Standards For Implementing Safety-Related Controllers - Siemens SINAMICS S120 Function Manual

Standards for implementing safety-related controllers

If the functional safety of a machine depends on various control functions, the controller must
be implemented in such a way that the probability of the safety functions failing is sufficiently
minimized. The standards EN ISO 13849-1:2006 (previously EN 954-1) and EN 62061
define principles for implementing safety-related machine controllers which, when properly
applied, ensure that all the safety requirements of the EC Machinery Directive are fulfilled.
These standards ensure that the relevant safety requirements of the Machinery Directive are
fulfilled.
Figure 1-1
The application areas of EN ISO 13849-1:2006, EN 62061, and EN 61508 are very similar.
To help users make an appropriate decision, the IEC and ISO associations have specified
the application areas of both standards in a joint table in the introduction to the standards.
Either EN ISO 13849-1:2006 or EN 62061 is applied, depending on the technology
(mechanical, hydraulic, pneumatic, electrical, electronic, programmable electronic), risk
classification, and architecture.
