Project planning system, control program and method for checking consistent recording of pipelines in a project planning system

A method for checking the consistent recording of pipelines in a project planning system for recording and modeling components of an industrial process automation system, the method comprising:

• recording pipelines two-dimensionally in a first plan and three-dimensionally in a second plan into memory of the project planning system;
• determining, by a processor of the project planning system, at least one main path within each plan for each of the pipelines recorded in the first and second plans;
• determining, by the processor of the project planning system, sequences of objects comprising at least one of (i) line components, (ii) branches and (iii) connections for the main paths recorded within both plans which are each to be compared with one another;
• eliminating, by the processor of the project planning system, from sequences to be compared each object without a mutual correspondence which is at least one of (i) only recorded in one of the first and second plans and (ii) only recorded in one main path of one of the first and second plans;
• determining and classifying iteratively, by the processor of the project planning system, after elimination of the objects without mutual correspondence, objects with different ordering within the sequences to be compared which have a maximum order difference with respect to their ordering within the sequences to be compared;
• continuing, by the processor of the project planning system, determining the objects with different ordering until all objects remaining after classification have no order difference with respect to their ordering within the sequences to be compared;
• creating, by the processor of the project planning system, a correctly ordered assignment between corresponding objects recorded in the first plan and second plans;
• and
• displaying the correctly ordered assignment between corresponding objects recorded in the first plan and second plans on a graphical user interface;
• and
• operating the industrial process automation system based on the correctly ordered assignment between corresponding objects recorded in the first plan and second plans displayed on the graphical user interface.
