SISTEMA and VDMA 66413 data and safety characteristics for Eaton products

Make safety of controls on machines easy

The manufacturer-independent calculation tool SISTEMA from the Institute for Occupational Safety and Health of the German Social Accident Insurances (IFA) provides assistance in the evaluation of safety-related control components in the context of EN ISO 13849-1 and simplifies risk assessment analysis.

Software SISTEMA

Selection of the design structure of the protective devices and the assignment to an architecture compliant to the EN ISO 13849-1 is implemented in a Windows user interface.

On this basis, the software calculates the reliability values as well as the attained Performance Level (PL).
A direct comparison with the required Performance Level (PLr) is thus possible.

The software records the relevant parameters for evaluation such as MTTFd, B10d, DCavg and CCF. It directly indicates the influence of variable parameters on the overall result.

Eaton provides the libraries for integration into the SISTEMA software at: Input, Logic or Output. Please note that the libraries are updated on an ongoing basis and new products are continuously added.

Further information and the SISTEMA software download can be found directly at the IFA.

Universal database for VDMA 66413 parameters

The EN ISO 13849-1, EN ISO 13849-2 and EN 62061 standards, which have been harmonised in accordance with the Machinery Directive 2006/42/EC, require assessments and calculations of the probability of a dangerous failure and of a machine’s systematic safety functions. We offer a database of Eaton logic modules for all manufacturer-specific calculation tools with a VDMA 66413-compliant import interface in both German and English (for the ESR5 and ES4P product ranges). In addition, the database also includes a description (IL) and a photo of each device. Project managers thus have direct access to the manufacturer's data via the software, meaning they do not have to be entered manually.

Safety-related characteristics

Functional safety includes calculation and documentation of the likelihood of failure for the individual safety functions. As a manufacturer of machines and equipment, additional characteristic values are required for safety-oriented products. The safety characteristic values are made available by the manufacturers of the products. These values are used together with statistical calculation tools to determine the attained safety level, known as a performance level in EN ISO 13849-1 or the Safety Integrity Level in IEC 62061 and IEC 61508.

Reliability values to EN ISO 13849-1:

B10d: Number of operations until 10% of the tested components fail dangerously
MTTFd: Mean Time To dangerous Failure. Average of the time expected up to a dangerous failure
PL: Performance Level

Reliability values to IEC 62061:

B10: Number of operations until 10% of the tested components fail
PFHd: Probability of dangerous Failure per Hour
SIL CL: Safety Integrity Level Claim Limit
