NOTICE!
Whenever DC = High is used in the circuit examples with safety analog inputs,
the following measure from ISO 13849-1
Cross monitoring of input signals and intermediate results within the logic (L),
and temporal and logical software monitor of the program flow and detection of
static faults and short circuits (for multiple I/O).
Whenever DC = Medium is used in the circuit examples with safety analog
inputs, any of the measures for input devices with DC ³ 90 % can be used from
ISO 13849-1 Ä [10].
