Functional Safety

Safety Lifecycle Services for the process industry according to IEC 61511

The topic of functional safety includes a lot more than the installation of SIL certified hardware and software components. Plant operators which use safety instrumented systems to reduce risks are obligated by IEC 61511 (and VDI/VDE 2180, respectively) to implement a holistic system for the management of the functional safety. This obligation applies to the operators of nearly all chemical plants and all refineries, distillation and combustion plants.

Siemens Functional Safety Services (FSS) therefore offers standardizes processes for fast und safe project implementations  and commissionings. Standardized engineering guide­lines and verification templates help to avoid mistakes right from the start.

  • Management and assessment of  functional safety and audits

  • Planning and implementation of the SLC (Safety Life Cycle)

  • Hazard and risk assessment

  • Allocation of the safety functions to the layers of protection

  • Specification of the safety requirements (SRS)

  • Verification and validation (e.g. SIL verifica­tion, hardware/software audit)

  • Test design

  • Training

Our services are ideally adjusted to the process control system PCS 7 with F-Systems and Safety Matrix but they are also designed to comply with a given safety integration level (SIL) as long as a project is in accordance with IEC 61511.
