Siemens SINAMICS S200 - Certification; PFH Values

The converter performs a self-test of the shutdown paths (Safe Torque O󹪜), functions as
well as interfaces (fail-safe digit
al inputs and outputs) cyclically and in compliance with the
standards. A test stop (forced checking procedure) by the operator is not required.
Note
Protection agains
t manipulation by unauthorized third parties
Safety Integrated Functions protect against hardware faults and software errors, but not against
manipulation by unauthorized third parties.
Protective measures against unauthorized manipulation are described in the Startdrive
Operating Instructions and online help. The measures address the following issues:
• Parameter con󹪝guration of the safety functions
• Connection
• Hardware components
9.8.2 Cer
ti󹪝cation
Descr
ip
tion
The Saf
e
ty Integrated Functions comply with:
• Safety Integrity Level (SIL) 3 according to IEC61800-5-2
• Performance Level (PL) e according to ISO13849-1
• Category 4 according to ISO13849‑1
The Safety Integrated Functions correspond to functions according to IEC61800-5-2.
9.8.3 PFH values
Description
The probability of failure for Safety Integrated Functions must be speci󹪝ed in the form of a PFH
value (Probability of Failure per Hour) according to IEC 61800-5-2, IEC 62061, and ISO 13849-1.
The PFH value of a Safety Integrated Function depends on the safety concept of the converter
and its hardware con󹪝guration, as well as on the PFH values of other components used for this
Safety Integrated Function.
