Hello SIOS Forum Community, with every new construction and modernization of a machine, its safe operation must also be ensured after completion of the construction or modernization. With the help of the Machinery Directive, the plant builder or modernizer will find a legally prescribed set of rules that describes in detail the procedure from hazard analysis to risk reduction to validation of a safety application. Use of calculation tools for the creation of safety verifications As part of the validation of safety applications in accordance with the IEC 62061 and ISO 13849-1 standards, it is necessary, among other things, to calculate the safety level achieved using the safety-related characteristic values of the products used and to use this to demonstrate compliance with the normative specifications. Since the manual calculation procedures for creating safety verifications are very complex and also require a lot of experience from the user, calculation tools have been created that make the application significantly more convenient and safer. Provision of the Siemens VDMA 66413 characteristic value library for the SISTEMA calculation tool A calculation tool that is widely used on the market for creating safety verifications is the SISTEMA software wizard, which is offered by the German Social Accident Insurance (DGUV). (DGUV) is offered. With the neutral Siemens VDMA 66413 characteristic library as an XML file, Siemens provides all the characteristic data of fail-safe Siemens products which are suitable for import into SISTEMA. A detailed description of how to import the Siemens VDMA 66413 characteristics library into SISTEMA can be found on the DGUV website (SISTEMA Cookbook 5). Safety Evaluation in the TIA Selection Tool as a practical alternative to SISTEMA With Safety Evaluation with TIA Selection Tool, Siemens offers a free and convenient tool for creating safety certificates in accordance with the IEC 62061 and ISO 13849-1 standards. The advantage is that components for functional safety are specified in the TIA Selection Tool (TST) at an early planning and selection stage, and their safety characteristic values are stored there. This means that the components stored in the TIA Selection Tool project can be transferred directly to the Safety Evaluation Tool for testing.The Safety Evaluation in the TIA Selection Tool also offers the option of importing device characteristic values from other manufacturers and using them there for the calculation (assuming that the manufacturer provides the library).
