Standards For Implementing Safety-Related Controllers - Siemens Sinamics S110 Function Manual

8.1.2.3

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. EN ISO 13849-1 (formerly 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 8-1
The application areas of EN ISO 13849-1, 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.
EN ISO 13849-1 or EN 62061 should be applied depending on the technology (mechanics,
hydraulics, pneumatics, electrics, electronics, programmable electronics), risk classification
and architecture.
