Abstract

Systems, methods, and software for determining and visualizing reliability data for industrial automation equipment are provided herein. In one example, a non-transitory computer readable medium having stored thereon program instructions executable by a computing device is presented. When executed by the computing device, the program instructions direct the computing device to present a graphical user interface to receive a user selection for at least one operating parameter for the industrial automation device and identify a modified load profile based on at least a base load profile and the at least one operating parameter for the industrial automation device. The program instructions further direct the computing device to generate reliability information for the industrial automation device based on the modified load profile, and present an indication of the reliability information via the graphical user interface.
