1 Safety Integrity Software Tool for the Evaluation of Machines (SISTEMA)
Abstract
Safety related parts of machine controls were constructed an evaluated according to DIN 954-1. To take
more account of new technologies like electronic and software, this standard has been revised and is now
available in the revision DIN EN ISO 13849:1:2007. This standard combines established deterministic
features with the new requirements for the probability of default.
A BGIA (institute for occupational safety of the German statutory accident insurance) developed
technological aid is the software tool SISTEMA. This tool simplifies and speeds up the calculation of the
probability of failure, including the achieved performance level for planned or already implemented
controls. The different procedures of the standard are included in the software. The user needs only to
enter their data into the input masks. The result is calculated automatically and continuously. Comfort
features such as the results forecast, an excellent support, as well as the labor-saving way to create
libraries or to include them.
