SISTEMA (Safety Integrity Level Tool for Evaluation of Machinery Applications) is a free utility developed by the Institute for Occupational Safety and Health of the German Social Accident Insurance (IFA). It automates the calculation of the achieved Performance Level across a machine's entire safety chain—from sensors (inputs) to logic units (controllers) to actuators (outputs).

The result is modular, self-documenting code. If you need to insert a "Heat" step between Fill and Mix, you simply add a new step and adjust transitions. You don't risk breaking the CASE logic's index order.

Functional safety is a critical cornerstone of modern industrial automation. As manufacturing systems become more complex and autonomous, protecting human life and machinery requires rigorous compliance with international safety standards.

You can find the official SISTEMA data and related safety documentation through the following sources:

Before writing a single line of code, draw your machine states (using FB_StateMachine ) and your sequence steps (using FB_StepChain ). This forces rigorous thinking about transitions, especially error paths.

Provides audit-ready documentation required by CE, OSHA, and global safety auditors.
