Approvals

The classification of the functional safety always refers to the overall safety system. The
maximum safety requirements that can be achieved for an overall system are obtained from the
lowest achievable safety requirement of the individual safety-relevant components.
The Safety Integrated safety system with safety-relevant components of the F-PLC and
SINAMICS S drive system can be used up to the following safety requirements:
● SINAMICS Safety Integrated Functions:
– SIL2 - safety class (Safety Integrity Level) according to IEC 61508 and EN 61800-5-2
– Performance level (PL) d according to DIN EN ISO 13849-1
– Category 3 to DIN EN ISO 13849‑1
● F-PLC:
– SIL3 - safety class (Safety Integrity Level) according to IEC 61508
Note
F-system SIMATIC Safety/Safety Integrated is used to control processes, where a safe state
can be immediately achieved by shutting down.
It is only permissible to use SIMATIC Safety to control processes, where an immediate
shutdown does not represent any risk to persons and the environment.
Further information
Information about the maximum safety requirements that can be achieved for the individual
safety-relevant components is provided in the relevant documentation.
