The PFH
values for subsystems.
The user has the following options when setting up a safety-related controller:
● Use devices and sub-systems that already comply with EN 954-1 (or EN ISO13849-1),
● Develop own subsystems.
EN 62061 does not include information about non-electric systems. The standard provides
detailed information on implementing safety-related electrical, electronic, and programmable
electronic control systems. EN 954-1 / EN ISO 13849-1 must be applied for non-electrical
systems.
Note
Details of simple sub-systems that have been implemented and integrated are available as
functional examples.
Note
IEC 62061 has been ratified as EN 62061 in Europe and harmonized as part of the
Machinery Directive.

IEC/EN 61508, or IEC/EN 62061. The standard provides information specifying how
qualified devices can be integrated when safety functions are implemented.
– Programmable, electronic systems and complex systems: Application of EN 61508 or
EN 61800-5-2.
– Simple devices and subsystems: Application of EN 62061.
