A version control system helps to keep track of versions of process plant items that may represent, or be capable of representing, entities in a process plant. The process plant items may comprise, for example, module objects which may be capable of specifically representing process entities of the process plant. These module objects may be created from module class objects which may be capable of generically representing process entities of the process plant. Version data is stored and associated with a module object. The version data may comprise data indicative of a version of a module class object that was used to create the module object. The version data may also comprise data indicative of a version of the module object. Configuration systems, version control systems, viewing systems, debugging systems, run-time monitoring systems, asset management systems, etc., may examine or permit viewing of the version control data associated with an item.
