Framework to efficiently configure, program, test and diagnose all modular and PC-based SIMATIC controllers


  • TIA Portal for engineering efficiency and reduced project costs
  • Short response times and high control quality
  • Integration of drives through motion control functionalities and PROFIdrive
  • Integrated system diagnostics for full transparency of the plant status, automatically generated and consistently displayed
  • Integration of Simulink models using the Simulink PLC Coder


The Totally Integrated Automation Portal (TIA Portal), provides an engineering framework for implementing automation solutions in all industries around the globe. From designing, commissioning, operating, and maintaining to upgrading automation systems, the TIA Portal saves engineers time, cost, and effort. SIMATIC STEP 7 in the TIA Portal is the software for the configuration, programming, testing, and diagnosis of all modular and PC-based SIMATIC controllers, and includes a variety of user-friendly functions.

Modular SIMATIC® controllers have been optimized for control tasks and specially designed for ruggedness and long-term availability. They can be expanded using plug-in I/O modules, function modules, and communication modules. Depending on the size of the application, you can select the right controller from a wide range according to performance, quantity frameworks, and communication interfaces. The modular controllers can also be used as fault-tolerant or fail-safe systems.

SIMATIC PC-based controllers use the real time-capable software controller WinAC RTX or its fail-safe variant WinAC RTX F on Windows® operating systems. Any PC applications, operator control and monitoring tasks, as well as technological functions can be combined to form an overall automation solution. The SIMATIC embedded bundles, with their highly rugged design and pre-installed, ready-to-use automation software, allow the advantages of PC-based automation to be implemented at the machine.

Simulink® models can be integrated into the PLC program using Simulink PLC Coder. To do this, Simulink PLC Coder generates SCL code (based on IEC 61131-3 structured text), that can be directly imported to a PLC program using SIMATIC STEP 7. Alternatively you can use the SIMATIC WinAC Target for a C/C++ based integration to the WinAC RTX PC-based controller.
