METHOD AND ARRANGEMENT FOR PLANNING AND/OR PROGRAMMING A PROJECT OF AN INDUSTRIAL AUTOMATION ARRANGEMENT

摘要

The invention relates to a method and arrangement for planning and/or programming a project of an industrial automation arrangement by a plurality of users, wherein a workstation (CL1, CL2, CL3) having at least one application for the planning and/or programming is associated with each of the users, wherein the project comprises a plurality of objects, and wherein at least one of the objects is accessed by a plurality of the workstations. At least a number of the objects is grouped into object groups (D1, D2, D3), wherein each of the objects groups (D1, D2, D3) is associated with a workstation, wherein the objects of an object group (D1, D2, D3) are stored in a respective physical memory of the workstation associated with said object group (D1, D2, D3), wherein a respective key is associated with each of the object groups (D1, D2, D3) and is stored in a data structure, wherein the data structure (DHT) for each of the keys specifies an identification for the workstation in the physical memory of which the object group (D1, D2, D3) associated with the key and the objects of said object group are stored, and the data structure (DHT) is accessed by a workstation in order to access an object, the storage location information associated with the key of the associated object group (D1, D2, D3) is determined by means of the access, and the object is accessed by means of the storage location. Such a method and such an arrangement guarantee a higher data throughput and also ensure that access to needed objects is guaranteed at any time.
