Software-Assistent SISTEMA -
Safety Integrity Software Tool for the Evaluation of Machine Applications

A Tool for the Easy Application of the Control Standard EN ISO 13849-1

The SISTEMA software utility provides developers and testers of safety-related machine controls with comprehensive support in the evaluation of safety in the context of ISO 13849-1. The tool enables you to model the structure of the safety-related control components based upon the designated architectures, thereby permitting automated calculation of the reliability values with various levels of detail, including that of the attained Performance Level (PL). The SISTEMA program is now available with selection of English language. SISTEMA may be downloaded and distributed to third parties free of charge. Follow the Download button on the right-hand side.

Relevant parameters such as the risk parameters for determining the required performance level (PL_r), the category of the SRP/CS, measures against common-cause failures (CCF) on multi-channel systems, the average component quality (MTTF_d) and the average test quality (DC_avg) of components and blocks, are entered step by step in input dialogs. Each parameter change is reflected immediately on the user interface with its impact upon the entire system. Users are spared time-consuming consultation of tables and calculation of formulae, since these tasks are performed by the software. The final results can be printed out in a summary document.
