Safety Evaluation with the TIA Selection Tool according to  IEC 62061 and ISO 13849-1 standards lets you assess your machine’s safety functions quickly and easily. As a result, you are provided with a standard-compliant report, which can be integrated in your machine documentation as a proof of safety.

It goes without saying that system configuration can be performed in parallel for standard and failsafe devices. The Safety Evaluation, however, relates only to the safety-relevant part of the configuration.

Projects that have been created with the Safety Evaluation Tool cannot be transferred to the Safety Evaluation of the TIA Selection Tool.

You can perform a safety evaluation in accordance with both IEC 62061 and ISO 13849-1 using Safety Evaluation with TIA Selection Tool.

When you use Safety Evaluation with TIA Selection Tool, you can perform your safety evaluation right at the system configuration stage, so you can save valuable resources.

You can ensure the safety data from Siemens is up to date by running regular updates. You are responsible for third-party VDMA libraries and for integrating them.

Getting Started guides are available for all kinds of applications, and are available for downloading.

Safety-related modules that are not listed in the TIA Selection Tool because they are no longer current can be used for the Safety Evaluation from the Siemens VDMA library that has already been implemented.
(Example CPU 1516F-3PN/DP with article number: 6ES7516-3FN01-0AB0)

To create a 2-channel system with two devices (e.g. two contactors), the 2-channel subsystem element must always be used. For the parameter assignment of a 2-channel system within a device (e.g. EMERGENCY STOP), the desired architecture or category must be specified during the initial parameter assignment

All modules that do not have a predefined SIL/PL are suitable for the 2-channel subsystem element.

Modules from a wide range of VDMA libraries as well as user-defined modules can be used for the 2-channel subsystem element

The direct insertion of modules with predefined SIL/PL is currently not supported. To still be able to add them to the calculation, the failure rate λd of the module can be used with the help of a user-defined device.

During the initial parameter assignment, the architecture or category of the component must be chosen depending on the selected standard. To do this, a corresponding parameter must be selected based on the structure of the module used. For 1-channel modules, the architecture is 1-channel according to IEC 62061 or category B, 1 or 2 according to ISO 13849. For modules that have an internal 2-channel structure (e.g. EMERGENCY STOP operating devices), a 2-channel structure or categories 3 and 4 is required.

The safety guide for optimum machine safety

Machine safety is a complex issue. Technical measures for machine safety make a significant contribution. Standardization recommends implementing a structured process.
But what exactly might a well-structured process look like?
We will show you what aspects are important, what is entailed and how you can plan and implement such a process in an efficient manner. 


All benefits at a glance

The Safety Evaluation for the IEC 62061 and ISO 13849-1 standards lets you assess your machine’s safety functions quickly and easily, and you benefit from the flexibility and convenience of working with the TIA Selection Tool.

Proven benefits

Safety Evaluation with TIA Selection Tool continues the processes that are particularly important for Safety Evaluation: Automatically calculating and drawing up a report for machine safety in compliance with standards.

Additional benefits thanks to TIA Selection Tool

The convenient workflow offered by the TIA Selection Tool optimizes the job of assessing your machine’s safety functions and saves valuable time.

Data interface

Safety Evaluation in the TIA Selection Tool provides neutral VDMA 66413 data interface

Universal data base for safety-related characteristic values. The Safety Evaluation in the TIA Selection Tool makes it possible to import characteristic values from other manufacturers and use them for calculation (as long as the manufacturer provides them in the library).

Importing safety-related parameters

The Safety Evaluation in the TIA Selection Tool can be used to import characteristic values from third party products in VDMA 66413 XML format and use them for calculation. The safety parameters of Siemens products for import into other tools are available as an XML file via the link below.

Unified data interface

The standard sheet VDMA 66413 “Functional Safety – Universal data format for safety-related values of components or parts of control systems” describes a standardized electronic exchange format for safety-related parameters of automation components. The aim of the standard sheet is to provide the safety parameters in a consistent format for calculation tools in the interest of the users. 


Siemens collaborated extensively on defining the universal data format alongside other manufacturers and test agencies, such as IFA (Industrial Safety Institute of the DGUV), TÜV Rheinland, and TÜV SÜD.


Data import into the Safety Evaluation is performed using the menu item „Project“ -> „Import“ -> “VDMA library” which enables users to import third party VDMA 66413 XML files. Of course, it is also possible to enter safety-relevant product data manually.
