Online tool for machine-safety calculation

The Safety Evaluation Tool automatically calculates the quality of safety functions in accordance with the standards EN 62061 (Safety of machinery – Functional safety of electrical, electronic and programmable electronic control systems) and EN ISO 13849-1 (Safety of machinery – Safety-related parts of control systems).

In the online tool, all the user has to do is to first specify the desired safety function, for example monitoring of a protective door. He can then use the examples provided or himself specify particular functions. After this, he enters the safety components that belong to his machine, namely sensors, evaluation unit and actuators.

He can select these components from a database of Siemens products that have already been certified according to the relevant safety standards. Products of other manufacturers can be entered manually. Finally, the tool calculates the Safety Integrity Level (SIL) or the Performance Level (PL). The result is a report that is in line with the standards. It is added to the machine documents and provides proof that the machine directive has been fully complied with.
