PFH values
Description
The probability of failure for Safety Integrated Functions must be specified in the form of a PFH
value (probability of failure per hour) according to IEC 61800-5-2, IEC 62061 and EN
ISO 13849-1. The PFH value of a Safety Integrated Function depends on the safety concept of the
converter and its hardware configuration, as well as on the PFH values of other components used
for this Safety Integrated Function.
More information
The PFH values can be found under: PFH values

You can map the PFH values of all Safety Integrated components
from Siemens using the "Safety evaluation" function in the TIA selection

EMERGENCY OFF and EMERGENCY STOP
Overview
In plants, systems and machines a distinction must be made between EMERGENCY OFF and
EMERGENCY STOP.
The Safe Torque Off (STO) and Safe Stop 1 (SS1) Safety Integrated Functions are suitable for
implementing an EMERGENCY STOP, but are not suitable for implementing an EMERGENCY
OFF.
