With the option package SIMATIC Step 7 Safety Advanced or SIMATIC Safety Basic , you can use all the benefits of the TIA Portal to create your safety functions too. Safety programs can be created in the programming languages LAD and FBD. PLCSIM also makes testing possible without anyhardware.


Use “ready-made” function blocks (e.g. emergency stop) out of the Step 7 Safety Library, or create and use your own in-house safety functions . This makes it possible to match the safety functions perfectly to the machines. 

Savings through standardization

Both programs/modules and hardware configurations can be saved in libraries and are secured using a unique CRC. This permits re-use and reduces the time and expense needed for testing. 

Testing without hardware

Programs can be tested in the TIA Portal, including the safety functions, using PLCSIM or PLCSIM Advanced with no need for hardware. This means the safety functions can be tested in advance to ensure correct implementation. 

Change management

Every module, and the entire program, is allocated a CRC that makes it possible to identify changes quickly. The overall signature can be easily displayed on the screen of the S7-1500 CPU, or via the web server, for example.

Fail-safe controllers for more flexibility

Complete scalability with integrated safety functions

The SIMATIC controller portfolio with integrated safety functions has the right controller for all your automation needs. The range of SIMATIC controllers includes Basic, Advanced, Distributed as well as Software Controllers, offering impressive scalability and functional integration. SIMATIC controllers can be flexibly expanded at any time with plug-in I/O modules, and function and communication modules. The fail-safe input and output signals can be recorded or controlled either via I/O modules or via PROFINET using PROFIsafe.

SIMATIC controllers are certified for applications in accordance with IEC 62061 to SIL 3 and EN ISO 13849-1 to PL e.

When high performance, a wide range of technological functions, flexibility and versatile communication features are required.

The CPUs are designed to allow the required safety functions to be perfectly integrated into the overall solution. The active safety program including its CRC, can be conveniently identified via the onboard screen, and diagnostic messages can be read in clear text.

The fail-safe Basic Controllers can also take charge of monitoring safety functions like a protective door with tumbler. The connection to the fail-safe sensor and actuator technology is either local via fail-safe signal modules, or remote via PROFIsafe.

Thanks to their compact design, Distributed Controllers are particularly suitable for series machine manufacturing. The integrated safety function makes the system particularly compact, since the absence of the safety controller that would otherwise be required saves space in the control cabinet. They can be accommodated in small control boxes directly on the machine.

In networked plants, connection to a production line’s central control cabinet is realized via PROFINET.

The CPU1507S F, a software controller with Safety Integrated, enables PC-based automation solutions to run on a SIMATIC IPC with a Windows operating system. The software controller shows its particular strengths when special automation functions have to be integrated using the programming languages C or C++ or when a close connection of Windows software to the software controller is required. Because the CPU1507S F can also perform safety-related tasks, there is no need for a second system to take care of these.

SIMATIC ET 200 – the ideal I/O, even for fail-safe tasks

With SIMATIC ET 200, a wide variety of I/O systems are available for standard and fail-safe automation – for solutions in the control cabinet or without a control cabinet directly at the machine. The modular design allows you to easily scale the ET 200 systems in small steps, for example, to expand with fail-safe I/O modules. The products can be consistently integrated into the automation system using PROFINET and/or PROFIBUS via PROFIsafe. All fail-safe I/O modules are certified for use in applications in accordance with IEC 62061 up to SIL 3 and EN ISO 13849-1 up to PL e.
