| 1. An industrial automation system that visualizes availability and safety levels, comprising:
an optimization component that generates a voting configuration that provides an optimized combination of a safety level and
an availability level based upon available redundancy, the optimization component evaluates the safety level by summing probabilities
of failure associated with each device; and
a graphical user interface that presents a visualization of the safety level and the availability level, the graphical user
interface displays a graph that depicts the availability level of a safety function against the safety level by employing
a movable marker that indicates the availability level.
