Reusability level.
Independent institutes carry out the test procedures and issue
the respective certificates. Siemens has been awarded the
base level certificate for S7-GRAPH (SFC) and the base level
and reusability level certificate for S7-SCL (ST).
