Safety Integrity Level (SIL) Concept
SIL Certification
This section provides the SIL certifications and Performance Level for the
controllers.
TÜV Rheinland has approved GuardLogix 5580 and Compact GuardLogix
5380 controller systems for use in safety-related applications where the de-
energized state is considered to be the safe state.
All I/O examples in this manual are based on achieving de-energization as the
safe state for typical machine safety and Emergency Shutdown (ESD) systems.
