SIMATIC Industrial Software Safety Engineering in SIMATIC S7 (see the following extract)
4.8 Safety requirements
Standardized Safety Requirements
The following safety requirements can be met with S7 Distributed Safety and S7 F/FH Systems F-Systems
· Safety class (Safety Integrity Level) SIL1 to SIL3 in accordance with IEC 61508
· Category 2 to Category 4 in accordance with EN 954-1

Determining the Safety Integrity Level in Accordance with IEC 61508-5
The qualitative methods of the risk graphs enable the safety integrity level for a safety related system to be determined based on knowledge of the risk factors involved:…


Notes:
1. the ISA (S5.x, S18.2) are not integrated in the automation equipment.
The ISA standards are for producing P&ID drawings and programmingblocks.
ISO9001 is a Quality Management(documentation compliance) standard.
Sinceapplication of these standards are in thedesign of the integrator, Siemens is not able to provide certification on them.

2. Since the design of the control panel is also done by the integration firm, do not take the NEMA 250 certification as part of Siemens' requirements.

3. The TÜV certificate above specifies that the F-DI modules of the ET 200ISP familydo not support NFPA 72, 79 and 85.

Hope this helps,
