1. A system, comprising:
a memory that stores executable components; and
a processor, operatively coupled to the memory, that executes the executable components, the executable components comprising:
a user interface component configured to
render a three-dimensional graphical representation of an industrial automation system based on a digital twin representing the industrial automation system, and
receive, via interaction with the graphical representation, input that adds one or more sensor objects to the graphical representation at specified locations and orientations within the graphical representation, wherein the one or more sensor objects represent respective one or more safety sensors;
a safety zone configuration component configured to record the specified locations and orientations in the digital twin based on the input; and
a safety zone simulation component configured to, for a sensor object of the one or more sensor objects, estimate a level of multipath interference experienced by a safety sensor represented by the sensor object based on analysis of the specified locations and orientations of the one or more sensor objects and physical obstructions defined by the digital twin, wherein
the safety zone configuration component is further configured to, in response to determining that the level of multipath interference exceeds a defined threshold, estimate a realignment of the sensor object that reduces the level of multipath interference and generate a recommendation to apply the realignment to the sensor object.
