The central editor for configuring hardware and networks
A complete plant can be configured using a single graphical editor. The editor offers three views to ensure clear division of tasks between networking and device configuration:
Network view – graphical connections between devices
Device view – parameterisation and configuration of the individual devices
Topology view – actual interconnection of PROFINET devices
The network view enables configuration of plant communication. The communication links between individual stations are displayed here graphically and very clearly.
- Combined view of all network resources and network components
- Fully graphical configuration of the individual stations
- Resources are networked by linking communication interfaces using drag&drop
- Multiple controllers, peripherals, HMI devices, SCADA stations, PC stations and drives possible in a single project
- Procedure for integrating AS-i devices identical to PROFIBUS/PROFINET
- Zoom and page navigation
- Copying/pasting entire stations, incl. configuration, or individual hardware modules
The configuration of racks and assigning of addresses etc is performed in device view. All devices are represented in a photo-realistic way.
- Buffering of configured hardware modules and reuse with module clipboard
- When zoomed to at least 200%, I/Os are displayed with the symbolic names / addresses..
- Automatic readout of available hardware with hardware detect
- Full text search in the hardware catalogue
- Option of filtering the hardware catalogue to show modules that can currently be used
- All parameters and configuration data are displayed on a hierarchical and context-sensitive basis
Decentralised peripherals on PROFINET are configured in network view. The controllers and the decentralised peripherals assigned to them can be shown graphically. During ongoing operation, however, it is not possible to see which ports are actually connected and communicating with each other.
Yet this is precisely what is often important for diagnostics. For PROFINET networks, the topology view enables this information to be displayed quickly and easily. An offline/online comparison identifies the communicating ports. By detecting, presenting and monitoring the physical connections between devices on PROFINET IO, the administrator can easily monitor and maintain even complex networks.
Powerful programming editors for efficient engineering
SIMATIC STEP 7 (TIA Portal) provides powerful programming editors for programming SIMATIC S7 controllers
Structured text (SCL), ladder logic (LAD) and function block diagram (FBD) languages are available for all controllers
Statement list (STL) and step sequence programming (GRAPH, SFC) are additionally available for the controller series S7-1500, S7-300, S7-400, WinAC and the S7-1500 Software Controller.
Functions such as drag & drop, project-wide cross-reference list and Autocomplete provide users with intuitive tools for all tasks. STEP 7 (TIA Portal) therefore enables efficient creation of user programs. It is also straightforward to have different programming languages in a single block.
Programming editors and the latest Windows technologies adapted to tasks and processing provide the basis for the intuitive STEP 7 (TIA Portal) operating concept. The embedding of the various editors in a common working environment ensures that all data is available to the user on a consistent basis and an overview of the project data is assured at all times.
Program blocks can be saved at any time. Troubleshooting is made easier and quicker thanks to several tools – a syntax window lists all errors in the current block. This permits simple navigation between the errors and has an indicator for faulty networks.
LAD and FBD – graphic programming languages
With STEP 7 (TIA Portal) , graphic programming languages are supported by new, high-performance compilers. Powerful tools and integrated functionality, such as indirect programming, boost engineering efficiency when creating programs.
The user-friendly, fully graphical LAD and FBD editors offer excellent clarity and fast navigation in the block editor thanks to
opening and closing entire networks
showing and hiding symbols and addresses
direct zooming and saving of layouts
a host of keyboard shortcuts
lasso function, copying and pasting for individual commands and command structures

SCL (Structured Control Language) – Programming of complex algorithms
The Structured Control Language (SCL) corresponds to the textual high-level language ST (Structured Text) defined in the standard IEC 61131-3 and fulfills base level and reusability level requirements according to PLC open. SCL is particularly suitable for the high-speed programming of complex algorithms and arithmetic functions and for tasks in data processing. The SCL code is simpler, shorter and clearer to produce and handle. Programming efficiency is enhanced using new, high-performance SCL compilers.
S7-SCL Editor offers the following functionalities
Complete areas of program code can be activated/deactivated with just one click
Loops and multi-line comments can be expanded and collapsed
Export of SCL code
Fast access to tag parts (bit, byte, word...) with "slicing"“
The values of all tags are displayed clearly online
SCL blocks can be used in other STEP 7 languages
Ideal for user-defined function blocks for libraries
SCL-blocks form the basis for sharing program code between S7-1200, S7-300, S7-400 and WinAC
Considerable time savings compared to programming in LAD/FBD/STL
STL – Statement list
The statement list (STL) textual programming language enables the creation of hardware-level runtime and memory-optimized user programs. .
It supports the user with a host of new user-friendly editing functions
Intelligent selection of symbols from PLC tags, DBs, local tags
Clear presentation even of complex program code
Code can be activated/deactivated with just one click
Option of adding display of absolute addresses

GRAPH (SFC) - Programming of sequencers
Sequential Function Chart (SFC) is used for describing procedures with alternative or parallel sequencers.
The sequencers are configured and programmed clearly and quickly in a standardized display mode (in line with IEC 61131-3, DIN EN 61131).
The process is described graphically and divided into individual steps with a manageable scope of functions.
Flexible sequencer structure:
Simultaneous and alternative branches, jumps within the sequencers, step activation and deactivation.
Selective processing of steps
The processing time of a sequencer is thus independent of the number of steps
Synchronisation of automatic and manual mode:
The process is no longer synchronous if it was put into a different state manually. GRAPH supports the locating of synchronization points for restarting automatic operation. The relevant steps are marked for this purpose. Transitions or interlocks can be defined as criteria
Single-step presentation shows all details of a step at a glance
Considerable time savings compared to programming in LAD/FBD/STL
Test- and diagnostics functions
Online functions: The online functions can result in considerable time savings, particularly during the commissioning phase. For example, active steps, the status of the interlocking, monitoring and step enabling conditions, and past actions can all be displayed online.
Efficient error analysis, fast commissioning and reduced downtimes
System diagnostics is an integral part of STEP 7 and does not require an additional licence.
No manual configuration of the system diagnostics is required in the engineering phase. Configuration of the diagnostics is integrated in the system in a user-friendly way and activated with just one click. When new hardware components are introduced, the diagnostic information is updated automatically via the engineering system (HWCN).
System diagnostics outputs all relevant information on existing errors in the system. This information is packaged automatically in messages containing the following elements:
Efficient error analysis and rapid error localisation with the new uniform display concept are available for S7-1500 controllers.
