"X" indicates that the point is covered by this Typical.
Comment 1:
Designated architectures are described in Annex B of EN ISO 13849-1 and provide a simplified basis for the quantification.
Comment 2:
For complex electronics: Using designated architectures in compliance with EN ISO 13849-1 up to PL = d or every
architecture in compliance with EN 62061.
Comment 3:
For non-electrical systems: Use components that comply with EN ISO 13849-1 as sub-systems.
