Safety Integrity Software Tool for the Evaluation of Machine Applications.  A Tool for the Easy Application of the Control Standard EN ISO 13849-1


Siemens has prepared a project  file for the SISTEMA Safety Tool, which is available from HMK Safety Engineering as a free download.  The project  file contains all the relevant safety data for the range of Siemens Safety products from PLC’s to Push Buttons.

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.

 

Relevant parameters such as the risk parameters for determining the required performance level (PLr), the category of the SRP/CS, measures against common-cause failures (CCF) on multi-channel systems, the average component quality (MTTFd) and the average test quality (DCavg) 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.

Rob Sharrock Business Unit Director of HMK Safety comments “Until now customers have had to enter data manually into the SISTEMA tool when using Siemens safety equipment.  The new project file makes the task much simpler and because Siemens has chosen to use a project file as opposed to a library file the data is secure and cannot be overwritten”
