SISTEMA: Manufacturer-Independent, Simple and Reliable


Bosch Rexroth supports the manufacturer-independent software assistant SISTEMA

Software Assistant for Safety-Related Control Systems in Accordance with ISO 13849

Simplifying open standards and accelerating engineering processes are the stated aims of the SISTEMA software assistant, which has been developed by the Institute for Occupational Safety and Health of the German Social Accident Insurance (IFA). This free tool, recommended by the German Engineering Federation (VDMA) among other organizations, helps users to evaluate safety functions in accordance with the ISO 13849-1 standard. Designers use SISTEMA to recreate the structure of the safety-related parts of control systems based on the planned architectures, and then calculate reliability values including the performance level (PL) achieved. The tool is used by a host of manufacturers and provides a direct overview of the effect that every parameter modification has on the overall system.

Jochen Ost, Product Manager for Safety Technology at Bosch Rexroth, explains how and why Rexroth supports this software tool: "Lots of component libraries have been made available by various manufacturers for the manufacturer-independent software assistant SISTEMA. That is an advantage over manufacturer-specific tools that are normally limited to the manufacturer's products. As a provider of all types of drive technologies, Rexroth supports the IFA in its continuous and practice-oriented development of SISTEMA beyond the limits of technology. Our component libraries for selected technologies are constantly growing and play an important role in this regard. They enable easy access to typical safety-related parameters, such as MTTFd values used to calculate the probability of a hazardous breakdown. As these component libraries become more complete and comprehensive, engineering processes will become easier and safer for the designers."
