What is SISTEMA – and How is This Safety Software Used?

SISTEMA (Safety Integrity Software Tool for the Evaluation of Machine Applications) is a specialized software developed by the German Social Accident Insurance (DGUV) to help engineers and other safety professionals to evaluate the reliability and performance of machine safety functions. By automating complex calculations based on ISO 13849-1, SISTEMA helps ensure that safety-related control systems meet the necessary Performance Level (PL) requirements.

How SISTEMA Works

SISTEMA simplifies the analysis of functional safety by:

  • Modeling Control Systems – Users can create a digital model of their machine’s safety-related parts, including sensors, logic controllers, and actuators.
  • Calculating Performance Level (PL) – SISTEMA computes the achieved PL based on system architecture, component reliability, and diagnostic coverage.
  • Identifying Weak Points – The software highlights areas where safety improvements are needed to meet compliance standards.
  • Generating Compliance Reports – Detailed reports help document safety verification, aiding in regulatory compliance and audits.

Why SISTEMA Matters

Ensuring that industrial machinery meets safety requirements is critical for workplace safety, regulatory compliance, and operational efficiency. SISTEMA plays a key role in:

  • Compliance with ISO 13849-1 – Verifying that safety functions meet industry standards.
  • Reducing Human Error – Automating calculations minimizes the risk of manual miscalculations in safety assessments.
  • Cost-Effective Safety Planning – Early identification of deficiencies reduces costly redesigns and downtime.
  • Supporting Alternative Protective Measures (APMs) – Helps assess functional safety as a substitute for traditional Lockout/Tagout (LOTO) procedures.

Who Uses SISTEMA and SISTEMA Software?

SISTEMA is widely used by:

  • Machine Manufacturers – Ensuring their products meet global safety standards.
  • Safety Engineers & Consultants – Evaluating and certifying safety-related control systems.
  • Industrial Facilities – Assessing existing equipment for compliance and optimization.

If you’re a machinery manufacturer or system integrator, your customers may be asking you to provide a SISTEMA report or SISTEMA safety analysis on your fixed industrial machinery. If you’re struggling with where to begin with SISTEMA software, analysis, or reporting, a specialist trained in machine safety, risk assessment, and functional safety may be able to provide guidance.

How to Get Started with SISTEMA

Using SISTEMA requires an understanding of machine safety principles and functional safety engineering. At Machine Safety Specialists (MSS), our SISTEMA analysis services provide detailed evaluations of your functional safety system’s reliability, helping you to easily comply with modern safety standards.
