Your step into the future - Migration made easy

Higher productivity, efficiency and availability through modernization

To stay competitive, machines and facilities have to be continually adapted to the latest requirements. If your automation system is no longer up to date, it is time for a modernization. In this process, each modernization has its own challenges. What is your individual goal: faster return on investment (ROI), lower total cost of ownership (TCO), higher availability, or shorter downtimes? No matter what your starting point is – an imminent generational change in the automation, a partial modernization, also from non-Siemens systems, or the modernization of a complete plant – Siemens offers you individual migration support to help you to reach your individual goals: from individual functions up to all-round service.

SIMATIC HMI - efficient to new level!

Performance benefits with the latest SIMATIC S7 generation 

The Basic Controller S7-1200 and the Advanced Controller S7-1500 are the new controller generation in the TIA Portal and a milestone in automation. They ensure maximum efficiency and, in combination with the TIA Portal, optimum usability for applications in machine and plant automation.

SIMATIC system migration to S7-1500

The SIMATIC S7-1500 is the latest generation Advanced Controller. This innovative, powerful automation system is used worldwide for factory automation.


There are good reasons to switch to our SIMATIC S7-1500 controller and start TIA Portal Engineering:

  • For a number of years, it has not been possible to use SIMATIC S5 and other controllers that have been in use for a long time for new applications and the end of the spare part supply is often imminent.

  • SIMATIC S7-300 and S7-400 are and remain fully developed, proven controllers. Many new requirements regarding handling and performance can no longer be fully met with the traditional architecture. This has led to the development of the next generation of S7-1500 controllers with improved system properties. The basic SIMATIC properties have been retained for compatibility.


With SIMATIC S7-1500, you are making a decision in favor of cutting-edge system architecture.  This architecture includes integrated technology functions and motion control, integrated trace possibilities, integrated safety, integrated security concept, and integrated system diagnostics. STEP 7 Professional in the TIA Portal is the common engineering platform for all SIMATIC S7-300, S7-400, S7-1200 and S7-1500 controllers. Together with the SIMATIC HMI Basic and Comfort Panels, the associated WinCC and the SINAMICS drives including Startdrive, you achieve an efficient, integrated solution.

Migration from SIMATIC WinAC to S7-1500 Software Controller

The S7-1500 Software Controller is revolutionizing PC-based automation by means of a complete decoupling of the PC-based controller from the Windows operating system. A basic new architecture exclusively assigns the existing PC resources such as processor cores, interfaces, as well as work memory and mass memory to the S7-1500 Software Controller. This enables Windows to be restarted even when the controller is running. In spite of this independence, communication with PC applications is supported. On the one hand, the open development kit ODK 1500S creates an interface to Windows applications and, on the other hand, high-level language applications can be directly integrated into the S7-1500 Software Controller even with real-time capability.

  • The S7-1500 Software Controller is available for the SIMATIC IPC 4x7D, 6x7D and 8x7D.

  • The uniform engineering in the TIA Portal means that no other Windows settings are required.

  • The functional scope of the S7-1500 Software Controller comprises all functions of the S7-1500 as well as integration of PC applications.These include know-how and copy protection, integrated trace, as well as standard motion functions.


The SIMATIC S7-1500 Software Controller offers significantly increased system availability. The innovative and unique architecture enables you to implement the control of your machine even for PC-based automation fully independently from Windows. Nevertheless, integrating PC applications into the controller is child’s play. Existing algorithms in high-level language can be easily incorporated by the ODK 1500S and an extensive range of ready-to-use applications is available for integration of PC applications.

SIMATIC system migration from S7-200 to S7-1200

The Basic Controller SIMATIC S7-1200 is the successor of S7-200, which has been declared a discontinued product. In addition to the engineering and system benefits, this argument speaks for a fast change:

  • Since the end of 2014, SIMATIC S7-200 is not available for new applications.

  • Decide in favor of modern system architecture: STEP 7 Basic in the TIA Portal is the common engineering platform which creates efficient, integrated solutions with the SIMATIC S7-1200 controller and the SIMATIC HMI Basic Panels.


SIMATIC system migration from ET 200S CPU to ET 200SP CPU

The Distributed Controller based on ET 200SP is the successor of ET 200S CPU (IM 151-8/IM 151-7). The functionality of the CPUs corresponds to that of the SIMATIC S7-1500.

With the ET 200SP Open Controller is at your disposal a PC based controller with visualization, Windows applications and central I/Os in a compact device.


The relocation of intelligence from the central control cabinet to Distributed Controllers on the individual stations entails positive effects on a plant's availability. Faults on one station can be rectified without leading to a standstill of the entire plant.

SIMATIC HMI - Efficient to a new level

Compared to older generations, new HMI devices always offer the latest display technology for improved display with more colors and higher resolution. Powerful processors and more RAM make for faster processing of larger amounts of data and let you implement applications with more functionality.

But SIMATIC HMI offers even more!


Efficient switch to new HMI generations with WinCC in the TIA Portal

The seamless integration of all SIMATIC hardware and software components lets you switch to a new, profitable HMI solution quickly and very efficiently.


Your benefits:

  • Efficient engineering means, for example, the avoidance of multiple entries and errors up front due to the availability of all data – anytime – in a common engineering platform, but also the reuse of proven elements thanks to the comprehensive library concept or the integrated conversion of devices.

  • With styles and designs of SIMATIC WinCC in the TIA Portal, you can give your machine a unique appearance and realize innovative operating concepts with unique user interfaces by means of integrated system functions – also with gestures and multitouch

  • Brilliant HMI devices – from standard to extreme, scalable for diverse requirements and reliable under any conditions with numerous certificates


    Our comprehensive offer in the Online Support Center provides answers to your questions regarding switching to the new SIMATIC HMI Panels.
