What is Siemens STEP 7 Professional and why you should use it
Siemens STEP 7 Professional is a software package that allows you to configure, program, test, and diagnose the Basic, Advanced and Distributed Controllers of all generations, whether PLC- or PC-based, including software controllers[^1^]. It is part of the TIA Portal, an integrated engineering framework that offers a consistent user interface and a range of functions for automation tasks[^1^].
With Siemens STEP 7 Professional, you can benefit from many features and advantages, such as:
A modern and intuitive graphical editor for ladder logic, function block diagram, statement list, structured text, and sequential function chart programming languages[^1^].
A powerful simulation tool (S7-PLCSIM) that allows you to test and debug your programs without connecting to a physical device[^1^].
A comprehensive library of ready-to-use function blocks and data types for various applications and technologies[^1^].
A seamless integration with other TIA Portal components, such as HMI software, SCADA software, drive parameterization software, and industrial communication software[^1^].
A flexible licensing model that allows you to choose the best option for your needs and budget[^2^].
A software update service that ensures you always have the latest version of the software and access to new features and improvements[^2^].
If you are looking for a reliable and efficient solution for PLC programming, Siemens STEP 7 Professional is the right choice for you. You can order it online from the Siemens Industry Mall or contact your local Siemens representative for more information[^2^].
In this article, we will give you an overview of some of the main features and functions of Siemens STEP 7 Professional and how they can help you with your PLC programming tasks.
The graphical editor of Siemens STEP 7 Professional allows you to create and edit your programs using different programming languages, such as ladder logic, function block diagram, statement list, structured text, and sequential function chart. You can switch between the languages easily and use the best one for your specific task. The graphical editor also provides you with a range of tools and options to make your programming easier and faster, such as drag-and-drop, copy-and-paste, undo-and-redo, syntax highlighting, auto-completion, online help, and more.
The simulation tool (S7-PLCSIM) of Siemens STEP 7 Professional allows you to test and debug your programs without connecting to a physical device. You can simulate the behavior and response of your PLC and the connected devices, such as sensors, actuators, and HMI panels. You can also monitor and modify the values of variables, inputs, outputs, timers, counters, and flags. The simulation tool helps you to save time and resources by detecting and correcting errors before deploying your programs to the real devices.
Function Blocks Library
The function blocks library of Siemens STEP 7 Professional provides you with a collection of ready-to-use function blocks and data types for various applications and technologies. You can use them to implement common functions and tasks in your programs, such as arithmetic operations, logic operations, conversions, comparisons, communications, diagnostics, motion control, PID control, safety functions, and more. You can also create your own function blocks and data types and store them in the library for future use. 061ffe29dd
