Safety Evaluation with TIA Selection Tool

To be able to comply with the mandatory documentation requirements for your existing projects, please create the necessary reports using the Report function before the changeover date. It will not be possible to migrate a Safety Evaluation Tool project into the new TIA Selection Tool environment.

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Safety-related modules that are not listed in the TIA Selection Tool because they are no longer current can be used for the Safety Evaluation from the Siemens VDMA library that has already been implemented.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.
