SIMATIC STEP 7 (TIA Portal)

SIMATIC STEP 7 in TIA Portal is the comprehensive engineering tool for configuring and programming SIMATIC controllers, whether PLC- or PC-based.

SIMATIC STEP 7 Professional (TIA Portal) can be used to configure, program, test, and diagnose all generations of SIMATIC controllers.

SIMATIC STEP 7 Basic (TIA Portal) is the price-optimized subset of STEP 7 Professional software that can be used both for engineering the SIMATIC S7-1200 Basic Controllers and for configuring the SIMATIC HMI Basic Panels, because WinCC Basic is part of the software package.

You can configure an entire plant using a single graphical editor. The editor offers three views to ensure clear division of tasks. The network view shows graphical connections between devices, the device view shows the parameterization and configuration of the individual devices, and the topology view shows the actual interconnection of PROFINET devices.

Network view

The network view enables the configuration of plant communication. The communication links between individual stations are displayed graphically and very clearly.

It’s possible to obtain a combined view of all network resources and components, link resources using drag & drop, and much more.

Device view

The configuration of racks and assigning of addresses etc. is performed in device view. All devices are represented in a photo-realistic way. When zoomed to at least 200%, IOs are displayed with the symbolic names or addresses.

Useful functions are buffering of configured hardware modules and reuse with module clipboard, automatic readout of available hardware, full text search in the hardware catalogue with optional filtering.

Topology view

For PROFINET networks, the topology view offers the option of showing which ports are interconnected and communicating with one another during ongoing operation.

By identifying, displaying, and monitoring the physical connections between devices on PROFINET IO, administrators can easily monitor and maintain even complex networks.

SIMATIC STEP 7 (TIA Portal) provides powerful programming editors for programming SIMATIC S7 controllers. These editors offer functions such as drag & drop, project-wide cross-reference lists, Auto Complete, etc., and enable the efficient creation of user programs.

Programming editors adapted to tasks and workflows provide the basis for the intuitive STEP 7 (TIA Portal) operating concept. Embedding the different editors in a common working environment ensures that all the data is available to users on a consistent basis and guarantees an overview of the project data at all times.

LAD and FBD

Graphical programming with Ladder and Function Block Diagram

STEP 7 (TIA Portal) supports graphical programming languages and, in this way, ensures a significant increase in engineering efficiency when programs are created.

The user-friendly, fully graphical LAD and FBD editors offer excellent clarity and fast navigation in the block editor, thanks to features such as opening and closing entire networks, showing and hiding symbols and addresses, convenience functions, and a calculate box that permits the direct entry of formulas with SIMATIC S7-1200 and S7-1500.

SCL

Programming of complex algorithms

The Structured Control Language (SCL) corresponds to the textual high-level language ST (Structured Text) defined in the IEC 61131-3 standard and fulfills base-level and reusability-level requirements according to PLCopen.

SCL is particularly suitable for the high-speed programming of complex algorithms and arithmetic functions as well as for data processing tasks. The S7-SCL Editor offers features such as aids for structuring code, slicing for fast access to tag parts, exchange options, and much more.

STL

Statement List as a textual programming language*

The Statement List (STL) textual programming language enables the creation of hardware-level runtime and memory-optimized user programs.

Users are supported by a host of new user-friendly editing functions, including intelligent selection of symbols from PLC tags, databases, and local tags, a clear presentation of even complex program code, and various other convenience functions.

*(No support for STEP 7 Basic)

Programming of sequencers*

Sequential Function Chart (SFC) is used for describing procedures with alternative or parallel sequencers. The sequencers are configured and programmed quickly and clearly in a standardized display mode (according to IEC 61131-3, DIN EN 61131). The process is described graphically and divided into individual steps with a manageable range of functions. Thanks to numerous convenience functions, sequencers can be easily and flexibly structured. In addition, online functions provide considerable time savings, particularly during the commissioning phase.

*(No support for STEP 7 Basic.)

Efficient error analysis, fast commissioning, and reduced downtimes

System diagnostics is an integral part of STEP 7 and does not require an additional license. In the engineering phase, diagnostics is conveniently activated with just one click. When new hardware components are introduced, the diagnostic information is updated automatically via the engineering system (HWCN).

Thanks to a real-time trace function, all user programs can be precisely diagnosed and optimized and, with the aid of online functions, a great deal of information can be retrieved and exchanged and projects updated.

Diagnostics

System diagnostics outputs all relevant information on existing errors in the system. This information is automatically packaged in messages containing the following elements:

Module
Message text
Message status

Efficient error analysis and rapid error localization using the new uniform display concept are available for the new controllers. The new uniform display concept enables identical visualization of error messages in TIA Portal, on HMI, on the web server, and on the display of the new CPU (S7-1500 only) as plain text information.

Benefits of integrated system diagnostics:

No programming of system diagnostics required
Rapid error localization
Automatic updating of system diagnostics if hardware configuration is changed
Transparent status messages for controllers, peripherals, and drives (motion control messages)
System diagnostics activated as standard for the new SIMATIC controllers
System diagnostics also available for S7-1500 controllers in the STOP operating mode

The real-time trace functions for SIMATIC controllers enable precise diagnosis and optimization for all user programs. You can easily identify sporadic events in the system during commissioning and maintenance by visualizing the entire process using a real-time trace.

The trace functionality offers:

Recording of up to 16 different signals
Up to 4 independent trace jobs simultaneously
Various trigger options
Two windows: analog and binary signals (logic analyzer)
Versatile zoom, cursor, and measuring functions
Export of measurements (e.g. for user-specific processing)

STEP 7 (TIA Portal) supports numerous online functions:

Online with just one click: display of operating status, diagnostic overview in the project tree, and online/offline comparison on the block level
Rapid transmission of all changes in the program with consistent download
Offline/offline project comparison
Download in RUN
Upload of hardware configuration from existing controllers with hardware detect
Complete software project upload to empty PG
Rapid service without an existing project (with hardware detect and software upload)

Together with TIA Portal, integrated and scalable SIMATIC Technology automation solutions save valuable engineering time and guarantee maximum efficiency and flexibility.
