Methods and module class objects to configure absent equipment in process plants

Methods and module class objects to configure equipment absences in process plants are disclosed. An example disclosed method of creating a configuration entity for use in configuring a process plant comprises creating a class object representative of a process entity within the process plant that includes a first data structure representative of one or more process elements that make up the process entity; and creating a module object based on the class object that includes a second data structure, the second data structure to include a configurable first indication to represent whether a specific process element that conforms to a first one of the one or more process elements that make up the process entity is absent
