A configuration system uses process plant items that may represent, or be capable of representing, entities in a process plant to assist in configuring, organizing, and changing the control and display activities within the process plant. Access to the items may be controlled by associating access control data with the items. The configuration system may also use objects that represent, or may be capable of representing, one or more steps to be performed by entities in the process plant. Access to these objects may be controlled by associating access control data with the objects. The access control data may indicate whether users or certain users may be able to, for example, view or modify all or some data associated with the process plant items or the objects. The process plant items may comprise, for example, module class objects which may be capable of generically representing process entities of the process plant, module objects which may be capable of specifically representing process entities of the process plant, composite templates, module templates, etc. The objects that represent, or may be capable of representing, one or more steps to be performed by entities in the process plant may comprise, for example, phase classes or unit phases.
